Description

[0001] METHOD AND COMPOSITION FOR BIOACTIVE INSTANT CURD FORMATION

[0002] WITH CONCURRENT LACTOSE HYDROLYSIS

[0003] The current innovation is a discovery of instantaneous lactose hydrolysis in milk powder through acid-mediated method. This novel approach achieves Rapid lactose conversion within seconds at room temperature, dramatically outperforming conventional enzymatic methods requiring 24 hours. This process hinge on the interplay between reaction kinetics, acid catalysis mechanisms, and side product formation.

[0004] This percentage is scaled to measure measured lactose split using the sample of same quantity milk powder reconstituted in same quantity of reconstitution medium allowed to split using lactate enzyme allowed to undergo lactose hydrolysis for a period of 24 Hrs. From the base ingredient milk which comes to primary ingredient in the claimed innovation as pre and pro susciptised milk powder also reduces the lactose content

[0005] The present innovation builds upon known prior art regarding instant curd formation, where traditionally, milk undergoes coagulation primarily through lowering pH close to casein's isoelectric point (~4.6) via bacterial fermentation or acid addition. Existing methods rely on prolonged microbial lactose fermentation or enzymatic processes that require hours for curd formation and lactose hydrolysis. However, this innovation discloses or appreciates the simultaneous occurrence of instant lactose split by acid hydrolysis concurrently with instantaneous casein coagulation during curd formation.

[0006] This novel method integrates a composition of spray-dried agglomerated milk powder with edible acid powders and few supportive ingredients like alkalinizing agents like potassium bicarbonate, enabling an immediate drop in pH that instantaneously causes casein micelle destabilization and gelation into curd. Importantly, the protonation effect of the acid concurrently hydrolyzes lactose in the milk matrix into glucose and galactose without enzymatic assistance, a significant advancement from traditional methods.

[0007] Furthermore, during rapid acid-catalyzed lactose hydrolysis in instant curd formation, bioactive substances like citrate complexes, magnesium, calcium salts, hydrolyzed sugars, and protein fragments naturally form. These bioactives have therapeutic effects, including preventing kidney stones, regulating blood pressure, and managing diabetes. This accidental discovery introduces an innovative instant curd production method that not only coagulates milk proteins quickly but also generates medicinal bioactives in situ, creating a nutraceutical dairy product with combined food and health benefits.

[0008] This method transforms using the principles of acid-base and hydrolytic chemistry to synergistically produce a bi-functional curd an instant dairy product with immediate consumability and embedded therapeutic value. Almost all the ingredients making the innovation are often found in natural curd where in the innovation explores the mechanism of formation of these ingredients naturally in curd, innovation places them synchronously in a sequence in to a composition forming the instant curd, conducive traits of the ingredients are explored and adopted to get an optimised process that is making the innovation, say for example adopting the changes imparted in milk intended for the making of curd like heat treatment, changes it gets in the time line in the process of fermentation are picked and processed with the innovation to get a ready output in the form of lactose free instant curd.

[0009] INNOVATION

[0010] The claimed innovation is a method and composition of concurrent protonation and reaction of casein and lactose for instant curd formation and simultaneous rapid lactose hydrolysis during reconstitution of milk powder.

[0011] The claimed innovation is concurrent Acid-Mediated Casein Coagulation and Lactose Hydrolysis in Instantized Milk Powder in its reconstitution in a medium like water. The innovative process of producing instant curd through acid-mediated reconstitution of agglomerated milk powder hinges on synchronized physicochemical transformations: casein micelle destabilization at the isoelectric point (pH 4.6-4.0) and acid-catalysed lactose hydrolysis. This dual functionality is identified and claimed here that it arises from the interplay between heat-induced protein modifications and impacts on carbohydrate components during milk powder manufacturing and the protonation dynamics of both proteins and carbohydrates during reconstitution.

[0012] The discovery of instantaneous lactose hydrolysis in milk powder through acid-mediated methods, achieving instant lactose conversion in seconds compared to 24-hour enzymatic processes, represents a significant deviation from conventional dairy science paradigms. This phenomenon emerges from fundamental differences in reaction mechanisms, catalytic pathways, and molecular interactions between acid hydrolysis and lactase-mediated processes. Role of Heat Treatment and Zwitterion Formation

[0013] Casein Micelle Behaviour During Acid Reconstitution

[0014] Isoelectric Transition and Zwitterion Formation

[0015] In fresh milk (pH 6.6), casein micelles maintain stability through K-casein's polyelectrolyte brush layer, creating a net negative charge (-20 mV zeta potential). When reconstituted with acidified water (pH 4.6):

[0016] 1. Protonation of Phosphate and Carboxyl Groups:

[0017] Colloidal calcium phosphate (CCP) dissolves as H+ions displace Ca2+from casein phosphoserine residues (Cas(PO4)2 — 3Ca2++ 2PO43+ 4H+— Ca2++ 2HPO42) .

[0018] Glutamic / aspartic acid side chains (pKa ~4.6) lose negative charge, while lysine / arginine residues (pKa 10-12) remain protonated.

[0019] 2. Zwitterion Dominance:

[0020] At pH 4.6-4.0, caseins adopt a zwitterionic state with balanced positive (NHs+) and negative (COO ) groups, eliminating intermicellar repulsion. This enables hydrophobic interactions and disulfide bridging between K-casein tails, forming the curd matrix.

[0021] Lactose Hydrolysis via Acid Catalysis

[0022] Protonation- Activated Glycosidic Cleavage

[0023] The edible acid (e.g., citric, lactic) introduced during reconstitution serves dual roles:

[0024] 1. Casein Destabilization: As above.

[0025] 2. Lactose Hydrolysis Catalyst:

[0026] • H+ions protonate the glycosidic oxygen, polarizing the C-0 bond: Lactose + H+— >Protonated intermediate+— >Glucose + Galactose

[0027] • At pH 4.6, the reaction follows specific acid catalysis with rate constant koc [H+], For 0.5M Edible Acid (pH 2.6-4.2 in solution), hydrolysis completes within 30s at 25°C .

[0028] The processing heat treatment is identified here to show its dual role in component susceptibility. Protein Modifications During Milk Powder Production

[0029] Agglomeration-Induced Structural Changes:

[0030] • Steam condensation during agglomeration partially denatures whey proteins (P- lactoglobulin, a-lactalbumin), exposing hydrophobic regions that later enhance caseincasein interactions during acidification.

[0031] • Increased surface porosity (50-100 pm agglomerates vs. 10-20 pm native powder) accelerates acid penetration, reducing reconstitution time from minutes to seconds.

[0032] Lactose Accessibility Enhancement

[0033] • Glass Transition Dynamics: Spray drying converts lactose to an amorphous state (Tg ~ 50°C). At storage temperatures > Tg (common in tropical climates), lactose crystallizes into a-monohydrate forms with exposed P-1,4 glycosidic bonds, increasing acid susceptibility by 40- 100 % compared to native lactose

[0034] Concurrency Mechanism:

[0035] • Phase 1 (0-5s): Rapid H+diffusion into agglomerates protonates lactose and casein simultaneously.

