Development and characterization of microencapsulated Pichia kluyveri CCMA 0615 with probiotic properties and its application in fermented beverages

The study aimed to develop innovative microencapsulated formulations of strains with probiotic attributes, Pichia kluyveri CCMA 0615 and Saccharomyces cerevisiae CCMA 0732. The yeasts (8 log CFU/mL) were microencapsulated by spray drying technique using whey powder (WP - 15 %, 20 %, and 30 %) and sodium alginate (ALG - 1 %). The microcapsules and cell viability were characterized during two months of storage (4 °C and 25 °C). The selected formulations were applied to functional beverage fermentation, and viability and survival in the simulated gastrointestinal tract (GIT) were performed. The viability of yeasts microencapsulated by the spray drying method was shown to be dependent on the strain and encapsulating matrix used, ranging from 84 to 99 %. P. kluyveri required refrigeration when storing microcapsules. In functional beverage fermentation, microencapsulated yeast maintained the same fermentative profile with carbohydrate consumption, production of lactic acid (0.30 to 1.10 g/L) and alcohol (0.2 to 1.61 g/L), and greater viability during storage. Finally, the microencapsulation of P. kluyveri with 15 % WP + 1 % ALG maintained high viability under GIT conditions, whether exposed independently (>84 %) or incorporated into a food matrix (>94 %). The study demonstrated that this innovative microencapsulation of probiotic yeasts increases their viability, improves biotechnological application, and facilitates efficient delivery of probiotics to the host.

Regulation on Aggregation Behavior and In Vitro Digestibility of Phytic Acid–Whey Protein Isolate Complexes: Effects of Heating, pH and Phytic Acid Levels

The impact of heat treatment, pH and phytic acid (PA) concentration on the aggregation behavior and digestibility of whey protein isolate (WPI) was investigated. The experimental results indicated that below the isoelectric point of WPI, heat treatment and elevated PA levels significantly increased turbidity and particle size, leading to the aggregation of WPI molecules. No new chemical bonds were formed and the thermodynamic parameters ΔH < 0, ΔS > 0 and ΔG < 0 suggested that the interaction between PA and WPI was primarily a spontaneous electrostatic interaction driven by enthalpy. After the small intestine stage, increasing phytic acid levels resulted in a significant decrease in hydrolysis degree from 16.2 ± 1.5% (PA0) to 10.9 ± 1.4% (0.5% PA). Conversely, above isoelectric point of WPI, there was no significant correlation between the presence of PA and the aggregation behavior or digestion characteristics of WPI. These results were attributed to steric hindrance caused by PA-WPI condensates, which prevented protease binding to hydrolysis sites on WPI. In summary, the effect of PA on protein aggregation behavior and digestive characteristics was not simply dependent on its presence but largely on the aggregation degree of PA-WPI induced by heat treatment, pH and PA concentration. The findings obtained here suggested that phytic acid may be utilized as an agent to modulate the digestion characteristics of proteins according to production requirements. Additionally, the agglomerates formed by heating phytic acid and protein below the isoelectric point could also be utilized for nutrient delivery.

Assessment of sweet whey fortified with Bifidobacteria and selenium on reduction of pesticide liver toxicity in albino rats

Deltamethrin (DLM) represents one of the most commonly used pesticides. It passes through milk, vegetables, and fruits to humans or through animals (veterinary drugs and feeding on contaminated forage) to milk; it can escape from skin to blood and be secreted in breast milk in lactating women. It is believed to have neurotoxic, nephrotoxic, and hepatotoxic properties. To investigate deltamethrin-induced hepatotoxicity, 64 rats were divided into eight groups. The control group did not receive any treatment. The groups were as follows: D 30 mg DLM/kg body weight (BW) dissolved in corn oil; B 1 mL whey (1010 cfu/mL of Bifidobacterium longum ATCC 15707); S 1 mL whey (0.5 ppm selenium); BS 1 mL whey (1010 cfu/mL of B. longum ATCC 15707 + 0.5 ppm selenium); BD 1 mL whey (1010 cfu/mL of B. longum ATCC 15707 + DLM); SD 1 mL whey (0.5 ppm selenium) + DLM; and BSD 1 mL whey (1010 cfu/mL of B. longum ATCC 15707) + 0.5 ppm selenium + DLM. Results revealed that the manipulation of Bifidobacteria with selenium triggered a significant improvement in AST (U/mL), ALT (U/mL), GSH (mg/g), TNF-α (pg/mL), NF-κB (ng/mL), and BCL2 (ng/mL) from 166.7 ± 6.42, 30.67 ± 0.55, 0.252 ± 0.005, 17.18 ± 0.42, 1.14 ± 0.10, and 1.77 ± 0.06 versus 334.9 ± 4.7, 72.83 ± 2.49, 0.108 ± 0.005, 33.57 ± 0.59, 2.58 ± 0.05, and 1.04 ± 0.04, respectively, compared to DLM group. As well as reduction in histopathological necrosis, congestion, and degradation. Whey beverages fortified with B. longum and selenium implicated a reduction in oxidative stress and histopathological degradation that accomplished DLM toxicity. The utilization of whey (a byproduct of cheese making) is considered a recycling process that supports eco-friendly practices and sustainability, thus encouraging its use as a protective tool in animal feed or manipulation by humans, especially workers in pesticide plants.

