Introduction

This document provides a comprehensive defensive disclosure for US Patent 11825860, "Denatured milk proteins and methods of making them." The objective is to proactively publish technical variations and expanded applications of the core inventive concepts to preemptively render future incremental improvements or novel applications by competitors as obvious or non-novel. This disclosure explores material substitutions, operational parameter expansions, cross-domain applications, integration with emerging technologies, and inverse/failure modes for each independent claim.

Derived Variations for Independent Claims

Independent Claim 1: Denatured Whey Protein Composition (Low Fat)

• Claim 1: A denatured whey protein composition comprising: at least 60 wt. % protein on a dry weight basis; less than 8 wt. % native glycomacropeptide (GMP) relative to the total weight of the protein; greater than 2 wt. % enzymatically hydrolyzed GMP relative to the total weight of the protein; a proteolysis index of at least 8 wt. %; greater than 50 wt. % denatured whey proteins relative to the total weight of the protein; and at most 7.0 wt. % fat on a dry weight basis.

Derivative 1.1: Material & Component Substitution - Plant-Derived Protein Hydrolysates

• Enabling Description: A denatured protein composition is derived from a blend of pea protein isolate (PPI) and rice protein concentrate (RPC). The raw protein feedstock, comprising 80 wt.% PPI and 20 wt.% RPC on a dry weight basis, is subjected to a two-stage enzymatic hydrolysis. In the first stage, a bacterial endoprotease (e.g., Bacillus licheniformis protease, Alcalase®) is introduced at 0.05% (w/w protein) for 4 hours at 55°C and pH 8.0 to generate a spectrum of peptides, including those analogous in size and amino acid profile to GMP, followed by inactivation at 90°C for 5 minutes. The resulting hydrolysate is then passed through a selective ceramic microfiltration membrane (0.1 µm pore size, titania-zirconia composite) to retain higher molecular weight denatured protein fractions while allowing smaller peptides to permeate, achieving a "native GMP-like" peptide reduction of at least 70%. The retentate is then subjected to high-shear thermal denaturation at 180°C for 10 seconds under 20,000 s⁻¹ shear stress using a plate heat exchanger, resulting in a composition with >65 wt.% protein, <5 wt.% native GMP-like peptides, >5 wt.% hydrolyzed GMP-like peptides, a proteolysis index >10 wt.%, >70 wt.% denatured proteins, and <6 wt.% residual fat (from plant lipids) on a dry weight basis.

Derivative 1.2: Material & Component Substitution - Non-Caloric Fat Replacers

• Enabling Description: A denatured whey protein composition is prepared wherein the fat component (at most 7.0 wt.% on a dry basis) is entirely substituted with a non-caloric fat replacer based on a carbohydrate polymer, specifically microparticulated cellulose (e.g., Avicel® RC-591). The whey protein retentate (80% protein, <8% native GMP, >2% enzymatically hydrolyzed GMP, PI >8%, >50% denatured protein) is processed as per claim 1, and prior to final drying, a 3% (w/w) dispersion of microparticulated cellulose (particle size D50 < 5 µm) is intimately blended into the liquid concentrate. The blend is then subjected to flash pasteurization (72°C for 15 seconds) to ensure microbial stability without further protein denaturation, followed by spray drying. The resulting powdered composition maintains the specified protein, GMP, PI, and denatured protein levels, with the microparticulated cellulose providing rheological properties mimicking fat and contributing to a dry weight fat content of effectively 0% as per standard fat analysis methods.

Derivative 1.3: Operational Parameter Expansion - Microfluidic Reactor at Ultra-High Shear

• Enabling Description: A denatured whey protein composition is produced in a continuous-flow microfluidic reactor system. The reduced-GMP cheese whey retentate (diluted to 12% protein) is pumped through a serpentine microchannel array (channel dimensions 50 µm x 100 µm) while subjected to rapid ohmic heating. The temperature is rapidly increased from 50°C to 220°C within 50 milliseconds, sustained for 100 milliseconds, and then rapidly cooled to 30°C within 75 milliseconds. The microchannels are designed with chaotic advection mixers, generating localized shear rates exceeding 1,000,000 s⁻¹. This ultra-rapid, high-shear thermal treatment ensures complete enzyme inactivation and a high degree of protein denaturation (>85 wt.% denatured whey proteins). The resulting composition is then directly subjected to vacuum drying. This process yields a composition with at least 62 wt.% protein, less than 6 wt.% native GMP, greater than 4 wt.% enzymatically hydrolyzed GMP, a proteolysis index of at least 10 wt.%, greater than 85 wt.% denatured whey proteins, and at most 5.0 wt.% fat on a dry weight basis, characterized by a D50 particle size of less than 0.2 µm.

Derivative 1.4: Operational Parameter Expansion - Industrial Scale Production with Parallel Lines

• Enabling Description: A denatured whey protein composition is manufactured at an industrial scale utilizing a modular system comprising ten parallel processing lines. Each line processes 5,000 kg/hour of a reduced-GMP cheese whey retentate (14% protein solution). The retentate flows through a series of high-capacity tubular heat exchangers for enzymatic hydrolysis (5 hours at <45°F with inline static mixers to ensure homogeneity). Following hydrolysis, the stream enters a flash pasteurizer for enzyme inactivation and initial denaturation (190°F for 6 seconds), immediately followed by a high-capacity in-line colloid mill operating at 50,000 s⁻¹ shear for further denaturation and particle size reduction. The combined output from all ten lines is fed into a single, large-scale spray dryer operating with a residence time optimized for a target moisture content of <5%. This process ensures continuous production of denatured whey protein at a rate of 50,000 kg/hour, meeting the compositional specifications of at least 60 wt.% protein, less than 8 wt.% native GMP, greater than 2 wt.% enzymatically hydrolyzed GMP, a proteolysis index of at least 8 wt.%, greater than 50 wt.% denatured whey proteins, and at most 7.0 wt.% fat on a dry weight basis, with consistent particle size distribution across batches.