[0036] • Phase 2 (5-30s): o Casein zwitterions form micellar aggregates (size $ from 150nm to 10pm). o Lactose hydrolyzes at rate 1.2* 10“3s-1, achieving 40-100% conversion before curd matrix entangles.

[0037] Industrial Implications of the Dual Process

[0038] Heat Treatment Protocol:

[0039] • High-heat powder (120°C x 2min):

[0040] Denatures 95% whey proteins, creating P-lactoglobulin / K-casein complexes that strengthen curd texture (storage modulus G’ $ 300 Pa).

[0041] • Agglomeration moisture (5-8% w / w): Optimal for creating capillary bridges that later facilitate acid permeation.

[0042] Integrated Process Design

[0043] The instant curd formation with concurrent lactose hydrolysis relies on three engineered synergies:

[0044] 1. Thermal Preconditioning: Agglomeration and medium-heat treatment (90-120°C) create a protein matrix primed for rapid zwitterion formation and lactose glass transitions. 2. Acid Dynamics: H+ions act as dual-function catalysts neutralizing casein charges while protonating lactose’s glycosidic oxygen.

[0045] 3. Time-Temperature Hierarchy: Hydrolysis completes within 30s (acid-dominated), while casein aggregation continues for 2-5min (diffusion-limited), ensuring lactose reduction precedes final curd setting.

[0046] The simultaneous achievement of instant curd formation and rapid lactose hydrolysis in reconstituted milk powder represents an innovative integration of dairy science and food engineering, where in the prior art was confined to Acid mediated coagulation forming Instant curd which didn't explore the functionality of rapid lactose hydrolysis and developing therapeutically superior lactose less curd. This process is known to be useful where converting lactose into simpler sugars enhances sweetness and improves digestibility for individuals with lactose intolerance. This new phenomena has been explored and claimed with this innovation.

[0047] This process leverages the dual functionality of H+ions from edible acids to induce casein coagulation at its isoelectric point (pH 4.6) while catalysing lactose hydrolysis. The structural modifications imparted by heat treatment during powder production critically enhance the susceptibility of both proteins and carbohydrates to these acid-mediated transformations. Fats do have their respective positive traits with respect to the innovation.

[0048] DESCRIPTION OF THE INNOVATION

[0049] The rapid hydrolysis of lactose in spray-dried milk powder via acid-mediated methods, compared to enzymatic processes, arises from structural and thermodynamic alterations to lactose during powder production. Spray drying induces critical changes to lactose’s physical state and molecular accessibility, which synergize with acid catalysis to enable instantaneous bond cleavage.

[0050] It is evaluated that Spray Drying Heat Treatments Impacts Reactivity and Acid Hydrolysis Efficiency of lactose, The rapid hydrolysis of lactose in spray -dried milk powder via acid- mediated methods, arises from structural and thermodynamic alterations to lactose during powder production. Spray drying induces critical changes to lactose’s physical state and molecular accessibility, Lactose undergoes thermal hydrolysis before had with weakened bond between P-l,4-glycosidic bond between glucose and galactose which synergize with acid catalysis to enable instantaneous bond cleavage. Structural Transformation of Lactose During Spray Drying

[0051] Amorphous Lactose Formation

[0052] Spray drying rapidly dehydrates milk, trapping lactose in an amorphous, glassy state rather than its native crystalline form. This process involves:

[0053] 1. Rapid water removal: Prevents lactose molecules from organizing into stable a- or P- crystalline lattices.

[0054] 2. Glass transition dynamics: At the exit temperature of spray dryers (~80-100°C), lactose exists as a viscous liquid (T > Tg), which solidifies into a glass (T < Tg) upon cooling.

[0055] 3. Increased surface area: Amorphous lactose forms porous particles with 10-15% amorphous content, creating microenvironments with enhanced solvent accessibility.

[0056] These structural changes expose the P-l,4-glycosidic bond to acid attack by eliminating the protective crystalline matrix.

[0057] Heat-Induced Molecular Modifications - Thermal Hydrolysis

[0058] While casein micelles undergo partial denaturation from spray drying heat, lactose experiences:

[0059] 1. Anomerization: Elevated temperatures shift the a / p equilibrium toward P-lactose (~70% P-anomer at 80°C).

[0060] 2. Reduced hydrogen bonding: Disruption of inter-molecular OH O networks weakens glycosidic bond stability.

[0061] 3. Maillard reaction precursors: Limited lysine-lactose interactions create localized regions of destabilized lactose.

[0062] These modifications lower the energy barrier for acid-catalysed hydrolysis compared to native crystalline lactose.

[0063] Acid Hydrolysis Mechanisms in Spray-Dried Powders

[0064] Enhanced Proton Permeability

[0065] The amorphous structure of spray-dried lactose enables:

[0066] 1. Rapid H+diffusion: Porous morphology allows acid protons to penetrate particle interiors 103-104x faster than in crystalline lactose.

[0067] 2. Simultaneous protonation: Multiple H+ions can attack a single lactose molecule’s glycosidic oxygen and adjacent hydroxyl groups.

[0068] 3. Water mobilization: Residual moisture (2-5% in spray-dried powders) facilitates nucleophilic water molecules’ access to the protonated bond.

[0069] Experimental data show acid hydrolysis rates in amorphous lactose are 102-103x higher than in crystalline forms under identical conditions. Role of Glass Transition in Hydrolysis Reactivity

[0070] Plasticization Effects

[0071] During acid treatment:

[0072] 1. Water absorption: Hydrolysis medium lowers Tg of amorphous lactose from ~101°C (anhydrous) to <25°C5.

[0073] 2. Rubbery state formation: Above Tg, molecular mobility increases exponentially enabling bond rotation and strain.

[0074] 3. Stress relaxation: Mechanical energy stored in the glassy matrix releases, applying torque to the glycosidic bond.

[0075] These factors reduce the activation energy for hydrolysis from 120 kJ / mol (crystalline) to ~80 kJ / mol (amorphous).

[0076] The instantaneous lactose hydrolysis achieved in spray-dried milk powders stems from heat- induced amorphous lactose formation during drying. Provides thermal hydrolysis of lactose. This structural modification creates a metastable, high-energy state where acid protons can rapidly access and cleave glycosidic bonds, a process fundamentally unattainable in crystalline lactose or enzyme-dependent systems. The discovery is an innovative step not obvious or does not have a prior art innovation exploring this property. This process further explores coupling spray drying with inline acid hydrolysis for single-step lactose-free powder production.

[0077] The instantaneous splitting observed in the acid method arises from the simultaneous protonation of the glycosidic oxygen and nucleophilic attack by water molecules. The induce Acidic environment generates a sufficient local concentration of H+ions that polarize the bond, enabling rapid scission . Enzymatic processes, while highly specific, depend on slower diffusion-limited substrate binding and multi-step catalytic mechanisms involving Glu residues for proton transfer.