Comparison of Whey N-Glycoproteins in Yak Colostrum and Mature Milk Based on 4D Label-Free Technology.

Whey proteins are N-glycosylated proteins that play important roles in a variety of biological processes including immune defense. However, the N-glycosylation of yak colostrum (YC) and mature milk (YM) whey proteins is unknown. Therefore, this study systematically compared and analyzed YC and YM whey N-glycoproteomes using the 4D label-free technique. We identified 162 glycoproteins, 222 glycosylated peptides, and 234 glycosylation sites in YC and YM, of which 59 glycoproteins were differentially expressed in YC and YM. According to gene ontology annotation and KEGG pathway metabolism analysis, the differentially expressed N-glycoproteins were highly enriched in "cell adhesion", "extracellular region", and "calcium binding", and were mainly involved in the extracellular matrix (ECM)-receptor interaction pathway. The immunity-related N-glycoproteins, such as platelet glycoprotein 4 (CD36) and polymeric immunoglobulin receptor (PIGR), were observed to be different between YC and YM. The results revealed the glycosylation sites, composition, and biological functions of YC and YM whey N-glycoprotein, which supplemented our understanding of the N-glycosylation of yak whey proteins.

By-Products Valorization: Peptide Fractions from Milk Permeate Exert Antioxidant Activity in Cellular and In Vivo Models.

The discarding of agri-food by-products is a stringent problem due to their high environmental impact. Recovery strategies can lead to a reduction of waste and result in new applications. Agri-food waste represents a source of bioactive molecules, which could promote health benefits. The primary goal of this research has been the assessment of the antioxidant activity of milk permeate, a dairy farm by-product, and the isolation and identification of peptide fractions endowed with antioxidant activity. The chromatographic extraction of the peptide fractions was carried out, and the peptides were identified by mass spectrometry. The fractions showed radical scavenging activity in vitro. Moreover, the results in the Caco-2 cell model demonstrated that the peptide fractions were able to protect from oxidative stress by stimulating the Keap1/Nrf2 antioxidant signaling pathway, increasing the transcription of antioxidant enzymes. In addition, the bioactive peptides can affect cellular metabolism, increasing mitochondrial respiration. The action of the peptide fractions was also assessed in vivo on a zebrafish model and resulted in the protection of the whole organism from the adverse effects of acute cold stress, highlighting their strong capability to protect from an oxidative insult. Altogether, the results unveil novel recovery strategies for food by-products as sources of antioxidant bioactive peptides that might be utilized for the development of functional foods.

Exploring the Potential of Kishk-like Novel Product in Solving the Acidic Whey Conundrum in the Dairy Industry

Acidic whey, unlike sweet whey, poses significant environmental challenges in the dairy industry. The Lebanese population consumes large quantities of labneh (strained yogurt) and white cheese, resulting in substantial acidic whey production, which presents disposal issues and pollution risks. Kishk, a fermented-milk cereal mixture, has a characteristic acidic taste. This study developed a Kishk-Like product using concentrated acidic whey as a substitute for fermented milk, addressing the disposal problem while enhancing dairy industry profitability. This study was conducted from April to June 2023. As consumer acceptance is the first step in food product development, a triangle sensory test was performed three times with 30 panelists each time, who attempted to differentiate between an established fermented cow’s milk kishk (CMK) and the new Kishk-Like product (KLP) made with three-fold concentrated acidic whey. In the three runs, 11, 9 and 13 out of 30 panelists were able to differentiate between the CMK and KLP samples, yielding p-values of 0.415, 0.713 and 0.166, respectively. These findings, coupled with the fact that approximately 12 kg of acidic whey is required to produce 1 kg of KLP, highlight its potential as a straightforward, economically viable solution for the acidic whey disposal dilemma, warranting further research into its development, characterization and standardization.