Derivative 1.5: Cross-Domain Application - Biopharmaceutical Excipients

• Enabling Description: A denatured whey protein composition, meeting the low-fat specifications, is formulated for use as a stabilizing excipient in biopharmaceutical products, specifically lyophilized vaccines. The protein composition, characterized by at least 60 wt.% protein, <8 wt.% native GMP, >2 wt.% enzymatically hydrolyzed GMP, PI >8 wt.%, >50 wt.% denatured whey proteins, and <7 wt.% fat, is further purified to remove endotoxins to <0.25 EU/mg and dialyzed to reduce mineral content to <0.1 wt.%. The resulting highly purified, denatured whey protein solution (10% w/v) is then combined with a model viral antigen at a 1:10 (antigen:protein) ratio. This blend is subjected to sterile filtration (0.22 µm) and subsequently lyophilized. The denatured protein matrix provides cryoprotection and thermoprotection for the antigen, ensuring long-term stability during storage and transport at varying temperatures, extending shelf life beyond formulations using traditional excipients like albumin or trehalose.

Derivative 1.6: Cross-Domain Application - Advanced Adhesives/Binders

• Enabling Description: A denatured whey protein composition, meeting the low-fat specifications, is utilized as a biocompatible adhesive and binder in tissue engineering scaffolds. The powdered protein composition (at least 60 wt.% protein, <8 wt.% native GMP, >2 wt.% enzymatically hydrolyzed GMP, PI >8 wt.%, >50 wt.% denatured whey proteins, <7 wt.% fat) is hydrated to a 25% (w/v) slurry using a phosphate-buffered saline (PBS) solution. This slurry is then applied as a binder for a polycaprolactone (PCL) fiber mesh, forming a composite scaffold. The denaturation of the whey protein enhances its binding capacity through increased exposed hydrophobic regions and reactive groups, forming strong interactions with the PCL. After solvent evaporation, the protein acts as a structural adhesive, providing mechanical integrity and cell adhesion sites for subsequent cell seeding, making the scaffold suitable for applications such as cartilage repair where biocompatibility and tunable degradation are crucial.

Derivative 1.7: Cross-Domain Application - Sustainable Packaging Coatings

• Enabling Description: A denatured whey protein composition, meeting the low-fat specifications, is employed as a biodegradable coating to enhance the oxygen barrier properties of polylactic acid (PLA) films for food packaging. The protein composition (at least 60 wt.% protein, <8 wt.% native GMP, >2 wt.% enzymatically hydrolyzed GMP, PI >8 wt.%, >50 wt.% denatured whey proteins, <7 wt.% fat) is dissolved in an aqueous ethanol solution (70% ethanol, 30% water) at a concentration of 5% (w/v). This solution is then applied to a pre-treated (e.g., corona discharge) PLA film via gravure coating. The denatured state of the protein facilitates denser packing and cross-linking upon drying, forming a continuous, low-permeability layer. After solvent evaporation and UV-curing (if cross-linkers are added), the coated PLA film exhibits a significant reduction in oxygen transmission rate (OTR) (e.g., from 150 to 5 cm³·m⁻²·day⁻¹), extending the shelf life of oxygen-sensitive packaged goods while maintaining biodegradability.

Derivative 1.8: Integration with Emerging Tech - AI-Driven Optimization

• Enabling Description: An AI-driven optimization system controls the enzymatic hydrolysis parameters and subsequent thermal denaturation for producing the low-fat denatured whey protein composition. Real-time data from an in-line near-infrared (NIR) spectrometer, capillary electrophoresis (CE) unit, and rheometer continuously monitors native GMP, enzymatically hydrolyzed GMP, total protein, and viscosity during processing. A deep learning model, trained on historical process data and product quality metrics (flavor, stability), dynamically adjusts enzyme concentration (e.g., alkaline serine protease and neutral protease), hydrolysis duration (5-72 hours), temperature (35-55°F), pH, and subsequent heating profiles (170-200°F, 5-90 seconds) and shear rates (10,000-100,000 s⁻¹) to maintain target specifications (e.g., native GMP <6 wt.%, proteolysis index >10 wt.%, DWP >70 wt.%) and optimize sensory attributes (e.g., minimize cardboard flavor). The AI predicts optimal parameters for incoming whey feedstocks with varying initial compositions, minimizing batch-to-batch variability and maximizing yield.

Derivative 1.9: Integration with Emerging Tech - IoT for Real-time Monitoring

• Enabling Description: Production of the low-fat denatured whey protein composition is monitored by an Internet of Things (IoT) sensor network. Each processing tank (for hydrolysis) and heat exchanger/shear mixer (for denaturation) is equipped with a suite of industrial IoT sensors: pH probes, thermocouples, pressure transducers, flow meters, and turbidity sensors. Vibration sensors are additionally installed on all rotating machinery (pumps, mixers, colloid mills) for predictive maintenance. All sensor data is streamed wirelessly via a LoRaWAN gateway to a cloud-based data platform in real-time. This allows for continuous visualization of processing conditions, anomaly detection, and alerts for deviations outside critical control points (e.g., unexpected temperature spikes during hydrolysis, abnormal viscosity changes during denaturation). Historical data is used for trend analysis and process optimization without direct human intervention in parameter adjustment (which would be handled by a separate AI system).

