Purpose. Study the effectiveness of a new feed additive based on vegetable cake and lactulose introduced into the diet of young rabbits in order to increase productivity. Materials and Methods. During the research, the objects were rabbits of the Californian breed, which were divided into 2 groups (control and experimental), in each group of 15 heads, according to the principle of analogues, as well as a feed additive based on milk thistle cake and lactulose. Experimental studies on the determination of growth dynamics, determination of slaughter indicators, as well as biochemical and morphological indicators of blood were carried out in a complex analytical laboratory by using standardized research methods. Results. During the experiment, it was found that the introduction of "Lactu-Super" in the amount of 5% by weight of feed contributed to an increase in the concentration of erythrocytes, leukocytes and hemoglobin, which corresponded to a higher level of metabolism, as well as the pre-slaughter weight of animals by 3.7% and slaughter weight, slaughter yield of 141.6 g and 2.0% relative to the control group that did not receive the supplement. Conclusion. The results of scientific and economic experience have demonstrated the effectiveness of using a new feed additive based on vegetable cake and lactulose for fattening hybrid rabbits under intensive technology from the age of 45 days.

Purpose. Evaluation of various types of modern lactulose-containing additives and the effectiveness of their use in feeding farm animals as one of the options for decision the problem of in vivo formation of high-quality and safe livestock products for the healthy nutrition of the modern population. Discussion. The revolution in feed production made by the Soviet scientist Minenkov A.R. in the middle of the 20th century, namely the use of antibiotics as a feed additive to stimulate productivity, became a failure by the beginning of the 21st century. By this time, the negative consequences of prolonged use of antibiotics were revealed, which led to the active rejection of them in animal husbandry practice as productivity stimulants. They were replaced by pro- and prebiotic feed additives that have a healing effect on animal organism, thereby beneficially influencing their productive characteristics. Prebiotics in feed production are more convenient to use than probiotics, as they have a greater degree of unpretentiousness to storage conditions, but at the same time they are easier to obtain than live microorganisms. Lactulose is the most well-known and proven prebiotic in animal husbandry. Feed additives based on it in the body of animals have an identical mechanism of action based on enzymatic cleavage in the large intestine of this disaccharide by bifidobacteria and lactobacilli, which triggers a number of interrelated processes that have a beneficial physiological effect. The considered results of the use of some lactulose-containing feed additives on broiler chickens, Saanen goats, pigs and rabbits made it possible to conclude that for the above animal species there is a similar positive effect from the presence of new lactulose-based feed additives in the diet: intensification of growth and development of animals, as well as strengthening of resistance to adverse external factors, which directly affects the life-time formation of better and safer livestock products. Conclusion. Reviewed studies on the use of modern lactulose-based feed additives and the results obtained confirm their ability to have a beneficial effect on the growth, development and resistance to negative factors from outside the body of farm animals, such as broiler chickens, goats, pigs and rabbits. This, in turn, contributes to the lifetime formation of improved quantitative and qualitative characteristics of the resulting livestock raw materials.

Purpose. Study of the influence of various methods of preparing raw materials for the production of native steaks on quality and organoleptic characteristics. Materials and Methods. The object of research was native beef steaks, which were made from raw materials obtained by various preliminary processing. Depending on the type of technological influences, the organoleptic characteristics of products (GOST 32125-2013), shear stress (GOST 52601-2006) and mechanical strength of meat (GOST 31797-2012) were studied. Results. As a result of the experiment, it was revealed that the experimental products (native steaks) had high organoleptic characteristics, namely: a more pronounced taste, color and aroma, consistency. This was achieved due to increased proteolytic activity of proteins, their faster splitting into amino acids, which affects the taste formation. Also, when using the developed method for preparing raw materials, a higher complex effect on meat proteins of proteolytic enzymes of the gastric tract (pepsin and trypsin) was noted and, as a result, an increase in the digestibility of the studied steaks. The methods and modes of preliminary exposure and processing of raw materials contribute to the increase of the hydrothermal effect, which improves their consistency, namely: the steaks processed by the proposed method had better organoleptic properties and more worthy results in terms of the tension of the slice of boiled meat – 350 H/m2, mechanical strength – 52.70%. All this can favorably affect the further development of finished products. Conclusion. It has been established that the use of the developed method of processing raw materials for the preparation of native steaks has a positive effect on the organoleptic characteristics of products, and also improves their quality indicators, which makes it possible to obtain products with good organoleptic characteristics, as well as quality characteristics.

Purpose. Development of a scientifically based concept for the formation of an adaptive approach to the meat and dairy socially significant production based on deep processing of regional livestock raw materials, innovative ways to increase the shelf life of products, reduce the cost of technologies, increase consumer properties of products, incl. specialized and functional, are presented. Materials and Methods. The work is based on the convergence of experiments in vitro, in vivo, in silico. All studies were carried out on advanced equipment using modern methods of chromatography, mass spectrometry, voltammetry, physicochemical and biotechnological methods. Discussion. Minor components of animal raw materials can be effective in the treatment and prevention of lot diseases. Peptides with low molecular weight obtained from bovine lactoferrin have a more significant effect on gastric mucosa protection than native bovine lactoferrin in the same concentration. Using of angiogenin isolated from dairy raw materials, or serum concentrates enriched with angiogenin have a great social and practical importance. A complex of proteinoids obtained from collagen-containing raw materials, including animal skin processing waste, as a result of deep processing, can be widely used in the compounds of various food products: jellies, sausages, chopped meat semi-finished products, etc. Improving the safety of meat quality indicators when stored in a chilled state is possible using the case of its preliminary treatment of following antiseptic solutions: magnetized and electroactivated solution – catholyte; concentrate of mineral salts obtained after electrodialysis of whey. Meat treated with these solutions is more juicy compared with control. Its emulsifying ability is more high (on average 10%), which is important in sausage production. It make possible to exclude the using of third-party chemical reagents, and to increase the physical and chemical indices of meat quality and prevent its microbial contamination. In order to produce food products with the specified quality characteristics, it is proposed to use non-traditional vegetable raw materials with regional and price availability as part of the compositions. As a result of the performed research, enriched meat and dairy products of a new generation with established physiological effects were created. The developed formulations aimed to enrich food with natural bioactive complexes of macro- and micronutrients obtained from regional plant raw materials, secondary raw materials from food manufacturers, as well as to improve the organoleptics of the finished product, reduce its allergenicity, extend shelf life, reduce the cost of technologies, increasing the availability of socially significant products, including special-purpose products, for all segments of the population, consumer attractiveness due to functional properties (various types of yoghurts, cheese and cheese products, boiled and smoked sausages, jel