Investigating the effect of whey and casein proteins on drug solubility from a paediatric drug absorption perspective

Considering the predominantly milk-based diet of neonates and infants and their immature gastrointestinal digestion, milk proteins may affect drug behaviour and absorption in this population. Using in vitro models, this study investigated the impact of the representative milk proteins, whey and casein, on the solubility and permeation of the lipophilic model drugs spironolactone, clopidogrel and ritonavir. Drug solubility experiments revealed that the presence of milk proteins increased drug solubility. Next, permeation studies demonstrated that the same milk proteins reduced drug permeation across an artificial membrane. These results highlight the importance of the solubility-permeability interplay and indicate the effect of these proteins may be considered during (paediatric) drug development. Lastly, the findings underscore the importance of considering milk protein-drug interactions to optimize drug delivery strategies during (paediatric) drug development and especially for the youngest and most vulnerable part of this population.

Production of α-ketoisovalerate with whey powder by systemic metabolic engineering of Klebsiella oxytoca

BackgroundWhey, which has high biochemical oxygen demand and chemical oxygen demand, is mass-produced as a major by-product of the dairying industry. Microbial fermentation using whey as the carbon source may convert this potential pollutant into value-added products. This study investigated the potential of using whey powder to produce α-ketoisovalerate, an important platform chemical.ResultsKlebsiella oxytoca VKO-9, an efficient L-valine producing strain belonging to Risk Group 1 organism, was selected for the production of α-ketoisovalerate. The leucine dehydrogenase and branched-chain α-keto acid dehydrogenase, which catalyzed the reductive amination and oxidative decarboxylation of α-ketoisovalerate, respectively, were inactivated to enhance the accumulation of α-ketoisovalerate. The production of α-ketoisovalerate was also improved through overexpressing α-acetolactate synthase responsible for pyruvate polymerization and mutant acetohydroxyacid isomeroreductase related to α-acetolactate reduction. The obtained strain K. oxytoca KIV-7 produced 37.3 g/L of α-ketoisovalerate from lactose, the major utilizable carbohydrate in whey. In addition, K. oxytoca KIV-7 also produced α-ketoisovalerate from whey powder with a concentration of 40.7 g/L and a yield of 0.418 g/g.ConclusionThe process introduced in this study enabled efficient α-ketoisovalerate production from low-cost substrate whey powder. Since the key genes for α-ketoisovalerate generation were integrated in genome of K. oxytoca KIV-7 and constitutively expressed, this strain is promising in stable α-ketoisovalerate fermentation and can be used as a chassis strain for α-ketoisovalerate derivatives production.

Influence of β-lactoglobulin and κ-casein genotype on whey protein denaturation in heated bovine milk and rennet whey

Whey proteins provide nutritional and functional properties in many dairy products, and their denaturation induced by heat has drawn attention in dairy research and industry. Denatured whey proteins have functional properties that are beneficial for certain applications, such as yogurt, while uncontrolled denatured protein aggregation can impair certain processes, such as rennet coagulation. The possible effect of genetic polymorphism of β-lg and κ-CN on heat-induced denaturation of whey proteins in milk and in rennet whey was investigated in this study. No effect of κ-CN genotype on the denaturation of β-lg and α-lac was detected, while the A variant of β-lg was more heat-stable than the B variant. More denatured β-lg B was shown to interact with casein micelles to form insoluble aggregates compared to the A variant. These results may provide guidance for selection of specific milk genotypes for applications where whey protein denaturation needs to be minimised or else preferred, such as foaming and emulsification.

Assessment of the impact of pasteurisation on protein denaturation in sheep sweet whey by asymmetrical flow field-flow fractionation according to sampling period