Derivative 1.10: Integration with Emerging Tech - Blockchain for Supply Chain Verification

• Enabling Description: The entire lifecycle of the low-fat denatured whey protein composition, from raw milk sourcing to final product packaging, is verified using a blockchain-based supply chain system. Each batch of raw milk from dairy farms is recorded on a private blockchain (e.g., using Hyperledger Fabric), including origin, fat/protein content, and microbial load. Upon arrival at the processing plant, all subsequent steps – ultrafiltration, enzymatic hydrolysis (enzyme lot numbers, supplier, activity certificate), thermal denaturation (temperature logs, shear rates, residence times), quality control results (native GMP, hydrolyzed GMP, proteolysis index, DWP, fat content), and packaging information – are immutably logged as transactions on the blockchain. Smart contracts automate quality checks and trigger alerts if parameters fall outside acceptable ranges. This provides end-to-end traceability and verifiable proof of quality for regulatory compliance, brand integrity, and consumer trust, accessible via a QR code on the final product packaging.

Derivative 1.11: The "Inverse" or Failure Mode - Controlled Renaturation Composition

• Enabling Description: A specialized denatured whey protein composition is engineered for controlled, gradual protein renaturation in response to specific environmental triggers, facilitating slow-release nutrient delivery in a liquid food matrix. The low-fat composition (at least 60 wt.% protein, <8 wt.% native GMP, >2 wt.% enzymatically hydrolyzed GMP, PI >8 wt.%, >50 wt.% denatured whey proteins, <7 wt.% fat) is further modified by partial chemical cross-linking of the denatured proteins (e.g., using transglutaminase) to create a stable, microparticulated aggregate (D50 < 1 µm). This aggregate is designed to contain latent refolding domains. When incorporated into a beverage with a precisely controlled pH range (e.g., pH 6.0-6.5) and ionic strength, and subjected to a mild, non-denaturing heating cycle (e.g., 40-50°C), a portion of the denatured proteins slowly refold over several hours. This controlled renaturation process alters the protein's hydration properties and digestibility kinetics, enabling a sustained release of amino acids or encapsulated micronutrients over time rather than an immediate protein spike.

Derivative 1.12: The "Inverse" or Failure Mode - Limited-Functionality for Enzymatic Substrate

• Enabling Description: A denatured whey protein composition is intentionally produced with high native GMP and minimal denaturation for use as an optimized enzymatic substrate for specific downstream applications, such as the production of therapeutic peptides. The whey protein feedstock is filtered (e.g., ultrafiltration to 80% protein) but without the selective enzymatic GMP hydrolysis step. Instead, it undergoes a minimal thermal treatment (e.g., 70°C for 5 seconds) primarily for pasteurization and to avoid significant denaturation. This process yields a composition with >75 wt.% total protein, high native GMP (>15 wt.%), low enzymatically hydrolyzed GMP (<1 wt.%), a low proteolysis index (<5 wt.%), and low denatured whey proteins (<20 wt.%). This "limited-functionality" composition (high native GMP, low denaturation) serves as a cost-effective, readily available substrate rich in native kappa-casein derived GMP for subsequent targeted enzymatic cleavage by specific proteases to produce defined bioactive glycopeptides or peptides, which would be hindered by extensive prior denaturation or GMP hydrolysis.

Independent Claim 15: Method of Making a Denatured Whey Protein Composition (Enzymatic Reduction)

• Claim 15: A method of making a denatured whey protein composition, the method comprising: filtering cheese whey from enzymatically coagulated milk, creating a retentate and a permeate; combining the cheese whey retentate with one or more enzymes that selectively hydrolyze GMP in the cheese whey retentate to form a reduced-GMP cheese whey retentate composition; and heating the reduced-GMP cheese whey retentate composition to form the denatured whey protein composition, wherein the denatured whey protein composition is characterized by containing at least 60 wt. % protein on a dry weight basis, less than 8 wt. % GMP and greater than 2 wt. % enzymatically hydrolyzed GMP relative to the total weight of the protein, a proteolysis index of at least 8.0 wt. %, and greater than 50 wt. % denatured whey proteins relative to the total weight of the protein.

Derivative 15.1: Material & Component Substitution - Hyper-Thermostable Microbial Proteases

• Enabling Description: The method for making a denatured whey protein composition utilizes hyper-thermostable microbial proteases for selective GMP hydrolysis. After filtering cheese whey from enzymatically coagulated milk to create a retentate (WPC80), this retentate is combined with a genetically engineered Pyrococcus furiosus protease (e.g., a modified Pfu protease exhibiting optimal activity at 90°C and pH 6.0-8.0) at a concentration of 0.005% (w/w protein). The hydrolysis step is performed at 85°C for 2 hours, which significantly accelerates GMP degradation while maintaining specificity due to the enzyme's designed resistance to thermal denaturation. This rapid, high-temperature hydrolysis negates the need for a separate enzyme inactivation step, as the subsequent heating for protein denaturation (e.g., 180°C for 15 seconds with 75,000 s⁻¹ shear) is above the enzyme's operational limit, ensuring complete deactivation. The resulting composition meets the specified protein, GMP, PI, and DWP criteria.