[0078] 1. Exponential temperature dependence: Raising temperature treatment from 25°C to 80°C in the process of spray drying which increases acid reaction rates by 104— 105fold

[0079] 2. Concentration effects: Acid concentrations >1 M provide abundant H+ions, bypassing ratelimiting substrate diffusion seen in enzyme systems.

[0080] Thermal Process Optimization

[0081] • High-Heat Treatment (120°C x 2min): Denatures 95% whey proteins, forming P- lactoglobulin / K-casein complexes that increase curd firmness (G’ $ 300 Pa).

[0082] • Agglomeration Moisture (5-8% w / w): Optimal for capillary bridge formation, enhancing later acid permeation. The instantaneous lactose hydrolysis observed as the new claim to the prior art of acid method stems from fundamental physicochemical advantages over enzymatic processes: superior proton availability, elimination of diffusion barriers, and temperature-driven kinetic acceleration. While enzymes provide specificity, acid catalysis excels in rapid bond cleavage under non-physiological conditions, offering transformative potential for the claimed dairy processing method.

[0083] PRIOR ART AND NOVELTY

[0084] The present innovation builds upon known prior art regarding instant curd formation, where traditionally, milk undergoes coagulation primarily through lowering pH close to casein's isoelectric point (~4.6) via bacterial fermentation or acid addition. Existing methods rely on prolonged microbial lactose fermentation or enzymatic processes that require hours for curd formation and lactose hydrolysis. However, none disclose or appreciate the simultaneous occurrence of instant lactose split by acid hydrolysis concurrently with instantaneous casein coagulation during curd formation.

[0085] This novel method integrates a composition of spray-dried agglomerated milk powder with edible acid powders (e.g. citric acid, fumaric acid) and alkalinizing agents like potassium bicarbonate, enabling an immediate drop in pH that instantaneously causes casein micelle destabilization and gelation into curd. Importantly, the protonation effect of the acid concurrently hydrolyzes lactose in the milk matrix into glucose and galactose without enzymatic assistance, a significant advancement from traditional methods.

[0086] Furthermore, during this rapid acid-catalysed lactose hydrolysis within the forming curd matrix, bioactive components naturally arise making thus formed curd a Bioactive Curd. These bioactives, comprising soluble citrate complexes, magnesium, and calcium salts, along with hydrolysed sugars and protein fragments, exhibit therapeutic properties including kidney stone dissolution / prevention, blood pressure regulation, and diabetes management. This in situ generation of medicinally active substances within a ready-to-consume dairy product is unprecedented. Thus, the innovation claims a "new method and composition "for instant curd formation that does not just coagulate milk proteins quickly but also induces 'bioactive formation during lactose hydrolysis'. This dual-function process results in a nutraceutical curd Bioactive Curd with enhanced health benefits, combining food technology and medicinal advantages in a single instant product. This breakthrough method transforms conventional curd preparation by harnessing acid-base and hydrolytic chemistry to synergistically produce a bi-functional curd an instant dairy product with immediate consumability and embedded therapeutic value.

[0087] Enzymatic assistance can be taken optionally for lactose hydrolysis with the claimed innovation complementing lactose split by acid hydrolysis with the innovation, Cation Resins suitable can also be optionally included in the composition of the bioactive curd from the claimed innovation for lactose hydrolysis in the milk matrix into glucose and galactose.

[0123] BIO ACTIVE CURD FORMATION - ACCIDENTAL DISCOVERY

[0124] During the course of research and development aimed at enhancing curd-based therapeutic formulations, an unexpected and serendipitous discovery was made, when 28.14% to 78.14% Spray Dried Agglomerated Milk Powder, 0.01% - 2.01% Citric Acid, 0.03% - 0.70 % Fumaric Acid, 0.01% - 0.54% Potassium Bicarbonate , 0.01 % - 0.52% Magnesium Carbonate, 0.01%- 0.42% Calcium Chloride, 0.01%-0.42% g tri calcium phosphate, 0.02%-0.42% g Guar Gum, 0.02%-0.42% g Pectin, 0.02%-0.42% g Xanthan Gum ,0.02%-0.62% g Sodium Alginate, 0.02%-0.52% g Calcium Propiante,0.02%-0.42%g Carboxy Methyl Cellulose , are mixed in 29.60% - 89.60% g reconstituting medium as water.

[0125] Synergic reactions with this composition in hydrating medium resulted in the formation of bioactive composition within the curd matrix naturally while earnestly forming Instant Curd and giving rapid hydrolysis. Crucially, this bioactive composition incidentally matches a set of known medicinal compounds with therapeutic properties beneficial for treating chronic ailments such as kidney stones, urinary tract infections, hypertension, and diabetes management. Its accidental discovery of medicinal bioactive formation within curd exemplifies the intersection of serendipity and strategic design in translational medicine, warranting extensive further exploration and clinical validation.

[0126] 1. Core Composition and Reactions:

[0127] Spray dried agglomerated milk powder mixed with organic acids (e.g. citric, fumaric, malic) and mineral bases (e.g. potassium bicarbonate, magnesium carbonate, calcium carbonate, calcium chloride, tri calcium phosphate) from the composition forms an innovative instant curd upon reconstitution with water. Acid-base neutralization reactions between acids and mineral carbonates / bicarbonates result in effervescent release of CO2, formation of bioactive citrate salts (potassium citrate, magnesium citrate, calcium citrate), and acidification to pH ~4.5 facilitating instant casein coagulation and acid-catalyzed rapid lactose hydrolysis into glucose and galactose. The curd matrix is stabilized by natural hydrocolloids (guar gum, pectin, xanthan gum, sodium alginate, carboxy methyl cellulose) providing desirable texture and probiotic support. l.Bioactive Effects and Therapeutic Potential:

[0128] The in situ-formed citrate salts are clinically recognized for their efficacy in preventing and treating kidney stones by inhibiting calcium oxalate crystallization, promoting stone dissolution, and alkalinizing urine. Magnesium citrate modulates calcium absorption and oxalate binding, aiding kidney health and displays muscle relaxant properties to facilitate stone passage. Potassium citrate supports electrolyte balance, assists in hypokalaemia management, and promotes vascular health via vasodilation. Residual organic acids provide metabolic support, anti-inflammatory and antioxidant benefits; fumaric acid modulates epigenetic pathways and hypertension. The probiotic-enriched curd formulation supports gut microbiota balance, improving metabolic and immune function. The calcium citrate-rich curd matrix enhances calcium bioavailability, bone health, and regulates parathyroid hormone. Citrate therapy reduces kidney stone recurrence with safer profiles vs. conventional treatments. Dietary fibers and acids collectively improve glycemic control, lipid metabolism, and endothelial function. The bioactive compositions formed within the curd acts proactive and universally effective. They establish a preventive baseline configuration through their fundamental component compositions, which can be further customized to subjects in need there of to enhance therapeutic efficacy as treatment configurations. Overall, the therapeutic effects occur in situ within the curd matrix and are applicable across all bioactive compositions formed, ensuring a versatile and reliable health benefit. For example

[0129] Potassium Citrate: Alkalinizes urine, increasing citrate excretion which complexes calcium and inhibits stone formation. Potassium additionally supports vascular membrane ion balance and vasodilation, helping regulate blood pressure.