Whey recovery is limited in artisanal cheese manufacture. This by-product of cheese manufacture was traditionally considered as waste and is highly polluting. However, interest in the nutritional properties of native whey and its proteins has recently increased. Pretreatment is required to preserve highly perishable whey for processing. Only a few studies have focused on sheep whey, despite its considerable nutritional and technological potential. Here, we investigated the effect of heat treatment on the denaturation and formation of protein aggregates in sweet sheep whey collected in January, April and July. Two pasteurisation protocols were studied (72 °C for 1 min and 80 °C for 15 s). Microbiological quality was assessed by checking for the presence of microbes after five days of storage at 4 °C. Asymmetrical flow field-flow fractionation (AF4) coupled to UV detector, multiangle light scattering (MALS) and refractometer (dRi) is a mild, non-naturing technique for determining the extent of denaturation of whey proteins and the size of whey protein aggregates. Greater whey protein denaturation and larger whey protein aggregates were observed for the 80 °C/15 s protocol than for the 72 °C/1 min protocol, for the January and April samples. A decrease in Immunoglobulin G (IgG) content was observed after heat treatments in the samples from July but not significantly for the other proteins. Moreover, the retention times of the monomeric whey protein peaks on the AF4 fractogram were higher for this period, indicating that the proteins were larger. Microbiological testing showed that both pasteurisation treatments were sufficiently effective to ensure good sanitary quality. The pasteurisation schedule best preserving native proteins was heating at 72 °C for 1 min.

Effects of spray drying and freeze drying on the protein profile of whey protein concentrate.

Whey protein concentrate (WPC) is consumed for its high protein content. The structure and biological functionality of whey proteins in WPC powders may be affected by the drying technique applied. However, the specific impact of spray drying and freeze drying on the overall protein profile of whey protein derived from sweet whey streams at scale is unknown. Herein, we examine the effects of commercial-scale freeze drying and spray drying on WPC to determine which method better preserves bioactive whey proteins, with the goal of helping the dairy industry create high-value products that meet the growing consumer demand for functional dairy products. WPCs were produced from pasteurized liquid whey using either a commercial spray dryer or freeze dryer. A variety of analytical techniques, including enzyme-linked immunosorbent assay, polyacrylamide gel electrophoresis, and bottom-up proteomics using liquid chromatography-tandem mass spectroscopy were used to identify, quantify, and compare the retention of bioactive proteins in WPC before and after spray drying and freeze drying. In addition, the extent of denaturation was studied via solubility testing, differential scanning calorimetry, and hydrophobicity assessment. There was little to no difference in the retention or denaturation of key bioactive proteins between spray-dried and freeze-dried WPC powders. There was a higher percentage of select Maillard modifications in freeze-dried and spray-dried powders than in the control. The lack of significant differences between spray drying and freeze drying identified herein indicates that freeze drying does not meaningfully improve retention of bioactive proteins compared with spray drying when performed after multiple pasteurization steps. PRACTICAL APPLICATION: This study aimed to provide insight into the impacts of spray drying versus freeze drying on whey proteins. Overall, our results indicate that for commercial dairy processing that involves multiple rounds of pasteurization, freeze drying does not meaningfully improve the retention of bioactive proteins compared with spray drying. These findings may help the food and dairy industry make informed decisions regarding the processing of its whey protein products to optimize nutritional value.

Polyhydroxybutyrate production from non-recyclable fiber rejects and acid whey as mixed substrate by recombinant Escherichia coli

Producing polyhydroxybutyrate (PHB) from agro-food processing waste has the potential to mitigate the global synthetic plastic pollution crisis and reduce greenhouse gas emissions. Additionally, it offers a promising solution to the challenges associated with high feedstock and production costs. This study aims to explore the use of two such wastes, non-recyclable fiber rejects (FR) (solid waste) and acid whey (AW) (liquid waste), as cost-effective and sustainable carbon sources for PHB production. Fiber rejects contains up to 50% carbohydrates that can be hydrolyzed to fermentable sugars. The AW is composed of lactose, lactic acid, fats, proteins, and mineral salts which could be used as carbon sources for PHB. The focus of this work was a comprehensive evaluation of substrate utilization, cell growth, and PHB inclusion in recombinant E. coli during the fermentation of various blends of acid whey and hydrolysate obtained from fiber rejects. Two approaches were investigated: i) produce FR hydrolysate and mix it with AW in various ratios (1:2, 1:1, and 2:1), and ii) use acid whey to replace water during the hydrolysis of FR. Combining acid whey with the hydrolysate achieved the highest PHB yield in a shorter duration compared to using only the hydrolysate. Replacing acid whey with water during the enzymatic hydrolysis of pretreated fiber rejects and utilizing it further for fermentation resulted in the highest PHB yield of 5.2 g/L, with a 45.4% PHB inclusion rate. Additionally, the inherent lactic acid content in acid whey eliminates the need for adding acetic acid to adjust pH levels during hydrolysis, thereby saving freshwater and acid.Graphical