Derivative 15.2: Material & Component Substitution - Ceramic Microfiltration Membranes

• Enabling Description: The method for reducing native glycomacropeptides in cheese whey retentate employs advanced ceramic microfiltration membranes. Following the initial filtering of cheese whey, the retentate (e.g., 30% protein solution) is fed into a cross-flow microfiltration system equipped with silicon carbide (SiC) ceramic membranes. These membranes feature a highly uniform pore size distribution of 0.2 µm and a chemically inert, hydrophilic surface. The microfiltration process is precisely controlled to preferentially permeate native GMP and smaller peptides while retaining the larger beta-lactoglobulin and alpha-lactalbumin proteins, along with denatured whey proteins and fat. Operating at transmembrane pressures of 0.5-1.0 bar, this physical separation method effectively reduces native GMP to <10 wt.% without enzymatic hydrolysis. The reduced-GMP retentate is then heated to 195°F for 10 seconds under high shear conditions (30,000 s⁻¹) to achieve the final denatured whey protein composition.

Derivative 15.3: Operational Parameter Expansion - Supercritical CO2 Hydrolysis

• Enabling Description: The method incorporates enzymatic hydrolysis of GMP under supercritical CO2 (scCO2) conditions. The cheese whey retentate, concentrated to 20% protein, is injected into a high-pressure reactor along with a GMP-selective protease (e.g., alkaline serine protease) and liquefied CO2. The system is then pressurized to 8 MPa and heated to 40°C, establishing supercritical CO2 conditions. The scCO2 acts as a tunable solvent, enhancing enzyme kinetics by facilitating mass transfer of reactants and products, and enabling precise pH control through carbonic acid formation. This allows for reduced enzyme dosage (e.g., 0.001% w/w protein) and shorter hydrolysis times (e.g., 3 hours) to achieve the target GMP reduction. Following hydrolysis, the CO2 is depressurized and recovered, leaving a concentrated reduced-GMP retentate, which is then thermally denatured at 185°F for 8 seconds under mechanical shear (40,000 s⁻¹) to yield the final product.

Derivative 15.4: Operational Parameter Expansion - Ohmic Heating with Ultrasonic Cavitation

• Enabling Description: The heating and shearing steps for the reduced-GMP cheese whey retentate are achieved using a combined ohmic heating and ultrasonic cavitation system. The retentate, after enzymatic GMP hydrolysis, is passed through an ohmic heater unit where an alternating electric current directly heats the fluid rapidly and uniformly to 190°F in less than 2 seconds, ensuring instantaneous enzyme inactivation and protein denaturation. Immediately downstream, the heated fluid enters a custom-designed ultrasonic reactor, where high-frequency (20 kHz) ultrasonic waves generate cavitation bubbles. The collapse of these bubbles creates localized extreme shear forces (>150,000 s⁻¹) and microstreaming, effectively breaking up protein aggregates and reducing particle size, fulfilling the mechanical shear conditions. This integrated process provides superior control over denaturation kinetics and particle morphology, resulting in a highly stable, finely dispersed denatured whey protein composition.

Derivative 15.5: Cross-Domain Application - Wastewater Treatment (Protein Recovery)

• Enabling Description: The method is adapted for the recovery of valuable protein from industrial wastewater, specifically from a dairy effluent stream rich in milk solids. The wastewater is first pre-filtered to remove gross particulates. The protein-rich liquid, analogous to cheese whey, is then subjected to ultrafiltration to concentrate the protein, creating a "protein retentate" analogous to cheese whey retentate. This retentate is then combined with broad-spectrum proteases (e.g., a bacterial protease blend active across a wider pH range) to hydrolyze all undesirable proteins and peptides, including GMP-like structures, which are typically considered waste in this context, effectively reducing their "native GMP" equivalent. This hydrolysis step is performed at 45°C for 6 hours. Subsequently, the hydrolyzed mixture is heated to 180°F for 15 seconds and subjected to high shear (60,000 s⁻¹) to denature the remaining valuable proteins (e.g., albumins, globulins) for recovery via precipitation or centrifugation. The recovered denatured protein can be repurposed as a feed ingredient or industrial binder, demonstrating the utility of the method for sustainable protein valorization from waste streams.

Derivative 15.6: Cross-Domain Application - Biofuel Production (Enzyme Pretreatment)

• Enabling Description: The enzymatic hydrolysis and denaturation method is repurposed as a pretreatment step for lignocellulosic biomass in second-generation biofuel production. Lignocellulosic biomass (e.g., corn stover) is first pre-treated by mild acid hydrolysis to solubilize a portion of hemicellulose and create a "biomass hydrolysate" containing a mixture of sugars and protein-like compounds (e.g., from microbial contaminants or plant proteins). This hydrolysate is then treated with a targeted enzymatic blend, including specific proteases, to break down proteinaceous inhibitors of subsequent cellulase activity. This step is analogous to "selectively hydrolyzing GMP." The enzymatic treatment is conducted at 50°C for 8 hours. Following this, the biomass hydrolysate is rapidly heated to 170°F for 30 seconds to denature any remaining enzymes and protein inhibitors, and concurrently subjected to high-shear mixing (e.g., using a rotor-stator homogenizer at 40,000 s⁻¹) to reduce biomass particle size and expose cellulose fibers. This "denatured" biomass hydrolysate is then passed to a saccharification step with cellulases, improving glucose yield for fermentation into ethanol.

