Prospects for the use of new yeast strains in non-alcoholic beer production
Статья научная
Brewery production is currently one of the growing segments of the processing industry. Beer and beer drinks have long established themselves as competitive products in the beverage production market. Modern beer producers focus on creating traditional light and dark beers, birmix, and beer drinks with various fruit flavours. They also place particular importance on producing non-alcoholic beer. The increase in demand for non-alcoholic beer is due to the partial transition to proper nutrition, the expansion of the assortment and the appearance of new flavours on the shelves. Non-alcoholic beer is a foamy beverage prepared according to classical beer production technology but with technological solutions for removing ethyl alcohol at the output. For the production of non-alcoholic beer, the permissible concentration of ethyl alcohol, which does not exceed 0.5%, is used. Vacuum distillation and membrane methods are used, and alcohol is removed by influencing the course of the technological process. One of these methods is the use of unique yeast strains in fermentation. The purpose of the presented research is to select new yeast strains for producing non-alcoholic beer. Four yeast strains were studied to determine their degree of digestion and influence on the profile of the finished beer. It was determined that yeast strain W 34/70 has the lowest degree of digestion. By technological and physicochemical parameters, the beer wort fermented by this yeast strain has suitable sensory parameters, which are not inferior to the production sample. The use of yeast strain W 34/70 also reduces the fermentation process and increases the shelf life of the finished beverage.

Proteolytic enzymes for improving the properties of meat products from non-traditional raw materials
Статья научная
In this scientific article the influence of enzymatic treatment on the quality of meat products from nontraditional raw materials (camelina, horse meat, mutton, beef) was studied. Bromelain (0.5-0.2%), papain (0.1-0.3%) and ficin (0.1-0.5%) as well as their combination were used as enzymes. To improve functional and technological characteristics, a multicomponent brine containing plant components (sea buckthorn powder, pumpkin powder and goji berry extract, rosemary extract), plant enzymes, phosphates and protein hydrolysates were used. The results showed that the use of enzymes contributed to the softening of the meat structure, improving the juiciness and tenderness of the product. The most pronounced effect was observed in samples treated with papain, while ficin had the greatest effect on mutton and beef. The study of pH dynamics showed that without enzyme treatment, pH increased to 6.67 after 5 days, indicating initial signs of spoilage. At the same time, the combined application of enzymes kept the pH at a stable level (6.20), which helped to extend the shelf life of the product. Thus, the use of proteolytic enzymes in combination with multicomponent brine improves the texture, organoleptic characteristics and functional and technological properties of meat products, which can be recommended for industrial production.

Quality and quantitative traits of non-alcoholic beer with flavor-improved taste
Статья научная
The non-alcoholic and low-alcohol beer market has grown significantly in recent years and is predicted to continue growing. However, non-alcoholic and low-alcohol beers have organoleptic problems and are not recognized by many consumers. The increasing popularity of alcohol-free beers (AFBs) fosters the industry's interest in delivering the best possible product. Yet, a remaining sensory issue of AFBs is the over-perception of wort flavor, caused by elevated concentrations of small volatile flavor compounds (i.e.aldehydes)still remains. Previously, molecular sieves (hydrophobic ZSM-5 type zeolites) were found as most suitable to remove these flavors by adsorption with high selectivity from the AFBs. In this work, a flavor-improved beer is produced at a pilot-scale using this novel technology, and its chemical composition, sensory profile, and stability are evaluated against a reference. Aldehyde concentrations in the flavor-improved product were found 79-93% lower than in the reference. The distinct difference was confirmed with a trained sensory panel and could be conserved even after three months of ageing at 30ºC. Future work will focus on the process design to scale up this technology. It is established that the release of a new kind of beer is economically profitable, since the expansion of the range contributes to a more complete use of production capacity, and consequently, reduced costs per unit of production, which ultimately leads to an increase in the profit of the enterprise.