Short communication: Evaluation of spore-former presence in caseinate, cheese and whey powders

This study examined spore-former presence in imported caseinate and the cheese in which it is used as an additive, as well as commercial powders produced from cheese whey (whey protein concentrate-80 (WPC-80) and permeate powder). A single batch of imported caseinate, and the cheese it was utilized in, was collected 11 times over a 16-month period. In addition, samples of commercially produced whey powder were collected over a period of 23 months. Spore-formers were detected using enrichment with reinforced clostridium medium (RCM) in anaerobic conditions and microbiota was analyzed by amplicon sequencing. Gas production was observed in all caseinate samples, with 23 isolates from six known spore-former species identified via matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF). No gas was detected in any of the enriched tubes of the cheese or whey powder samples. We also applied culture-independent analysis to assess microbial diversity and detect spore-formers not identified with the culture-dependent method. Altogether, the results of this study will contribute to the knowledge of spore-former presence and transfer between different dairy products, facilitating targeted actions to reduce quality problems.

Decontamination of Biological Agents in Wastewater through Synergetic Oxidative Methods as an Effective Approach for Safeguarding Public Health and Aquatic Ecosystems

We employed a highly concentrated model of wastewater to conduct our research, accurately mimicking the composition of wastewater generated by milk processing enterprises. Wastewater contained milk protein, carbohydrates, and whey sugars. Domestic wastewater, which served as a source of indicator fecal microorganisms, was added to them. The water purification and disinfection scheme involved treating a model wastewater using the biosorption method with an immobilized biocenosis in a laboratory installation, followed by further purification and disinfection in a decontamination tank. In comparison, we assessed the degree of microorganism elimination using distinct methods such as ozonation, hydrogen peroxide treatment, and combination of О3/Н2О2. It has been demonstrated that model wastewater, purified and disinfected using the AOPs method, also contains dissolved oxygen, which is non-toxic to aquatic microbiota.

Two major bovine milk whey proteins induce distinct responses in IEC-6 intestinal cells

Abstract α-Lactalbumin (α-LA) and β-lactoglobulin (β-LG) are major whey proteins in bovine milk. We studied the effects of these molecules on the intestinal cell response by comparing the native form with the denatured form containing oligomers obtained by treatment with 2,2,2-trifluoroethanol (TFE). We previously reported that proteins in native and TFE-treated forms exhibited cell growth stimulation and cytotoxicity, respectively, in undifferentiated rat crypt IEC-6 and human colon Caco-2 cells. However, neither whey protein showed cytotoxicity even in the TFE-treated form in differentiated Caco-2 cells. Only undifferentiated immature intestinal cells can distinguish between these native and denatured proteins. Moreover, α-LA and β-LG exhibited different oligomer formation characteristics during the TFE treatment. In the present study, we compared the effects of native and TFE-treated whey proteins on IEC-6 cells in more detail. The native forms of both whey proteins exhibited cell proliferative effects in a concentration-dependent manner. For the TFE-treated forms, α-LA showed rapid and potent cytotoxicity, whereas β-LG altered cell responses depending on its concentration and exposure time; lower concentration/shorter exposure and higher concentration/longer exposure induced cell growth stimulation and cytotoxicity, respectively. Pre-treatment of the cell membrane with cholesterol suppressed the effects on the cell response only in TFE-treated β-LG (TFE-β-LG). In a preliminary examination using inhibitors of signal transduction, TFE-treated α-LA acted on the intrinsic apoptosis pathway via Bcl-2-associated X and p53, whereas the action of TFE-LG did not require this pathway. Tyrosine phosphorylation is necessary for the cell proliferation effect of both native whey proteins; however, native α-LA, but not native β-LG, also required activation of the pathway with selective epidermal growth factor receptor tyrosine kinase and Janus kinase 2/3. In summary, the two major bovine milk whey proteins induced similar yet discrete responses in undifferentiated intestinal cells. Even when oligomers are formed, β-LG may be much less hazardous to immature intestinal cells than α-LA.

Characteristics of a Spray-Dried Porcine Blood Meal for Aedes aegypti Mosquitoes.