Derivative 15.7: Cross-Domain Application - Leather Tanning (Enzymatic Dehairing)

• Enabling Description: The selective enzymatic hydrolysis and denaturation principles are applied to the dehairing of animal hides in leather processing, replacing harsh chemical methods. Raw animal hides (e.g., bovine) are first subjected to a preliminary wash, similar to filtering cheese whey. The hides are then immersed in a solution containing a blend of non-specific alkaline proteases (e.g., derived from Bacillus subtilis, 0.5% w/v) at pH 9.0 and 30°C for 12 hours. These enzymes selectively hydrolyze the protein structures anchoring the hair follicles (analogous to GMP) without significantly degrading the collagen matrix of the dermis. This enzymatic step effectively removes hair while preserving the hide integrity. After dehairing, the hides are rapidly heated to 60°C for 30 minutes in a hot water bath (analogous to denaturation) to completely inactivate residual enzymes and to compact the collagen fibers slightly, improving their subsequent uptake of tanning agents. This process provides an environmentally friendlier alternative to traditional lime-sulfide dehairing.

Derivative 15.8: Integration with Emerging Tech - AI-Driven Dynamic Enzyme Dosing

• Enabling Description: The method for making denatured whey protein incorporates an AI-driven dynamic enzyme dosing system for GMP hydrolysis. An in-line spectrophotometer continuously measures the turbidity and specific peptide bonds indicative of GMP hydrolysis. This real-time data, combined with initial feedstock protein concentration and native GMP levels determined by predictive models, feeds into a recurrent neural network (RNN) controller. The RNN dynamically adjusts the dosage rate of the alkaline serine protease and neutral protease blend (0.001-0.05% w/w protein) into the cheese whey retentate, as well as fine-tuning the hydrolysis temperature (40-50°F) and residence time, to achieve a target native GMP reduction of >70% with minimal hydrolysis of other whey proteins. The system provides precise control, adapting to variations in raw material and environmental conditions, thereby optimizing enzyme usage and ensuring consistent product quality.

Derivative 15.9: Integration with Emerging Tech - IoT for Predictive Maintenance

• Enabling Description: The method's filtration and mechanical shear components are augmented with an IoT-enabled predictive maintenance system. Microfiltration membranes and high-shear mixers (colloid mills) are equipped with a network of high-frequency vibration sensors, differential pressure sensors, and acoustic emission sensors. Data from these sensors are wirelessly transmitted to an edge computing device for local pre-processing and anomaly detection using machine learning algorithms (e.g., support vector machines for pattern recognition). Critical events, such as unusual pressure drops across membranes (indicating fouling), increased vibration amplitude in mixers (indicating bearing wear or imbalance), or changes in acoustic signature (indicating cavitation or component degradation), trigger immediate alerts to maintenance personnel via a mobile application. This enables proactive scheduling of cleaning cycles, filter replacement, or equipment servicing, minimizing downtime and optimizing operational efficiency, thereby ensuring continuous production of the denatured whey protein composition.

Derivative 15.10: Integration with Emerging Tech - Blockchain for Process Auditability

• Enabling Description: An immutable blockchain ledger is integrated into the manufacturing method for end-to-end process auditability of the denatured whey protein composition. Every critical step and parameter – from the receipt of raw cheese whey (source, volume, initial composition) and enzyme batch IDs (supplier, activity, expiration) to precise hydrolysis parameters (start/end times, temperature profile, pH) and denaturation parameters (heating temperature, hold time, shear rate, equipment ID) – is recorded as a transaction on a permissioned blockchain (e.g., utilizing Ethereum's private network features). Each transaction is time-stamped, cryptographically secured, and linked to preceding and subsequent steps, forming an unalterable chain of custody and process history. This enables real-time auditing by regulatory bodies, transparent reporting for quality assurance, and automated verification against standard operating procedures, significantly enhancing traceability and compliance for food safety.

Derivative 15.11: The "Inverse" or Failure Mode - Maximized Bioactive Peptide Production

• Enabling Description: The method is inverted to specifically maximize the production of desired bioactive peptides from GMP hydrolysis, rather than minimizing native GMP for functional protein. The cheese whey retentate is combined with a highly specific exopeptidase blend (e.g., a combination of dipeptidyl peptidase IV and tripeptidyl peptidase I) chosen for its ability to cleave GMP into defined, smaller bioactive peptides (e.g., opioid peptides, immunomodulatory peptides). The hydrolysis conditions (e.g., 37°C for 24 hours at pH 7.0) are optimized for enzyme activity and desired peptide yield. The subsequent heating step is carefully controlled to only inactivate the proteases (e.g., 75°C for 1 minute) without further denaturing or degrading the newly formed bioactive peptides. This "fail-safe" inactivation ensures the preservation of the target peptides while halting further enzymatic activity, allowing for their efficient isolation and purification for nutraceutical or pharmaceutical applications. The resulting composition will have very low native GMP, but high levels of specific, non-GMP derived bioactive peptides, and lower overall DWP from major whey proteins due to the controlled inactivation.

Derivative 15.12: The "Inverse" or Failure Mode - Fail-Safe Enzyme Deactivation

• Enabling Description: A fail-safe mechanism for enzyme deactivation is integrated into the method. After selective GMP hydrolysis of the cheese whey retentate, the reduced-GMP composition typically proceeds to thermal denaturation for enzyme inactivation. In this derivative, a secondary chemical enzyme inhibitor (e.g., 0.1% w/v phenylmethylsulfonyl fluoride (PMSF) for serine proteases, or a metal chelator for metalloproteases) is introduced via an emergency dosing system in the event of a thermal inactivation system failure. An IoT sensor array monitoring steam flow, temperature probes, and a redundant pressure sensor in the heating unit triggers an alarm and automatically activates the inhibitor dosing pump if thermal deactivation parameters are not met within a predefined timeframe. The chemical inhibitor rapidly and irreversibly deactivates the enzymes, preventing further uncontrolled proteolysis and ensuring the stability and quality of the reduced-GMP composition before it can be diverted or safely processed via an alternative denaturation route.