Rational use of oil crops waste in feed production
Статья научная
Currently, at the stage of the country's economic development, in order for the agricultural sector to become profitable, competitive, and also ensure long-term independence, it must be productive. In this regard, it is necessary to use agricultural waste to increase productivity and the raw material base of feed production and improve quality. Such agricultural waste includes post–harvest waste from oilseeds, which are rich in minerals, micro-, macronutrients, protein, fat, fiber and vitamins. The use of post-harvest waste from oilseeds in the production of compound feeds is economically feasible. However, fulfilling this condition in industrial livestock farming requires large financial resources, which are not always recouped by the products produced. The way out of this situation is to replace expensive components with plant energy-protein components. During the study, a recipe for compound feeds with the introduction of post-harvest waste of oil crops was developed. Also, quality indicators such as crude protein, digestible protein, fat, fiber, and feed unit were studied. It was found that when introducing feed flour from post-harvest waste in the amount of sunflower -5%, safflower -2% into compound feeds, the quality indicators did not show any visible changes. With an increase in the rate of introduction of feed flour into compound feeds, the quality indicators increased. Thus, the introduction of waste-free technologies for the production of oilseeds with the development of products suitable for inclusion in compound feed will significantly expand the raw material base for compound feed production.

Статья научная
As you know, mare's milk is used for the prevention of lung diseases, as well as for the treatment of gastrointestinal diseases to restore the disturbed intestinal microflora. In this regard, it is especially important to preserve the physico-chemical characteristics of mare's milk during its storage before processing. The paper presents the results of studies of the technological characteristics of mare's milk produced in four peasant and farm farms of the Almaty region according to the seasons of the year. It is known that, having a high biological value, mare's milk, among other types of milk of farm animals, is the most suitable raw material in the production of dairy products for baby and dietary nutrition. Low fat and protein content, as well as high lactose content are distinctive characteristics of mare's milk. However, their content depends on the feeding conditions, breed and age, geographical location. It was found that the mass fraction of fat ranges from 1.2 % to 2.8 %, the mass fraction of protein was 2.0-2.36 %, SOMO - 8.35-8.73 %. Fluctuations in the quality indicators of mare's milk are explained by the influence of the season of the year, feeding and maintenance in various peasant and farm farms.

Study of the effect of probiotics on the shelf life of chilled broiler meat
Статья научная
Poultry meat can be contaminated with a wide range of microorganisms, including those that can spoil the product during chill storage and certain foodborne pathogens. This study aims to investigate the effect of probiotics on the shelf life of shilled broiler meat. The object of the study was fresh broiler meat obtained from broiler chickens fed three different amounts of probiotics, which were isolated from shubat and koumiss. For the control group, birds were fed a basal diet (BD) and drinking water (DW). Chicks in the experimental groups were fed by BD, DW, and probiotics 0.25 mL, 0.5 mL, and 1.0 mL per bird (groups Pro1, Pro2, and Pro3, respectively), for 42 days. Following slaughter, the filets were packed aerobically and stored in temperature-controlled conditions at 4±2ºC. Microbial examinations of meat quality included QMAFAnM, BGKP, pathogenic (Salmonella, Listeria monocytogenes), yeast, and mold. The sensory parameters were used to determine the meat samples' shelf life. Broiler filets had a sensory shelf life of 7 to 9 days. The novelty of this study lies in its focus on the use of probiotics in broiler meat, particularly in the context of Kazakhstan. While probiotics have been studied in a variety of food products, their effect on broiler meat in Kazakhstan has yet to be investigated. As per our results, we can recommend the application of the Pro2 level for the best shelf life, microbial quality, and sensory properties.

Study of the effect of the fermentation process on the biochemical characteristics of Vigna radiata
Статья научная
This article provides a comparative assessment of the chemical composition, the content of vitamins, minerals and amino acid composition of ordinary and fermented mung bean seeds, Vigna radiata. The seeds of Vigna radiata of the domestic selection "Zhasyl Dan" are the object of research. In order to increase the biological values of Vigna radiata seeds and improve their biochemical composition, a fermentation process was carried out. The effect of the fermentation process on the biochemical and amino acid composition of Vigna radiata seeds was studied. The fermentation process of mung bean seeds occurs due to the activation of a number of biochemical compounds and enzymes contained in the seed itself. The main substances that participate in and influence fermentation are amylases, proteases, lipases, gibberellins and other phytohormones such as auxins and cytokinins, polyphenols and antioxidants. Fermentation of Vigna radiata seeds was carried out at room temperature 200 C for 72 hours. The seeds were placed in a plastic container, then covered with drinking water also at room temperature. The water level was monitored every 12 hours. The research was carried out in the accredited testing laboratory "Regional Testing Laboratory of Engineering profile "Structural and Biochemical Materials" on the basis of M. Auezov South Kazakhstan University, Shymkent. As a result of the study, it was found that fermentation of Vigna radiata seeds leads to an improvement in physico-chemical properties. This is due to the strengthening of the amino acid composition of the Vigna radiata seed, especially the effect of fermentation has a positive effect on essential amino acids. It was found that as a result of fermentation, the level of essential amino acids increased in the following order: valine - by 25.4%, leucine - by 32.8%, phenylalanine - by 27.7%, threonine - by 44.9%. There was also a decrease in the indicators of anti-nutritional substances - in particular, there was a decrease in the amount of oligosaccharides. Due to the activation of the enzyme systems of the seed itself, their nutritional and biological value increases.

