In recent years, the prospect of improving the technology of cereal cottage cheese using linseed oil has been widely used to improve and maintain their quality, increase the biological and nutritional value of the finished product, and increase the shelf life. In the course of the work, the number of components of the cottage cheese with the addition of linseed oil was selected, a technological scheme was developed. Physicochemical and microbiological changes were investigated, and the energy value of the resulting product was calculated. (per 100 g of product: 774kj/178 kcal: fats 10.42 g (52%); protein 18 g (40%); carbohydrates 3.3 g (8%)).

The article presents the results of developing recipes for domestic extruded starter compound feeds for zander, tilapia and Clary catfish. Technological modes of their production, as well as physical-chemical, mechanical and technological indicators of the developed compound feeds are established. The developed compound feeds are well-loose grains of dark and light brown colors, with sizes from 0,2 to 2,0 mm. Indicators of water resistance were at least 2,5 hours, crumbling no more than 1,5 %, swelling of granules 10-15 minutes, volume mass below 1000 kg/m3. The data obtained show that the developed feed meets the regulatory requirements for starting fish feeds. The introduction of the developed technology for the production of starter compound feeds at domestic enterprises of the feed industry will reduce the dependence of industrial fish farms on the import of compound feeds and thereby increase the profitability of the industry.

There are not so many fermented milk products recommended for use in gerodiet. Among them, for the first time, the textural characteristics of curd mass made from camel milk with the addition of flaxseed flour were investigated. As a result of the study, it was found that camel milk curd differs in hardness, adhesion and distribution compared to cow milk curd. In terms of adhesion, the camel milk curd was 44.52% higher than the cow milk curd and 85% lower than the cow and camel milk curd. The adhesion of the curd mass from cow's milk was the least important among the curd mass. It was noted that the time taken to dispense the camel curd was 50% less than the time taken to dispense the cow's milk curd. However, all samples of curd mass did not differ significantly in hardness. As a result of the study, it can be concluded that camel milk curd mass in terms of chewing, distribution and firmness can have an effective texture profile compared to other samples.

Modern trends in the development of pasta production are based on the use of starch-containing raw materials for the production of medicinal and preventive pasta products. In this connection, an important observation is the state of protein and starch in pasta flour, which can be achieved by electron microscopy of the microstructure of macaroni products. Therefore, the study of microstructures and microbiological indicators of pasta from non-traditional raw materials will be relevant. The practical value of the research is characterized by improved consumer properties of pasta made from non-traditional raw materials. The novelty of the research is the development of scientific and technological bases for the production of pasta from non-traditional polycereal raw materials. The results obtained: the analysis of the obtained electronic micro-drawings showed that the microstructure of pasta from non-traditional raw materials corresponds to the standards in comparison with the control sample. The following types of mycotoxins were found in pasta from non-traditional raw materials in permitted quantities: aflatoxin B1, aflatoxin M1, zearalenone, deoxynivalenol, ochratoxin A, fumonisin, patulin, T-2. For example, the amount of zearalenone (mg/kg): in pasta according to recipe No. 1 – 0.0637, according to recipe No. 2 – 0.0251 and according to recipe No. 3 – 0.0758; in flour raw materials – according to recipe No. 1 – 0.1485, according to recipe No. 2 – 0.0261 and according to recipe No. 3 – 0.2.

Temperature fluctuations cause significant harm to the quality of poultry meat and its food safety, both at various stages of storage and transportation, as well as sales. Repeated repeated defrosting and freezing lead to a violation of the integrity of cells or protein denaturation, which is accompanied by a change in the ratio of the forms of moisture binding to the product. In this regard, there is an urgent task of establishing the facts of thawing and freezing of poultry meat, determining the number of cycles of repeated freezing. This article is devoted to the development of a new express method for determining the number of cycles of freezing – thawing of a broiler at the stages of the life cycle of poultry products. As the number of «freeze-defrost» cycles increases, the peak area of the differential scanning calorimetry curve (DSC) decreases from 206.4 to 192.6 kJ/mol with electric stunning and from 168.6 to 151.5 kJ/mol with gas stunning, the melting peak temperature also decreases from 5.7 to 5.2 oC with electric stunning and from 5.0 to 4.0 oC with gas stunning. The DSC temperature program and recommendations for its use for monitoring broiler processing and storage processes accompanied by phase transformations of water have been developed.

In recent years, the production and consumption of poultry meat has been widely used both on the world market and on the market of Kazakhstan, one of the reasons for which is that poultry products are more accessible to consumers than animal products. With such an import structure, it can be assumed that the volume of imports of cheap chicken from abroad is a function of the income level of the population: the smaller the proportion of the population with a certain low income level, the less imports. For the effective development of poultry farming in Kazakhstan, it is necessary to overcome a number of constraining factors, one of which is the insufficient modern safety control system throughout the poultry meat production chain. The article develops a flowchart of the semifinished product production process based on poultry meat-broiler with soy flour, examines possible risks (hazards) for the development of management measures in the production of semi-finished products, identifies three control critical points for the production of semi-finished products from broiler meat with soy flour.

This article provides insights into qualification testing, interlaboratory comparative testing, and qualification testing programs in testing laboratories that analyze the safety of meat and meat products. Samples with codes OK-MB- 21 were used as a model for interlaboratory comparisons. The uniformity and stability of the CC code was assessed in accordance with GOST R 50779.60-2017 “Statistical methods. Application in proficiency testing through interlaboratory testing ”. Seven laboratories participated in the proficiency testing program. The test preparation procedure was described and the test results determined whether each sample tested was satisfactory or questionable. Participants with unsatisfactory results are encouraged to identify the causes of the alarms, take corrective actions and document them, and identify and eliminate the causes of the unsatisfactory results.

This article discusses the determination of the optimal design allowances for a full factorial experiment in the development of special-purpose clothing for patients with thermal injuries in a hospital. To assess the ergonomic performance of special-purpose clothing, was used of pressure exerted by clothing on the human body. Based on the results of the study, a mathematical model was developed based on a full factorial experiment. In accordance with the presented mathematical models, the minimum values of contact pressures are obtained for the following values of construction parameters: for a cut with a sewn-in sleeve Warmhole = 15 cm, Ifa = 5,0 cm, Ic = 9 cm, Hse = 10 cm; for a cut with a raglan sleeve Warmhole = 15 cm, Ifa = 6 cm, Ic = 10 cm; for a cut with a one-piece sleeve Warmhole = 16 cm, Ifa = 6 cm, Ic = 11 cm.