Independent Claim 24: Denatured Whey Protein Composition (High Fat)

• Claim 24: A denatured whey protein composition comprising: at least 60 wt. % protein on a dry weight basis; less than 11 wt. % native GMP relative to the total weight of the protein; greater than 7 wt. % fat on a dry basis; a beta-lactoglobulin to alpha-lactalbumin ratio of greater than 5.00; and greater than 50 wt. % denatured whey proteins relative to the total weight of the protein.

Derivative 24.1: Material & Component Substitution - Plant-Based Structured Lipid Emulsions

• Enabling Description: A high-fat denatured protein composition is formulated using a plant-based structured lipid emulsion as the fat source. A whey protein concentrate (with inherent high beta-lactoglobulin to alpha-lactalbumin ratio from microfiltration) is denatured as per the patent (e.g., >60% protein, <11% native GMP, >50% denatured whey proteins). Separately, a palm oil-based structured lipid emulsion (70% fat content) is prepared using pea protein as a primary emulsifier, then further stabilized by high-pressure homogenization (200 MPa, 3 passes) to achieve a D3,2 mean droplet size of <0.2 µm. The denatured whey protein concentrate is then blended with this structured lipid emulsion in a ratio that yields a final composition with >60 wt.% protein, <10 wt.% native GMP, >12 wt.% fat (from palm oil), beta-lactoglobulin to alpha-lactalbumin ratio >5.50, and >55 wt.% denatured whey proteins on a dry weight basis. The structured lipid provides enhanced oxidative stability and controlled release characteristics, maintaining the creamy texture and fat-related functionalities.

Derivative 24.2: Material & Component Substitution - Modified Starch Hydrolysates as Emulsifier

• Enabling Description: A high-fat denatured whey protein composition incorporates a modified starch hydrolysate (e.g., octenyl succinic anhydride (OSA) modified waxy maize starch, Capsul®) as a secondary emulsifying agent and fat mimetic, partially substituting the inherent fat's emulsifying role. The denatured whey protein composition (at least 60 wt.% protein, <11 wt.% native GMP, beta-lactoglobulin to alpha-lactalbumin ratio >5.00, >50 wt.% denatured whey proteins, and >7 wt.% fat from milk) is processed as usual. During the concentration stage prior to drying, a 2% (w/w) solution of OSA-modified starch is incorporated. The OSA starch co-emulsifies with the denatured whey proteins, enhancing emulsion stability and contributing to desirable rheological properties in the final product. This allows for achieving the "greater than 7 wt.% fat" claim with potentially less actual milk fat, or improving the stability of higher fat levels, by leveraging the synergy between the denatured protein and the modified carbohydrate.

Derivative 24.3: Operational Parameter Expansion - Spray-Chilling with Encapsulation

• Enabling Description: A high-fat denatured whey protein composition is produced using a spray-chilling process coupled with microencapsulation for enhanced fat stability and controlled release. The denatured whey protein concentrate (meeting specifications for protein, GMP, beta-lactoglobulin/alpha-lactalbumin ratio, and DWP) is homogenized with a high fat content (e.g., 20 wt.% milk fat). This emulsion is then spray-chilled by atomizing it into a cooling chamber maintained at -10°C to -20°C, using liquid nitrogen or cold air. The rapid cooling solidifies the fat droplets, encapsulating them within a matrix of the denatured protein. This process leads to a powdered product where fat is highly stabilized against oxidation and phase separation, even at elevated fat levels (e.g., >15 wt.% fat). The resulting composition contains at least 60 wt.% protein, <11 wt.% native GMP, >15 wt.% fat, beta-lactoglobulin to alpha-lactalbumin ratio >5.00, and >50 wt.% denatured whey proteins, with improved flowability and shelf stability.

Derivative 24.4: Operational Parameter Expansion - High-Pressure Homogenization for Nanoemulsions

• Enabling Description: The high-fat denatured whey protein composition is produced using ultra-high-pressure homogenization (UHPH) to create a nanoemulsion, resulting in exceptionally fine fat droplet sizes and enhanced protein denaturation. The whey protein feedstock (with high beta-lactoglobulin content) and a high fat content (e.g., 18 wt.%) are combined and pre-heated to 60°C. This mixture is then subjected to UHPH at 200 MPa for 3-5 passes. The extreme shear forces during UHPH not only reduce the fat droplet size to a nano-scale (D50 < 100 nm) but also induce significant protein denaturation (>80 wt.% DWP) due to cavitation and shear stress, even at moderate temperatures, and further enhance the beta-lactoglobulin to alpha-lactalbumin ratio by preferential denaturation and aggregation of beta-lactoglobulin. The resulting composition, after subsequent spray drying, contains at least 60 wt.% protein, less than 11 wt.% native GMP, greater than 15 wt.% fat (as nanoemulsion), beta-lactoglobulin to alpha-lactalbumin ratio >7.00, and >80 wt.% denatured whey proteins, offering superior emulsion stability and functionality in food systems.