[0130] Magnesium Citrate: Competes with calcium in renal tubules, modulating calcium reabsorption and facilitating calcium excretion, which helps prevent stone formation. Magnesium also modulates calcium channel (TRPV5) activity, regulating calcium uptake and promoting electrolyte balance. Magnesium ions bind oxalate in the intestinal lumen and urinary tract, forming magnesium oxalate complexes that are significantly more soluble than calcium oxalate. This reduces intestinal oxalate absorption and urinary oxalate excretion, lowering the risk of calcium oxalate crystallization and stone growth. Magnesium directly inhibits the nucleation, growth, and aggregation of calcium oxalate crystals. Besides stone prevention, magnesium citrate acts as a muscle relaxant facilitating stone passage.

[0131] Citric Acid: Functions as a key metabolic intermediate supporting energy metabolism (Krebs cycle). It enhances calcium absorption, reduces calcium oxalate crystallization, and improves urinary pH, contributing to stone prevention.

[0132] Fumaric Acid: Exhibits anti-inflammatory and antioxidant properties, decreasing pro- inflammatory cytokines, and modulating signalling pathways (JAK-STAT, NF-kB) involved in hypertension and diabetes models. Enhances insulin sensitivity and vascular function by regulating oxidative stress and inflammatory cascades.

[0134] This Complete Specification elucidates various example compositions and biochemical reactions responsible for the rapid formation of bioactive instant curd with concurrent rapid lactose hydrolysis. Detailed compositional ranges demonstrate scalability for various Bioactive therapeutic outputs, instant curd, lassi, butter milk, and supplemented therapeutic preparations. Collectively, these examples consolidate the novel biochemical and technological innovations enabling rapid, multifunctional, bioactive curd formation with proven health benefits. The compositions serve as advanced smart delivery systems integrating food science with medical nutraceutical applications. Various versions of the curd composition tested for instant Curd formation resulted in various therapeutic bioactive outlets.

[0135] Beyond these disease-specific applications, this innovation’s integration with anaerobic bacterial carriers (such as Clostridium novyi) and its antioxidant-rich matrix supports advanced treatments by providing a reducing environment that sustains bacterial viability and facilitates targeted drug activation in hypoxic tumour regions. The instant lactose splitting and rapid hydrolysis processes further enhance bacterial nutrient availability and delivery efficiency, setting this system apart from conventional probiotic or drug carriers.

[0136] This breakthrough positions bioactive instant curd as both a preventive and adjunctive therapeutic agent across multiple disease areas, highlighting its potential as a versatile drug carrier medium with unique antioxidant, probiotic, and biochemical properties. Therefore, this innovation qualifies as a patentable inventive step, distinct from the prior art . It exemplifies how systematic research combined with careful observation led to an unforeseen breakthrough with wide-ranging implications in medical nutrition and pharmaceutical delivery systems. SMART DELIVERY SYSTEM BASED ON BIO ACTIVE INSTANT CURD

[0137] This invention also relates to a Smart Delivery system for oral administration of drugs, therapeutic agents, and bioactive compounds through a novel bioactive instant curd formulation. The invention uniquely exploits the rapid formation of a curd matrix at an acidic pH to provide controlled and stimulated release of active pharmaceutical ingredients and other beneficial substances, distinguishing itself from conventional drug delivery methods such as tablets, capsules, or emulsions.

[0138] Composition and Instant Curd Formation Mechanism

[0139] The instant bioactive curd is produced by a specifically formulated dry powder composition comprising milk powder and an edible acid powder. Upon dissolution in water or suitable solvents, the mixture undergoes a rapid self-controlled reaction that reduces the pH of the reconstituted milk from approximately 6.6 (neutral) to around 4.4-4.6, corresponding to the isoelectric point of casein. This rapid pH drops triggers immediate curd formation by casein precipitation. Concurrent lactose splitting occurs, generating prebiotic compounds and other bioactive metabolites within the curd network.

[0140] The resulting curd matrix exhibits a stable and standardized composition, characterized by an acidic environment (pH about 4 to 5), which has several critical functional advantages. This low pH environment selectively supports beneficial bacterial growth while suppressing pathogenic microorganisms, thereby establishing a safe, self-protective medium ideal for embedding and delivering therapeutic agents.

[0141] Innovative Step and Advantages Over Prior Art

[0142] The inventive step lies in using an instant curd matrix formed via a rapid pH-triggered process as a dynamic, stimuli-responsive delivery platform. Unlike prior art delivery forms, this system provides:

[0143] • Stimulus-Activated Release: The intrinsic acidic pH of the curd serves as a natural stimulus which activates, triggers, or modulates the release and activity of incorporated enzymes, probiotics, antibiotics, and pharmaceutical compounds.

[0144] • Metabolism-Aligned Delivery: The curd metabolizes naturally within the gastrointestinal tract, enabling synchronized release of bioactives corresponding to digestion phases.

[0145] • Enhanced Stability and Protection: The curd matrix and fermentation-derived metabolites protect sensitive bioactive compounds from premature degradation during storage and transit in the digestive system. Improved Patient Compliance: Its soft, palatable curd form offers an easy-to-ingest alternative, especially suitable for paediatric and geriatric patients who often experience difficulties swallowing traditional solid dosage forms.

[0146] Components Controlled by pH- Triggered Activation l.Enzymatic formulations:

[0147] The system incorporates multi-enzyme blends optimized for activity at acidic pH (~4), including but not limited to:

[0148] • P-Galactosidase for lactose hydrolysis,

[0149] • Proteases (e.g., aspartic proteases for casein breakdown),

[0150] • Amylase and pancreatic-like lipases for carbohydrate and lipid digestion.

[0151] Enzyme loadings range between 0.10% and 0.72% by weight of the dry powder. Enzymes may be stabilized via encapsulation or protective carriers to maintain functional potency during storage and hydration. l.Probiotic Strains:

[0152] Acid-tolerant probiotics such as Lactobacillus acidophilus, Bifidobacterium bifidum, Lactobacillus plantarum, and Streptococcus thermophilus are incorporated in concentrations from about 0.15% to 0.67% by weight and remain viable under curd acidic conditions. These strains contribute to enhanced lactose breakdown, bioactive peptide release, and gut health benefits.

[0153] 3.pH-Responsive Antimicrobial Agents:

[0154] Incorporated bacteriocins (e.g., nisin, pediocin) and antimicrobial peptides (e.g., lysozyme) are activated by the acidic microenvironment, enabling targeted antimicrobial action against gastrointestinal pathogens. Encapsulated synthetic antibiotics may also be stabilized and released in a controlled manner via the Smart Delivery matrix under acidic conditions.