Purpose. Evaluation of the antioxidant activity of peptides isolated from trypsin hydrolysate of cow colostrum. Materials and Methods. Based on the data obtained, it is possible to consider the possibility of using this peptide in the development of functional food products. However, it should be borne in mind that biologically active peptides have a number of disadvantages, in particular, low stability in the gastrointestinal tract, and can react with other biologically active substances in the composition of a food product and in the human body. Results. The antioxidant activity of peptides was determined by the DPPH method. Solutions of Trolox (6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid) of known concentration were used as the standard solution. All spectrophotometric measurements were carried out using a CLARIOstar micro-tablet reader (BMG Labtech, Germany).Studies of the antioxidant activity of peptides with a known molecular weight and sequence of amino acids isolated from enzymatic hydrolysate of cow colostrum have been carried out. The functions of these peptides are not presented in the scientific and technical domestic and foreign literature. The antioxidant activity was determined by the DPPH method. It was found that the peptide with the amino acid sequence SQKKKNCPNGTRIRVPGPGP, consisting of 20 amino acids and having a molecular weight of 20 kDa, has an antioxidant activity of 0.128±0.008 mmol eq. Trolox/l, the antioxidant properties of the other peptides studied have not been established. It can be assumed that the antioxidant activity of peptides depends on the sequence and number of amino acids. Conclusion. Based on the data obtained, it is possible to consider the possibility of using this peptide in the development of functional food products. However, it should be borne in mind that biologically active peptides have a number of disadvantages, in particular, low stability in the gastrointestinal tract, and can react with other biologically active substances in the composition of a food product and in the human body.

Substantiation of the possibility of using natural melanin in the food industry based on the study of its sources and properties. Discussion. Sources of melanin of plant, animal and microbial origin are systematized, some of which are unsuitable for industrial use – squid ink, sepia, watermelon seeds, etc., and birch fungus chaga as a source of melanin has a long renewal. The properties of melanin – protection from light, chelation of metal ions, antibacterial and antioxidant activity, etc., determine their use in food technology and their primary packaging. Conclusion. Sources of melanin are diverse, but plant raw materials and waste products of its production, in particular, buckwheat husk, are industrially significant. Despite the significant volume of husk – more than 65 thousand tons per year, its use today is extremely limited. Functional properties, low cost and accessibility.

Purpose. Studying the possibility of enriching poultry chopped cutlets with calcium by using the food additive E 333(iii) calcium citrate. Materials and Methods. The object of research was chicken chopped semi-finished products (cutlets) produced according to TU 9214-009-42855891-2002 (GOST 31936-2012). The calcium-containing dietary supplement calcium citrate (GOST R 54538-2011) was used as a mineral concentrator. To determine the optimal amount of calcium citrate application, recipes for chopped chicken cutlets were developed without the use and with the use of calcium citrate in an amount of 1.0 (experienced no. 1) and 1.5% (experienced no. 2) by weight of raw materials. Classical and modern methods of analysis were used in the research: the moisture content in the finished product was determined according to GOST 33319-2015; the amount of protein substances – according to GOST 25011-2017; fat – according to GOST 23042-2015; ash content – according to GOST 31727-2012; the content of carbohydrates in terms of glucose – according to GOST 31470-2012; calcium content – according to GOST R 55573-2013. Results. Experimentally, it was found that the enrichment of the prototypes with calcium citrate had a positive effect on the calcium content in the finished product. Thus, the enrichment of minced meat by 1.0% contributed to an increase in the calcium content by 40.60%, compared with the control sample, and the enrichment of minced meat by 1.5% – by 50.03%, respectively. During the conducted studies, it was found that the content of essential amino acids in the experimental samples was slightly higher than in the control: lysine – by 1.79 and 4.71%, phenylalanine – by 1.87 and 1.07%, histidine – by 0.81 and 0.27%, leucine and isoleucine – by 1.19 and 0.32%, methionine – by 1.80 and 0.90%, valine – by 0.36 and 0.90%, threonine – by 2.96 and 0.85%, tryptophan – by 0.91 and 1.82%, respectively. The caloric content of the resulting cutlets ranged from 209.75 to 209.91 kcal. Conclusion. It has been established that the use of calcium citrate makes it possible to significantly enrich the finished food with this important macronutrient in human metabolism, and the resulting cutlets do not differ in their taste qualities from ordinary chopped cutlets. And the low calorie content of cooked cutlets is ideal for dietary nutrition and people leading a healthy lifestyle.