Derivative 24.5: Cross-Domain Application - Cosmetics/Personal Care Emulsifier

• Enabling Description: A high-fat denatured whey protein composition is utilized as a natural emulsifier and texturizer in cosmetic creams. The composition (at least 60 wt.% protein, <11 wt.% native GMP, >7 wt.% fat, beta-lactoglobulin to alpha-lactalbumin ratio >5.00, >50 wt.% denatured whey proteins) is micronized to a D50 particle size of less than 5 µm. This fine powder is then incorporated at 5% (w/w) into the oil phase (e.g., shea butter, jojoba oil) of an oil-in-water emulsion formulation for a moisturizing face cream. The denatured proteins, with their increased surface hydrophobicity and amphiphilic character, effectively stabilize the oil droplets in the aqueous continuous phase. The milk fat components within the denatured protein further contribute to the emollient properties and skin feel. The high beta-lactoglobulin content provides additional film-forming properties on the skin, enhancing moisture retention, making it a functional, bio-derived alternative to synthetic emulsifiers.

Derivative 24.6: Cross-Domain Application - Pet Food/Animal Nutrition

• Enabling Description: The high-fat denatured whey protein composition is formulated as a specialized ingredient for high-performance pet food, specifically for rapidly growing puppies or working dogs requiring high protein and energy density. The composition (at least 60 wt.% protein, <11 wt.% native GMP, >7 wt.% fat, beta-lactoglobulin to alpha-lactalbumin ratio >5.00, >50 wt.% denatured whey proteins) is optimized for digestibility. It is extruded with a blend of cereals and meats to form a dry kibble. The denatured protein and stabilized fat provide a highly bioavailable source of essential amino acids and fatty acids. The low native GMP content ensures palatability, while the high fat provides concentrated energy without increasing kibble volume. The specific beta-lactoglobulin to alpha-lactalbumin ratio is tailored to promote muscle development and immune function in target animal populations, enhancing the nutritional profile beyond standard protein meals.

Derivative 24.7: Cross-Domain Application - Advanced Drug Delivery Systems

• Enabling Description: A high-fat denatured whey protein composition is engineered for use in oral drug delivery systems, specifically for microencapsulating hydrophobic active pharmaceutical ingredients (APIs). The denatured whey protein (at least 60 wt.% protein, <11 wt.% native GMP, >7 wt.% fat, beta-lactoglobulin to alpha-lactalbumin ratio >5.00, >50 wt.% denatured whey proteins) is co-spray dried with a hydrophobic API (e.g., a poorly soluble anticancer drug) and an additional enteric polymer (e.g., Eudragit L100). The denatured protein matrix, particularly its exposed hydrophobic regions, serves as a carrier, encapsulating the API within the protein-fat microstructure. The fat component further aids in the solubility and bioavailability of the hydrophobic drug. The enteric polymer provides pH-sensitive release, ensuring the API is protected from gastric acid and released in the intestinal tract. This approach offers improved drug loading, stability, and bioavailability for challenging drug candidates.

Derivative 24.8: Integration with Emerging Tech - AI-Driven Formulation Optimization

• Enabling Description: An AI-driven formulation optimization platform is used to develop high-fat denatured whey protein compositions with tailored functional and sensory profiles. The AI model, trained on extensive data including rheological properties (viscosity, yield stress), sensory panel data (flavor, mouthfeel, creaminess), fat content, GMP levels, beta-lactoglobulin/alpha-lactalbumin ratio, and denaturation degree, predicts optimal processing parameters (e.g., heat treatment, shear, homogenization pressure) and ingredient ratios (e.g., initial fat content, protein concentration) for new product targets. For instance, a user might specify a target viscosity for a high-protein beverage and a specific creamy mouthfeel. The AI then suggests a high-fat denatured whey protein formulation and its manufacturing parameters to achieve these objectives, iterating through thousands of virtual experiments faster than physical prototyping.

Derivative 24.9: Integration with Emerging Tech - IoT for Real-time Emulsion Monitoring

• Enabling Description: Production of the high-fat denatured whey protein composition is equipped with an IoT sensor network for real-time monitoring of emulsion stability and rheology. In-line ultrasonic spectroscopy and dynamic light scattering (DLS) sensors are placed within homogenizers and mixing tanks to continuously measure fat droplet size distribution and zeta potential. Micro-rheometers monitor viscosity and viscoelastic properties during processing. Oxidative stability sensors (e.g., measuring oxygen radicals or volatile organic compounds) are integrated at various stages. All data is wirelessly transmitted to a cloud-based platform, enabling real-time visualization of emulsion quality. Alerts are triggered for any deviations, such as droplet coalescence, phase separation, or early signs of oxidative degradation, allowing for immediate corrective actions to maintain the desired high fat content and stability of the denatured whey protein.

Derivative 24.10: Integration with Emerging Tech - Blockchain for High-Value Ingredient Traceability

• Enabling Description: A blockchain-based system provides immutable traceability for the high-fat denatured whey protein composition, particularly relevant for its use in high-value nutritional or functional food products. Each batch of raw milk, cheese whey retentate (especially those with a high beta-lactoglobulin to alpha-lactalbumin ratio from specific microfiltration processes), and added fat ingredients (e.g., specialized dairy cream) is assigned a unique batch ID. All processing steps – microfiltration, denaturation temperatures, shear rates, homogenization pressures, and precise analytical results for native GMP, fat content, and protein ratios – are recorded as cryptographically secure transactions on a permissioned blockchain. This distributed ledger ensures tamper-proof verification of ingredient quality, processing integrity, and adherence to specific formulation standards. This is critical for premium products targeting specific health claims or dietary requirements, providing transparency to brand owners and consumers regarding the authenticity and provenance of the high-fat protein ingredient.

