The study focuses on controlling the color formation and color stability of cooked sausages by deliberately varying two functional ingredients: collagen hydrolysate from low-value by-products and cranberry powder. The aim was to quantitatively describe the dose-response effects of these factors on the integral color stability and to propose a technologically feasible optimal range. The methodology included the preparation of five experimental samples (control; 10% hydrolysate; and 10% hydrolysate with 1, 2, and 3% cranberry), instrumental color evaluation in the CIE Lab* system before and after 60 minutes of exposure and calculation of the percentage of stability based on normalized changes in L*, a*, b*. Based on these experimental points, a full-square regression model RSM was evaluated, after which theoretical values were calculated on a regular grid of factors (hydrolysate 0–15%, cranberry powder 0–3%) for surface visualization and optimization. The experimental data showed that the best color stability indicator was demonstrated by the sample with 10% hydrolysate and 3% cranberry powder – 90,24%. Approximation by the RSM (R²=0,995; R²_adj=0,991) revealed a dominant positive linear contribution of cranberry powder, a stable negative linear contribution of hydrolysate, and negative quadraticity for cranberries (saturation of the effect); the interaction of factors is statistically insignificant. Practical significance – recommendation to minimize the proportion of hydrolysate to about 5-10% and dose cranberries at 2-3% to achieve a stability plateau with low sensitivity to dosing errors.

Iron deficiency and milk fortification
Статья научная
Modern food products do not contain a high content of nutrients, in particular minerals. The consumption of such products affects not only the health of the nation but also the economy of the country. According to the World Health Organization, the lack of the mineral element iron remains relevant, especially among children and pregnant women not only in developed countries, but all over the world. This article presents studies of the effect of cow's milk enrichment on the physico-chemical and organoleptic qualities of fortified milk. The cow's milk with a fat content of 3.6 and 2.8% was enriched with iron sulfate (FeSO4.7H2O) and trivalent ammonium citrate (C6H8FeNO7). The samples of Ferrous Sulfate (10mg) and Ferric Ammonium Citrate (10mg) showed significant changes in milk with fat content 2.8 % fortification. The effect of iron enrichment on the process of milk fermentation was also studied, and a milk sample was taken. The milk sample fortified with iron had a considerable acidity increase on 3 h from 22°T to 800T, this is by 37 % compared to the control sample. The effect of iron enrichment on the fermentation process or the supporting role of iron in the growth of fermenting bacteria is still in question, although a number of studies have been conducted in this area, but more clarity and specific research and experiments on this issue are still needed.

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.