Research into mosquito-borne illnesses faces hurdles because feeding fresh animal blood to rear female mosquitoes presents logistical, economic, and safety challenges. In this study, a shelf-stable additive (spray-dried porcine blood; SDPB) hypothesized to supply accessible hemoglobin was evaluated within an alternative meal (AM) containing whey powder and PBS for rearing the yellow fever mosquito Aedes aegypti. LC-MS/MS proteomics, microbial assays, and particle reduction techniques confirmed and characterized the functionality of hemoglobin in SDPB, while engorgement, fecundity, egg viability, and meal stability bioassays assessed AM performance. Chemical assays supported hemoglobin as the phagostimulant in SDPB with aggregates partially solubilized in the AM that can be more accessible via particle reduction. Unpaired two-tailed t-tests indicate that the AM stimulates oogenesis (t11 = 13.6, p = 0.003) and is stable under ambient (1+ y; t12 = 0.576, p = 0.575) and aqueous (14 d; t12 = 0.515, p = 0.639) conditions without decreasing fecundity. Egg hatch rates for the ninth generation of AM-reared Ae. aegypti were 50-70+%. With further development, this meal may serve as a platform for mass rearing or studying effects of nutritional additives on mosquito fitness due to its low cost and stability. Future work may examine tuning spray drying parameters and resulting impacts on hemoglobin agglomeration and feeding.

Yogurt acid whey powder dietary inclusion level modulates broiler cecal microbiota composition and metabolic activity

All over the world, the increasing demand for Greek yogurt generates vast quantities of acid whey as a by-product. The large volume and nutrient composition of yogurt acid whey makes it worthwhile to investigate potential uses in animal nutrition. This study aimed to investigate the inclusion of yogurt acid whey powder (YAWP) in four dietary levels on broiler performance, cecal microbiota composition and metabolic activity. A total of 300 male one-day-old male Ross broiler chickens were randomly assigned into 4 treatments of 5 replicates each. Broilers were fed maize-soybean meal basal diets following a 2-phase feeding program. Depending on the YAWP inclusion level (g kg-1 diet), treatments were no YAWP addition (W0), YAWP at 25 g kg-1 (W25), YAWP at 50 g kg-1 (W50) and YAWP at 100 g kg-1 (W100). Overall body weight gain, feed intake and feed conversion ratio were not affected by YAWP addition. In the ceca, a linear decrease in total bacteria counts and a linear increase in Lactobacillus spp. was noted with increasing YAWP dietary level. A linear reduction of Clostridium cluster I and E. coli species was noted with increasing YAWP dietary level. A linear increase in total volatile fatty acids concentration, acetic acid and butyric acid molar ratios was shown with increasing YAWP level. In conclusion, the addition of YAWP did not affect overall performance but positively modulated the cecal microbiota and metabolic activity of 42-day-old broiler chickens.

Functional whey-based drinks with grape pomace extract and fruit juice

Industrial waste leads to pollution and deterioration of the environment, as well as harming the living population and animals. Whey, being a by-product of milk processing, is a source of protein and nitrogenous compounds, carbohydrates, lipids, mineral supplements, vitamins, organic acids, enzymes and macro- and microelements. Amino acid content of whey is represented by amino acids of protein substances and free amino acids. The next valuable secondary raw material is grape pomace, which is practically not processed and becomes a factor of anthropogenic load, polluting the environment. Grape pomace has a rich chemical composition, especially a large number of phenolic compounds, which have antioxidant properties. Currently, there is a significant increase in the production and consumption of soft drinks with various additives, the composition of which is replete with unnecessary colors and flavors. The aim of the work is to use milk whey for the development of technology of drinks of functional purpose, which will directly increase the efficiency of its processing, as a secondary raw material in industrial production, as well as serve the purpose of improving the environmental situation in places where milk processing plants are located. In particular, the creation of functional drinks on the basis of milk whey with the addition of grape pomace, fruit juices and pectin, will enrich the milk drink with a complex of biologically active substances, trace elements, antioxidants, vitamins. Using organoleptic and physico-chemical parameters, two technologies of functional drinks based on milk whey with 25% Husein Black grape pomace extract, in the first 25% cherry and in the second 25% peach juices were developed. The first formulation demonstrated noteworthy macro- and microelement content, including calcium (12.10%), sodium (5.04%), magnesium (1.60%), phosphorus (7.31%), and potassium (24.61%). Similarly, the second formulation exhibited significant macro- and microelement composition, including calcium (9.50%), sodium (4.28%), magnesium (1.33%), phosphorus (6.37%), and potassium (21.91%). All microbiological indicators meet the requirements of GOST and indicate the absence of pathogenic microflora, which is one of the indicators of guaranteed sanitary well-being of the proposed products. The developed drinks have pleasant organoleptic indicators, high biological value and low cost price.