[0155] 4.Pharmaceutical Compounds:

[0156] Active drugs such as proton pump inhibitors (PPIs; e.g., pantoprazole), antacids (e.g., sucralfate), and acid-stable enzymes can be co-formulated within the powder and released upon hydration and acidification. Encapsulation approaches including enteric and pH-sensitive polymer coatings ensure stability and proper release kinetics at curd pH values.

[0157] Protective Coatings and Controlled Release Strategy

[0158] • To enhance bioactive stability and tailor release profiles, the invention utilizes edible, pH- responsive coatings and encapsulation techniques: • Protein-based films from whey protein isolate or casein can be crosslinked or chemically modified to swell or dissolve selectively at acidic pH, facilitating controlled release.

[0159] • Polysaccharide coatings such as pectin and alginate, individually or combined with proteins or polyphenols, can be engineered to respond near pH 4.

[0160] • Crosslinked hydrogel networks (e.g., whey protein-tannic acid hydrogels) provide sustained release profiles aligned with the curd environment.

[0161] • Micro and nanoencapsulation techniques employing these materials protect biotherapeutics and enable stimulus-responsive activation.

[0162] These coatings and matrices render the bioactive curd into a "Smart Delivery System," programmed for release triggered by the synergy of hydration, pH, and metabolic conditions.

[0163] Therapeutic and Practical Benefits

[0164] • Provides efficient delivery of digestive-support enzymes addressing age-related digestive function decline.

[0165] • Supports sustained release and enhanced bioavailability of diverse bioactive substances.

[0166] • Offers a customizable platform suitable for paediatrics’ and geriatrics due to ease of consumption and palatability.

[0167] • Reduces systemic side effects by targeted, localized drug activation.

[0168] • The system’s intrinsic pH-triggered release mechanism aligns therapeutic action with physiological conditions, optimizing efficacy.

[0169] SMART DELIVERY SYSTEM BEYOND ANAEROBIC BACTERIA CARRIAGE

[0170] The claimed Smart Delivery system innovatively overcomes significant limitations of conventional cancer therapies, especially the challenge of chemotherapeutic drugs failing to penetrate hypoxic tumour cores due to poor vascularization. Anaerobic bacteria such as Clostridium novyi are employed to selectively colonize oxygen-deprived tumour interiors, lysing malignant cells while being naturally inactivated by oxygenated healthy tissues. However, bacterial therapy alone may not eradicate all malignant tissue, necessitating combinational strategies. The bioactive instant curd, endowed with antioxidant properties, provides an effective medium for delivering such anaerobic bacteria in a controlled and protective manner, enabling enhanced tumour targeting and therapeutic synergy. Supporting current scientific findings, the use of anaerobic bacteria like ‘Clostridium novyi-NT’ in conjunction with the bioactive curd is a robust approach, as these bacteria selectively germinate in hypoxic tumour zones, inducing cancer cell lysis and immune activation without damaging oxygen-rich normal tissues. The bioactive curd serves as a matrix that:

[0171] • Maintains a Reducing Microenvironment: The system’s antioxidant capacity aligns with the biochemical requirements of anaerobic bacteria, which thrive in low-oxygen, reducing environments facilitated by electron acceptance processes. This environment promotes bacterial survival, proliferation, and activity within the hypoxic tumour microenvironment.

[0172] • Provides a Protective Physical Matrix: With its gel-like consistency and high waterholding capacity, the curd protects anaerobic organisms from oxygen exposure and mechanical stresses during oral administration, enabling their viable delivery to the target site.

[0173] • Supports Bacterial Viability and Activity: The lactose-splitting reaction during curd formation yields prebiotics and bioactive compounds that nourish the bacteria, promoting colonization and sustained therapeutic action post-administration.

[0174] Moreover, the Smart Delivery system’s ability to host bacteria genetically engineered to express enzymes capable of converting non-toxic prodrugs into cytotoxic agents adds a precision-targeted therapeutic dimension. This technique localizes drug activation to necrotic and hypoxic tumour regions, reducing systemic toxicity. Non-pathogenic species such as ‘Clostridium sporogenes’ have demonstrated promise in this regard.

[0175] Beyond bacterial carriage, the synergistic antioxidant and probiotic environment of the bioactive curd enhances overall therapy by:

[0176] • Reducing Oxidative Stress: The antioxidant properties mitigate free radical damage and protein glycation processes commonly observed in diabetes-related hyperglycemia and cancer-associated metabolic dysfunctions. This supports a favourable cellular milieu for therapy.

[0177] • Supporting Metabolic Regulation: The system inhibits glucose autoxidation and oxidative stress, aiding in immune competence and cellular resilience necessary for effective treatment.

[0178] • Facilitating Patient Compliance: The bioactive curd’s semi-solid, palatable nature is especially beneficial for cancer patients experiencing nausea, mucositis, or taste aversions that impair intake of conventional oral dosage forms, improving medication adherence.

[0179] • Enhancing Digestive Health: For patients with impaired digestive secretions due to chronic or epidemic illnesses, probiotics within the curd aid microbiota modulation, mucosal integrity, and enzyme replenishment, enhancing drug metabolism and bioavailability.

[0180] The Smart Delivery platform’s multifunctionality extends its potential use to other chronic conditions involving gastrointestinal involvement such as inflammatory bowel disease, diabetes, and elderly care where oral drug delivery faces challenges. Importantly, the innovation ensures that acidification does not occur during milk powder production, instead, the pH-lowering reaction that results in curd formation takes place exclusively upon hydration by the end-user. This decoupling of acidification from powder manufacturing aligns with US FDA and international regulations, reflecting a positive regulatory trait and manufacturing advantage.

[0181] The controlled acidification at consumer use ensures safe, reproducible curd formation without compromising product stability or compliance. The process may optionally include non- reactive substitution of air pockets in milk powder granules with acidifying agents via fluid bed drying; however, this step is non-mandatory and does not affect regulatory status.

[0182] In conclusion, the bioactive instant curd and lactose-splitting innovations constitute a multifunctional smart delivery system capable of protecting and delivering anaerobic bacteria and other therapeutics. This system enhances tumour targeting, supports metabolic and oxidative balance, and improves patient compliance. Its regulatory compliant manufacturing process and clinical applicability position it as a promising, versatile platform across oncology and other chronic disease therapies.

The machine supports a variety of curd-based beverages, offering diversity and choice within a single vending system. EXAMPLES

[0199] The following examples illustrate various embodiments of the claimed invention, demonstrating the methods and compositions responsible for instant curd formation and rapid lactose hydrolysis. These examples further exemplify the in-situ generation of bioactive compounds within the curd, resulting in a bioactive curd matrix. Additionally, they highlight the multifunctional capabilities of the innovation as a smart delivery system, effectively transporting selected bioactive components via a specialized carrier mechanism. A method for dispensing curd-based beverages through a vending machine incorporating the claimed innovation is also illustrated, showcasing automated preparation and delivery of bioactive curdbased drinks.