Derivative 24.11: The "Inverse" or Failure Mode - Controlled Phase Separation Composition

• Enabling Description: A high-fat denatured whey protein composition is designed for controlled phase separation, intended for applications where encapsulated active ingredients need to be released under specific environmental cues. The composition (at least 60 wt.% protein, <11 wt.% native GMP, >7 wt.% fat, beta-lactoglobulin to alpha-lactalbumin ratio >5.00, >50 wt.% denatured whey proteins) is engineered with specific, pH-sensitive protein-fat interactions. This is achieved by adjusting the iso-electric point of the denatured proteins through controlled enzymatic modification or pH adjustments during denaturation. The resulting microcapsules (API encapsulated within the fat-protein matrix) remain stable at neutral pH (e.g., pH 7.0). However, upon exposure to an acidic environment (e.g., pH < 4.0, simulating stomach conditions), the protein-fat matrix undergoes rapid and controlled destabilization and phase separation, leading to the rapid release of the encapsulated active ingredient. This "inverse" functionality targets drug delivery or flavor release applications.

Derivative 24.12: The "Inverse" or Failure Mode - Limited-Denaturation, High Native Fat Emulsifier

• Enabling Description: A high-fat whey protein composition is produced with minimal denaturation (e.g., <20 wt.% DWP) and high levels of native GMP (>12 wt.%), specifically for its natural emulsifying properties in applications where thermal processing of the final product is undesirable or where maintaining native protein structure is paramount (e.g., cold-processed dressings or specialized infant formulas). The high-fat whey protein feedstock (derived from microfiltration, already having high fat and a beta-lactoglobulin to alpha-lactalbumin ratio >5.00) undergoes only mild pasteurization (e.g., 65°C for 30 seconds) and mechanical homogenization without significant thermal or high-shear denaturation. This results in a composition with preserved native protein structures that act as superior natural emulsifiers for the high fat content, allowing for the creation of stable emulsions in cold applications. The resulting composition fulfills the high-fat and protein ratio criteria but deliberately falls below the "greater than 50 wt.% denatured whey proteins" requirement, demonstrating a functional inverse.

Combination Prior Art Scenarios with Open-Source Standards

This patent can be combined with existing open-source standards to demonstrate obviousness or lack of novelty for certain future improvements.

1. Enzymatic Hydrolysis + ISA-88 / BatchML (Bioreactor Control Standard)

   • Scenario: The method of selectively hydrolyzing GMP using enzymes (as described in Claim 15) is implemented and optimized using a control system compliant with the ISA-88 standard for batch process control and BatchML for data exchange. ISA-88 provides a standardized way to define recipes, phases, and operations in batch processes. A person of ordinary skill in the art, seeking to improve efficiency and reproducibility of the enzymatic GMP reduction, would find it obvious to apply well-established automation and control standards like ISA-88/BatchML to manage enzyme dosing, temperature profiles, and hold times in the hydrolysis reactors, especially given the patent's explicit mention of hydrolysis phases and temperature controls (e.g., "about 72 hours or less, such as about 5 hours or more" and "about 60° F. or less"). This combination would render any subsequent patenting of automated or flexible batch control for this specific enzymatic process obvious.
   • Open-Source Standard: ISA-88 (IEC 61512-1) / BatchML (Batch Markup Language, an XML schema for ISA-88).

2. Particle Size Control + GS1 EPCIS (Event-based Traceability Standard)

   • Scenario: The denatured whey protein compositions of Claims 1 and 24 emphasize specific particle size distributions (e.g., D50 < 4.5 µm, D90 < 8 µm, D50 < 0.3 µm for high-fat). A manufacturer looking to ensure consistent quality and traceability of these finely dispersed protein products would obviously integrate particle size data with an event-based traceability standard like GS1 EPCIS (Electronic Product Code Information Services). EPCIS provides a standard for sharing information about the movements and states of products as they travel through the supply chain. Capturing particle size distribution data (e.g., from a Malvern Mastersizer 3000, as mentioned in the patent) at the point of drying (operation 106 in FIG. 1) and linking it to the batch ID via an EPCIS event would be a straightforward application for quality assurance and recall management. Any patent attempting to claim "traceability of microparticulated denatured whey protein using particle size data" would be obvious in light of the patent's disclosure of particle size control and the widespread availability of EPCIS.
   • Open-Source Standard: GS1 EPCIS (ISO/IEC 19988).

3. Protein Fortification + Open-Source Recipe Management / ERP Systems

   • Scenario: The patent describes the use of denatured whey protein compositions (Claims 1 and 24) to fortify various food products (e.g., yogurts, protein bars, ready-to-drink beverages), achieving high protein levels with reduced viscosity and improved flavor. The development and scaling of such fortified food products routinely rely on open-source recipe management systems or enterprise resource planning (ERP) systems with open APIs (e.g., Odoo, ERPNext). These systems allow for the systematic creation, modification, and scaling of recipes, including precise ingredient dosing and process parameter management. A person of ordinary skill in the art, when developing new fortified food products using the disclosed denatured whey proteins, would find it obvious to integrate these ingredients into existing or open-source recipe management platforms to optimize formulations, manage ingredient inventories, and ensure consistent product manufacturing. Any claim attempting to patent "a method of formulating high-protein foods using denatured whey proteins via a digital recipe management system" would be obvious.
   • Open-Source Standard: Odoo (Community Edition), ERPNext, or other open-source ERP/recipe management systems.