Study of urease activity in semi-finished meat products
Статья научная
Meat production is one of the fastest growing sectors of global agriculture, and poultry meat is the most accessible and expanding source of protein for people of all income levels. In connection with recent world events, such as the coronavirus pandemic, and considering its consequences, the issue of safety of "accessible" foodstuffs, among which poultry meat occupies a worthy place, is acute. For Kazakhstan, as well as for all countries, it is important to expand the range of food products that can significantly increase the immunity of the population to successfully overcome the consequences of the COVID 19 pandemic. Development of local poultry farming and import substitution are the main solutions to ensure product safety in any state. For effective development of poultry farming it is necessary to overcome one of the limiting factors - lack of modern system of safety monitoring throughout the food chain. The purpose of this work is to study the urease activity in meat semi-finished products. In this study urease activity was measured in raw and cooked meat products. As a result of the study the dependence of heat treatment with the pH index was determined. The indicator of urease activity during production allows for more detailed safety and quality assurance of meat semi-finished products.

In the Republic of Kazakhstan, pressing of flax seeds (squeezing) is most often used, therefore cake is more common than meal and its resulting physical reserves exceed meal several times. The biochemical characteristics of the protein complex of flaxseed have not been sufficiently studied, which, in our opinion, limits the use of protein products obtained from flax seeds such as flaxseed cake in the production of compound feed for farm animals and poultry. The article presents studies of the protein complex and amino acid composition of flaxseed cake of the Kazakhstan variety “Kostanay 11”. Flaxseed cake contains 36,5% protein, the fat content is 7,5%. The fractional composition of flaxseed cake was compared with the flax varieties “Northern” and “Golden” grown in the Republic of Kazakhstan. The amino acid composition of flaxseed cake was compared with other cakes used in feeding farm animals and poultry. The purpose of the study is to study the fractional composition of the protein complex of flaxseed cake from flax variety "Kostanay 11". A characteristic feature of the protein complex of flax seeds is the high total content of water- and salt-soluble proteins - albumins 29,2% and globulins 16,8%, which are considered well digestible. Flaxseed cake from flax variety "Kostanay 11" in its amino acid value is equal to the known cakes common in feed production and is second only to soybean cake. This allows us to assert that flaxseed cake obtained from the seeds of the “Kostanay 11” variety remained a highly digestible and highly nutritious product in terms of protein absorption, suitable for its inclusion in the diets of all types of farm animals and poultry, starting with feed for young animals.

Food safety has been a concern for consumers, especially when storing various types of meat. Non-thermal technology, in particular electron beam irradiation, can ensure the safety of poultry meat by inactivating food pathogens without significantly affecting its nutritional and organoleptic characteristics. Compared to other non thermal methods, electron beam irradiation is considered a new non-thermal technology for meat due to its low cost, lack of contamination, and antibacterial effect. However, this technology still has some limitations, such as lipid oxidation (LPOD), protein oxidation (PNOD), physicochemical changes, and organoleptic changes, which limit its application in various types of meat. The aim of this scientific study is to highlight new ideas for the application of electron beam irradiation in poultry meat storage. This article focuses on the application and mechanism of electron beam irradiation sterilisation, justifies the electron beam irradiation dose, and highlights areas for future research. In addition, particular attention is paid to optimising processing parameters to minimise quality deterioration while maintaining microbiological safety and extending shelf life.