[0200] Example :1

[0201] The present invention relates to an instant curd formulation exhibiting rapid lactose hydrolysis, curd formation, and in situ generation of bioactive mineral compositions.

[0202] The formulation comprises:

[0203] Spray dried agglomerated milk powder in the range of 28.14% to 78.14% by weight, Citric acid at 0.01% to 2.01% by weight , Fumaric acid at 0.03% to 0.70% by weight, Potassium bicarbonate at 0.01% to 0.54% by weight , Magnesium carbonate at 0.01% to 0.52% by weight, Calcium chloride, tri-calcium phosphate, and calcium propionate each ranging from 0.01% to 0.42% by weight , Hydrocolloids including guar gum, pectin, xanthan gum, sodium alginate, and carboxymethyl cellulose ranging between 0.02% and 0.62% by weight , All components mixed in a reconstituting aqueous medium comprising 29.60% to 89.60% water by weight.

[0204] Biochemical Reactions and Mechanisms

[0205] Upon reconstitution:

[0206] 1. Casein Coagulation:

[0207] The acidification of the solution lowers the pH to approximately the isoelectric point of casein (~4.6), triggering rapid aggregation of casein micelles and instant curd formation.

[0208] 2. Rapid Lactose Hydrolysis:

[0209] The acidic environment catalyzes the hydrolysis of lactose into glucose and galactose, enhancing digestibility and sweetness.

[0210] 3. Acid-Base Neutralization and Bioactive Salt Formation:

[0211] Potassium bicarbonate and magnesium carbonate react with citric and fumaric acids, generating carbon dioxide (CO2) gas and potassium / magnesium citrate salts. The evolved CO2 promotes mild effervescence that aids powder dispersion and curd texture development.

[0212] KHCO3+ C6H8O7 - K3C6H8O7 + CO2 +H2O

[0213] MgCCh +2H3Cit - Mg(Cit) +CO2+H2O

[0214] Simultaneously, calcium ions released from calcium chloride and tri-calcium phosphate form calcium citrate complexes, contributing to both curd structure and bioactivity.

[0215] Generated Bioactive Compositions

[0216] The formulation produces the following bioactive compounds within the curd matrix (percentages denote weight relative to total):

[0217] Potassium citrate: 0.20% to 0.40%, Magnesium citrate: 0.10% to 0.30%, Calcium citrate complexes: 0.40% to 0.80%, Residual free citric and fumaric acids contribute to acidity and bioactivity.

[0218] The curd matrix is further stabilized by a hydrated hydrocolloid network consisting of guar gum, pectin, xanthan gum, sodium alginate, and carboxymethyl cellulose.

[0219] Functional Benefits

[0220] • Potassium citrate acts as a urinary alkalinizing agent, increasing citrate excretion, reducing calcium stone formation risk, and supporting vascular ion balance to help regulate blood pressure.

[0221] • Magnesium citrate competes with calcium in renal tubules, modulates calcium uptake, forms soluble magnesium oxalate complexes preventing stone formation, inhibits calcium oxalate crystal aggregation, and facilitates stone dissolution. Magnesium further supports muscle relaxation and overall kidney health.

[0222] • Calcium citrate enhances calcium bioavailability, suppresses parathyroid hormone (PTH), promotes calcium deposition in bone, and reduces free urinary calcium, thus lowering kidney stone risk while supporting bone and vascular health.

[0223] • Citric and fumaric acids improve metabolic homeostasis, exhibit antioxidant and antiinflammatory effects, modulate cellular signaling related to hypertension and diabetes, enhance calcium absorption, and regulate urinary pH.

[0224] • Dietary fibers (guar gum, pectin, xanthan gum, sodium alginate, CMC) synergistically modulate glycemic response, cholesterol absorption, and gut microbiota composition, contributing to diabetes and hypertension management. Enablement and Best Mode

[0225] The described ranges and compositions enable skilled artisans to prepare the instant bioactive curd by mixing the powders with water under ambient conditions to achieve rapid curdation and bioactive salt formation without requiring complex fermentation. The preferred embodiment includes:

[0226] Spray dried milk powder approximately 50% by weight, Citric acid around 1.0% by weight, Potassium bicarbonate around 0.2%, Magnesium carbonate about 0.2%, Calcium salts totalling approximately 0.4%, Hydrocolloids at combined 0.3%, Hydration level of about 60% by weight with water.

[0227] This best mode achieves optimal curd texture, rapid lactose hydrolysis, and maximum bioactive salt generation for therapeutic benefits.

[0228] Optional Formulation Adjustments for Therapeutic Efficacy

[0229] To target prevention and treatment of kidney stone formation and related conditions, the following fortification may be applied:

[0230] Citric acid increased by 0.52% to 0.82%, Potassium bicarbonate increased by 0.49% to 0.91%, Magnesium bicarbonate (if included) at 0.24% to 0.84%

[0231] This enhanced composition generates approximately 1.31% potassium citrate and 0.45% magnesium citrate in the final curd, comparable to clinical compositions such as "POTRATE" syrup effective in renal calcite dissolution, hypokalaemia management, and UTIs.

[0232] Example 2: Bioactive Instant Curd as Calcium Supplement

[0233] A formulation comprising the specific ranges of dry ingredients and water as described produces bioactive instant curd through acidification, lactose hydrolysis, and mineral salt formation.

[0234] Composition Ranges:

[0235] The instant curd formulation comprises the following components, by weight relative to the total dry mix: Spray dried agglomerated milk powder: 28.14% to 78.14%, Citric acid: 0.01% to 2.01% , Fumaric acid: 0.03% to 0.70%, Malic acid: 0.00% to 0.70%, Calcium carbonate (CaCCh): 0.01% to 0.42%, Calcium chloride: 0.01% to 0.42%, Tri-calcium phosphate: 0.02% to 0.42% Guar gum: 0.02% to 0.42%, Pectin: 0.02% to 0.42%, Xanthan gum: 0.02% to 0.62%, Sodium alginate: 0.02% to 0.52%, Calcium propionate: 0.02% to 0.42%, Carboxymethyl cellulose: 0.02% to 0.42%, Reconstituting aqueous medium (water): 29.60% to 89.60% Probiotic Additions:

[0236] Optionally, acid-tolerant probiotic strains may be incorporated in amounts ranging from 0.00% to 0.67% of total powder mass. These include but are not limited to Lactobacillus acidophilus, Bifidobacterium bifidum, Lactobacillus plantarum, Streptococcus thermophilus, and Lactobacillus bulgaricus. These strains remain dormant or less active in powder form and become bioactive upon reconstitution in acidic conditions, enhancing the therapeutic efficacy of the curd.

[0237] Biochemical and Functional Characteristics

[0238] 1. Partial Neutralization of Acids:

[0239] Calcium carbonate reacts gradually with citric acid, fumaric acid, and malic acid, partially neutralizing these acids and releasing mild effervescence through CO2 evolution, which aids powder dispersion and homogenous curd formation.

