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.

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.

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.

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.

The use of combined structuring agents of various origins in the production of jelly products
Статья научная
This paper is devoted to solving an important task of the food industry - the rational use of food raw materials, including gelling agents of various origins. The innovative strategy of this study is based on the possibility of using gelatin and modified potato or pea starch (MS), as a cheap ingredient in the production of jelly products based on traditional, but expensive raw materials such as agar and agar from Furcellaria - furcellaran. The experimental study has been performed concerning the strength of gel-forming systems ‘gelatin - MS - agar - water’ and ‘gelatin - MS - furcellaran - water’, and systems: ‘agar - water’, ‘furcellaran - water’, ‘gelatin - water’. Mathematical models have been obtained that relate the strength of the investigated gel-forming systems to the mass concentration of their components. The equation has been obtained that allows calculating the mass concentration of the components of the studied gel-forming compositions with the given level of strength of systems. It is shown that for a given level of strength of gel-forming system there is an optimal concentration of its components in terms of the least full cost of the system. The equation that allows to calculate the optimal concentration of components of a combined gelforming system has been obtained. The adequate mathematical model for forecasting the strength of jelly products, depending on the mass concentration of components is obtained. It is envisaged to formulate the initial requirements for the parameters of gel-forming, which will allow obtaining an integral elastic structure at optimum duration of the technological process, by modelling the systems of gel-forming, as a technological system, within the framework of the functioning of individual subsystems (the creation of prescription concentrations and ratios of gel-forming agents). The obtained mathematical models can be used for the analysis of other gel-forming compositions in the presence of the data on the strength of such systems depending on the concentration of components.

Статья научная
The demand for natural and functional food products is constantly increasing, driving the research on new ingredients and technologies to enhance the quality and safety of meat products. This literature review focuses on the application of new functional ingredients and traceability of meat products to ensure their quality. The study examines the surface treatment of meat with bioactive substances such as dihydroquercetin from Larix sibirica Ledeb, rosemary extract (Rosmarinus officinalis), and distilled rose petal extract (Rosa damescena Mill.). Additionally, the inclusion of functional ingredients such as dried goji berries (Lycium barbarum) and pumpkin (Cucurbita moschata) in meat matrices is discussed. The research highlights the potential benefits of these functional ingredients in inhibiting lipid oxidation, preserving color, and improving the taste qualities of meat products. The inclusion of natural antioxidants and bioactive compounds derived from plants presents a promising alternative to synthetic additives. Furthermore, the reduction of potentially harmful substances, such as nitrites, in meat products is achieved through the inclusion of functional ingredients. To ensure the quality and safety of these functionally processed meat products, a traceability system is proposed. This system includes documentation of ingredient origin, production processes, and packaging information. Implementing a traceability system enables the tracking of product movement and distribution throughout the supply chain, thereby confirming the positive effects of the ingredients and ensuring consumer trust. The aim of this article is to integrate new functional ingredients and implement a traceability system to enhance the quality, safety, and acceptability of meat products by consumers. These approaches align with the growing demand for natural and high-quality food products, opening opportunities for innovation in the meat industry. Funding information: The materials were prepared within the framework of the "Zhas Galym" project within the scientific and technical program AP15473123 "Digitalization of the traceability system of meat products to improve the quality of semi-smoked sausages during long-term storage" of the budget program 217 "Development of Science" subprogram 102 "Grant financing of scientific research" of the Ministry of Science and Higher Education of the Republic of Kazakhstan for 2022-2024.