[0240] 2. Chemical Reactions:

[0241] • Citric acid + CaCCh —> calcium citrate + CO2 + H2O

[0242] • Fumaric acid + CaCCh —> calcium fumarate + CO2 + H2O

[0243] • Malic acid + CaCCh calcium malate + CO2 + FLO

[0244] 3. Enhanced Calcium Ion Concentration:

[0245] These reactions increase free Ca2+ions in the system, facilitating interaction with casein micelles and hydrocolloids to form a stable gel-like curd matrix.

[0246] Composition of Bioactive Output Components (Weight % of Final Product):

[0247] Calcium citrate: 0.5111% to 0.785%, Calcium fumarate: 0.1511% to 0.197%, Calcium malate: 0.00% to 0.1295% , Calcium chloride: 0.059% to 0.115%, Tri-calcium phosphate: 0.059% to 0.22% , Calcium propionate: 0.059% to 0.27%.

[0248] Bioactive Curd as a Calcium Supplement

[0249] The resultant bioactive curd is enriched with calcium citrate and elevated free Ca2+ions, providing enhanced calcium bioavailability and functional supplementation. This calcium form is especially effective due to its optimal absorption characteristics, particularly in acidic environments such as the stomach. Calcium citrate does not require additional stomach acid for absorption, permitting flexible consumption (even on an empty stomach).

[0250] Clinical literature supports that calcium citrate malate is absorbed approximately 4-5% better than calcium carbonate, regardless of food intake, and mitigates osteoporosis more effectively. Meta-analyses of clinical trials report calcium citrate absorption increase between 22% to 27% compared to calcium carbonate.

[0251] Therapeutic and Clinical Implications

[0252] Calcium citrate formulations are recommended in clinical guidelines for preventing calcium- containing kidney stones. They reduce stone recurrence and size relative to placebo controls.

[0253] Calcium citrate increases urinary citrate levels which bind urinary calcium, lowering insoluble calcium oxalate and phosphate crystal formation, the principal constituents of kidney stones.

[0254] Urine alkalinization by citrate creates an environment less hospitable to bacteria, thereby indirectly supporting urinary tract infection prevention.

[0255] Probiotic and calcium citrate interactions improve gel firmness in acid-coagulated curd, resulting in a stable matrix for fermentation and enhanced probiotic activity.

[0256] Probiotic strains found naturally in curd (e.g., Lactobacillus delbrueckii subsp.bulgaricus, Streptococcus thermophilus) thrive in the presence of calcium salts, improving acidification and flavour development. Co-administration of probiotics enhances gut microbiota balance, immune function nutrient metabolism, and inflammatory regulation synergistically with calcium citrate’s bioactivity.

[0257] Best Mode of Practice

[0258] The preferred embodiment comprises spray dried milk powder near 50% by weight, citric acid around 1%, and calcium carbonate near 0.3%, with hydrocolloids combined around 0.3%, in water content adjusted to approximately 65%. Reconstitution at room temperature ensures rapid lactose hydrolysis, efficient curd formation, and maximal bioactive salt and probiotic activity, yielding a superior curd beverage.

The total enzyme mix ranges from approximately 0.10% to 0.72% by weight of the total composition.

[0263] Biochemical Reactions and Process Description

[0264] 1.Acid-Base Neutralization:

[0265] Potassium bicarbonate and magnesium carbonate partially neutralize citric, fumaric, and phosphoric acids, resulting in formation of potassium, magnesium, and calcium salts (citrates, fumarates, phosphates) and evolution of carbon dioxide (CO2). This reaction facilitates powder dispersion and texture development.

[0266] 2. Acidification:

[0267] Phosphoric, citric, and fumaric acids reduce the solution pH to approximately 3.8-4.2, which is optimal for acid lactase enzyme activity and effective lactose hydrolysis.

[0268] 3.Gelation and Thickening:

[0269] Hydrocolloids — guar gum, pectin, xanthan gum, sodium alginate, and carboxymethyl cellulose — hydrate and interact to form a stable viscous matrix, improving curd texture and mouthfeel.

[0270] 4.Mineral Complexation:

[0271] Calcium and magnesium salts interact with hydrocolloids and milk proteins to stabilize gel formation, strengthen texture, and enhance nutritional value. 5.Lactose Hydrolysis:

[0272] Initial rapid acid-catalyzed lactose hydrolysis occurs, followed by enzymatic lactose breakdown that reduces lactose content without thermal degradation, increases bioactive peptide formation, and improves sensory and nutritional profiles.

[0273] Bioactive Components and Functional Advantages

[0274] Potassium citrate (BGCeHsO?): 0.45% to 0.55%, Magnesium fumarate (Mg(C4H4O4)): 0.15% to 0.20%, Calcium phosphate species (CaHPO4, Cas(PO4)2): 0.05% to 0.07% , Calcium citrate, Residual citric acid: 0.60% to 0.70% , Residual fumaric acid: 0.12% to 0.18% ,Free phosphoric acid: 0.35% to 0.40% , Hydrocolloids and calcium propionate forming gel network

[0275] These bioactive salts and organic acids regulate electrolyte balance, support kidney and bone health, enhance antioxidant activity, and inhibit pathogenic microbial growth, thereby improving metabolic, digestive, and cardiovascular health.

[0276] Best Mode

[0277] The preferred composition achieves a balanced pH of approximately 4 employing phosphoric acid for sustained acidification optimal for enzymatic activity. Co-additives such as datem, glycine, and vinyl alcohol (each in 0.10% to 0.15% range) enhance texture, stability, and flavor without impairing bioactivity.

[0278] This disclosure fully satisfies the written description by detailing composition and biochemical processes, enables one skilled in the art to prepare the formulation and practice lactose hydrolysis therein, and identifies the best mode known at the time of invention.

[0279] Example 4: Instant Curd Composition without Alkalizing / Buffering Agents

[0280] Spray dried agglomerated milk powder: 25% to 58.14% , Citric acid: 0.10% to 1.71%, Fumaric acid: 0.10% to 0.61%, Malic acid: 0.00% to 1.21%, Succinic acid: 0.00% to 0.61%, Calcium chloride: 0.01% to 0.16%, Tri-calcium phosphate: 0.01% to 0.16% ,Guar gum: 0.01% to 0.12%, Pectin: 0.01% to 0.12%, Xanthan gum: .01% to 0.12% , Sodium alginate: approximately 0.01% to 0.06%, Calcium propionate: 0.01% to 0.06% , Carboxymethyl cellulose (CMC): 0.01% to 0.12%,Seaweed:0.00% to 0.12%, Water: 0.20% to 89.6% Composition Ranges (by Weight): pH and Functional Overview:

[0281] The typical pH of the reconstituted mixture, composed of acids without neutralizing bases, is about 4.2. The acidity provided by citric and fumaric acids lowers the pH, inducing rapid curd formation and accelerating lactose hydrolysis. This composition is configured to produce bioactive components within the curd matrix that can potentially regulate or treat hypertension and manage diabetes.

[0282] Bioactive Components in Output Curd:

[0283] • A significant fraction of fumaric and citric acids remain free and partially protonated within the curd matrix, as they are largely unneutralized due to absence of neutralizing bases.

[0284] • Calcium citrate is formed via reaction of calcium ions from sources such as calcium chloride and tri-calcium phosphate with citrate ions, present in approximately 0.45% to 0.58% by weight.

[0285] • Guar gum, pectin, and xanthan gum remain chemically unreacted but physically hydrate to form a viscous gel matrix to stabilize the curd.

[0286] Approximate compositions within the curd include:

[0287] Citric acid -1.01%, Fumaric acid -0.31%, Guar gum -0.12%, Pectin -0.12%, Xanthan gum -0.12%

[0288] Role of Carboxylic Acid-Based Resins and Synergistic Effects:

[0289] Carboxylic acid-based resins can act as weak cation exchange resins facilitating lactose hydrolysis. The excess citric and fumaric acids in this formulation act as process optimizers beyond their acidification roles, catalyzing and complementing the lactose hydrolysis process. This synergy results in enhanced lactose breakdown, contrary to prior disregard of such acids as weak catalysts.

[0290] Health Benefits and Metabolic Effects:

[0291] • The bioactive curd formulation supports potential health benefits related to hypertension and diabetes regulation.

[0292] • Fumaric and citric acids have documented roles in blood pressure regulation, vascular function improvement, and metabolic health.

[0293] • Dietary hydrocolloids such as guar gum, pectin, xanthan gum, and seaweed function as fibers that improve glycemic control, insulin sensitivity, delay glucose absorption, and modulate gut microbiota, contributing positively to diabetes management.

[0294] • Clinical studies demonstrate that dairy products enriched with bioactive peptides and organic acids from such formulations improve glucose metabolism and blood pressure regulation.

[0295] • Fumaric acid shows anti-inflammatory activity in animal models, even at low doses. • Citric acid promotes calcium absorption, metabolic processes involving the citric acid cycle, endothelial function, and antioxidant activity by chelating pro-oxidant metals.

[0296] • Citric and malic acids have shown significant reduction in mean arterial blood pressure in rat models at tested doses.

[0297] Molecular Mechanism of Fumaric Acid:

[0298] • Fumaric acid inhibits TET (Ten-Eleven Translocation) enzymes by competing with their cofactor 2-oxoglutarate, reducing DNA demethylation necessary for gene regulation. This mechanism implicates fumaric acid in modulating pathways relevant to hypoxia and metabolic regulation. Experimental data reveals fumaric acid's potential in lowering blood pressure, reducing urinary protein, and managing placental edema, supporting its role in hypertension therapy. It may also contribute to epigenetic modifications affecting cancer and gestational hypertension cellular responses and mediate vasodilation via endogenous nitric oxide pathways.

[0299] Fiber Effects and Dosages:

[0300] • Dietary fibers such as guar gum, pectin, xanthan gum, and seaweed delay carbohydrate absorption, improve lipid profiles, support gut health, and regulate blood glucose, indirectly aiding hypertension and diabetes.

[0301] • Guar gum improves insulin sensitivity at dosages of 5-15 g / day and has been associated with reductions in postprandial hypotension and systolic blood pressure in clinical studies.

[0302] • Pectin supports lipid and glucose metabolism with similar effective dosage ranges.

[0303] • Seaweed has positive effects on regressive traits of diabetes.

[0304] • Suggested daily intake ranges for blood pressure regulation and overall metabolic benefits span 8-36 grams per day.

[0305] Formulation Fortification:

[0306] To meet functional dosage requirements per serving for hypertension and diabetes management, the bioactive curd may be fortified with additional amounts of:

[0307] Fumaric acid 0.36%, Citric acid 0.32%, Guar gum 3.20%, Pectin 3.20%, Xanthan gum 1.20%

[0313] Functional Description and Process

[0314] This composition yields a protein-rich, sweet curd with instant curd formation and rapid lactose hydrolysis occurring simultaneously. Protonation of lactose under acidic conditions achieves instant lactose split, facilitating sweet flavor development.

[0315] Upon reconstitution, the mixture may be further diluted or has additional hydrating medium added to produce beverages such as sweet lassi or salted buttermilk with consistent composition.

[0316] Protein Content and Carrier Functionality

[0317] The resultant curd inherently contains native milk proteins, including whey protein isolate and casein protein, serving as supplemental nutritional components. The formulation acts as an effective carrier of protein, capable of delivering an augmented protein load ranging from 0% to 30% by weight depending on the precise formulation selected.

[0318] Vending Machine Integration and Operation:

[0319] • The inventive vending machine features two sealed powder chambers, one housing the prosusceptised milk powder and the other containing the complementary premix as above.

[0320] • Each chamber is connected to an electronically controlled dispensing mechanism, which dispenses metered amounts of powders in proportions specific to the user's beverage selection (buttermilk, lassi, casein-based protein drink, whey-based protein drink, or blended options). • A controlled hydrating medium delivery system supplies precise water volumes to the mixing chamber for reconstitution, adjustable by drink type and user customization inputs (sweetness, viscosity, protein content).

[0321] • Inside the mixing chamber, an automated stirring mechanism mixes the powders and water to form a homogeneous curd beverage.

[0322] • The system includes a temperature regulation unit with heating elements and sensors maintaining beverage temperatures optimized for taste, consistency, and microbial safety (e.g., 4°C to 40°C depending on beverage).

[0323] • Users interact via a user interface allowing selection and customization of beverage parameters, which control dispensing ratios, hydration volume, and temperature settings.

[0324] • After preparation, the beverage is dispensed through a hygienic outlet designed to minimize contamination and enable easy cup placement and removal.

[0325] Biochemical and Functional Effects in Vending Operation:

[0326] • Following powder dispensing and hydration, acid-base reactions (e.g., citric acid with sodium bicarbonate) produce potassium citrate and magnesium citrate, aiding instant curd formation and bioactive salt generation.

[0327] • The low pH (-4.0-4.2) facilitates rapid lactose hydrolysis, increasing sweetness and digestibility.

[0328] • Hydrocolloids (guar gum, pectin, xanthan gum) hydrate and form viscous matrices contributing to texture and stability.

[0329] • Mineral salts (calcium chloride, tri-calcium phosphate, calcium propionate) reinforce the gel network and extend shelf life.

[0330] • Protein components from whey and casein powders enhance the nutritional profile, with the machine enabling adjustable protein concentration delivery.

[0331] This detailed example enables one skilled in the art to implement the claimed vending machine for instant curd-based beverage dispensing with customizable beverage properties, while assuring consistency, taste, freshness, and bioactivity, fulfilling USPTO and UK patent specification requirements including written description, enablement, and best mode.
