Among many environmental conditions that affect a person, the most important factor is nutrition. Today, there is no doubt that there is a direct link between nutrition, health and disease. Proper nutrition ensures normal growth and development of a person, contributes to the prevention of diseases, has a positive impact on life expectancy and creates conditions for adaptation to the environment. A very actual topic for public catering in the Republic of Kazakhstan, namely for fast food companies, is the development of new recipes and culinary products from relatively inexpensive vegetable raw materials, as well as qualitatively new food products with a purposefully changed chemical composition. One of the main ways of solving problems of expanding the production of products for quick service, as well as products for dietary and therapeutic and preventive nutrition is the use of sprouted grains and beans. In this article, poly-grain mixtures of sprouted wheat and extruded soy beans in different ratios are studied and considered. Poly-grain mixtures developed by us are balanced in nutrients, vitamins and amino acids. The research was carried out on the basis of the accredited testing laboratory of RUBICOM enterprise LLP and the scientific laboratory of the Innovative Eurasian University. The purpose of this work is to study a promising method for increasing the nutritional value of grain mixtures by extruding them at different temperature conditions. To achieve this goal, the following tasks were planned: – to study the grain of soy beans and sprouted wheat on the organolepti c characteristics and chemical composition of the poly-grain mixture; – examine the chemical composition of the poly-grain mixture before extrusion; – choose the optimal mode of the extrusion process; – study and analyze the chemical composition of poly-grain extruded mixture; It should be noted that we have developed for the first time the optimal technological mode of extrusion of poly-grain mixture from sprouted wheat and soy beans, and the physical and chemical composition of the poly-grain mixture was studied. The results of the research presented in this paper are the basis for the development of recipes and technologies for fast food products. The reliability and validity of scientific statements is confirmed by the choice of modern methods of chemical composition analysis.

The article is devoted to the current problem of differential diagnosis of diseases of viral etiology in farm animals. Viral diseases are currently widespread, occupy a leading role in the infectious pathology of farm animals, causing enormous economic damage. Given the magnitude of animal vaccine prophylaxis, in order to increase the effectiveness of antiepizootic measures, the urgent issue i s the development of methods for the rapid and effective detection and differentiation of field and vaccine strains of the infectious rhinotracheitis virus in cattle. The possibility of using a polymerase chain reaction to identify and differentiate a vacc ine strain from epizootic strains and isolators of the cattle infectious rhinotracheitis virus is considered. In the process of research, a PCR-RFLP analysis method was developed to detect the IRT virus in the test material. The PCRRFLP analysis method was used to identify and differentiate the vaccine strain TK-A form epizootic strains and isolators of the cattle IRT virus. The principle of PCR, based on repeated repetition of DNA cycles, annealing and synthesis, which leads to an increase in the number of specific DNA fragments of the pathogen, allows you to take into account the results of PCR in an agarose gel. Analysis time is about 30 hours. The sensitivity of detecting viral DNA is 1-10 picograms (102 TCD). Due to characteristics such as relative simplicity and reaction rate, high sensitivity, specificity and reproducibility, PCR has recently become widespread in basic and applied research in various fields of biological science, including veterinary virology. The results obtained during the studies show that the use of PCR-RFLP allows to differentiate field and vaccine strains and isolates of the IRT virus with a high degree of reliability. The use of PCR -RFLP analysis increases the efficiency and informativeness of studies in the molecular epizootol ogy of cattle RTI, as it allows not only to identify the DNA of different virus strains regardless of their nature, but also to differentiate between them, including differentiating the strain TK-A used for the production of attenuated vaccines against epizootic strains and isolates of the virus.

The article discusses various aspects of project management, which is one of the most effective tools and allows you to skillfully take into account various factors, as a result of which the reliability of implementing successful changes and achieving goals in all types of professional activities increases. In Kazakhstan, project management dates back to the 1990s, but the real practical application of this management tool is observed at the beginning of this century. According to the authors, one of the key problems of widespread implementation and use of the project approach in the private and public sectors is the lack of information and methodological support for the development of this area. The purpose of this study is to systematize the theoretical and methodological aspects of project management in the context of improving the quality and efficiency of economic decisions. Any project is a change that is caused by the creation of innovations and the corresponding investment and other resources, on the one hand, and on the other hand, is implemented in conditions of high uncertainty and risks. The research uses the following methods: comparative analysis, a systematic approach based on which General and specific features of project management are identified, as well as abstract-logical. In the context of globalization, modern management principles require a team approach to solve problems aimed at achieving the strategic goals of companies, organizations and States, as well as ensuring continuous improvement of business processes, implementing any changes of a socio-economic, organizational or other nature. The processes that ensure an effective transition to project technologies, as well as important components of the project approach from the point of view of achieving project goals are identified. It is shown that project management is especially widely used in private companies. Currently, this tool is being actively implemented in the management system of state structures in different countries. The significance of the research results lies in the fact that knowledge about the project approach is generally recognized scientific direction, which is characterized as an independent sphere of professional activity and a system of lean management aimed at improving the economic efficiency of implemented projects. In General, despite the noticeable activation of project management promotion processes in Kazakhstan, it should be noted that an important task is to transfer modern technologies of the project approach as a tool for innovative development to all spheres of life of the Kazakh society.

The article is devoted to the mathematical modulation of a complex of experimental data obtained in the process of experimental studies of processed cheese products, processed by mathematical methods. The purpose of this study is to establish the type and amount of the melting salt that promotes the formation of the plastic structure of the processed cheese product. The analysis of scientific research in the field of food technologies showed that mathematical modeling is used in the following areas: clarification of the modes of technological processes, design of recipes and assessment of the quality of finished products, as well as forecasting the shelf life of new products when they are put into production. The most relevant in describing the processes of food production are models of multivariate variance-regression analysis using methods of mathematical planning of the experiment. The authors carried out mathematical modeling and established graphical dependencies characterizing the degree of influence of the regulated factors X1 and X2 on the controlled ones that determine the quality and safety of processed cheese products. It is important that the mathematical analysis of the graphical dependences of the rheological parameters on the adjustable factors indicates the reliability of the data obtained. It is concluded that an increase in the melting salt dose leads to an increase in the – limit shear stress, which reflects the nature and state of the consistency of the processed cheese product. The process of normalization of the controlled factors by the maximum value was carried out. Graphical dependencies were built and regression analysis was performed, the results of which allow an objective assessment of the degree of influence of the type and dose of the melting salt on the chemical and organoleptic characteristics of the test products. The authors have proven that the optimal efficiency of transforming the structure of the constituent components of the recipe into a plastic structure of a processed cheese product that is stable during storage is provided by a combination of adjustable factors X1 (Solva 85) and X2 (Solva 120) taken in a ratio of 1: 1, with a total amount of 1,2 mas.%. At the same time, the quality indicators of the experimental products are characterized by the following values of the controlled factors: У1 – 1280 Pa; У2 – 9 points, У3 – 9,301 (2,0-2,2109 colony forming units /g).

Main problem: The article highlights the problem of tests as methods of psychology, the influence of validity and reliability on the results of psychological research. Purpose: Uncovering the significance of validity and reliability on psychological research results. Results and their significance: Testing is an important method in psychology, allowing measuring various aspects of the psyche and behavior of a person. The history of the development of tests in psychology goes back more than a century and began with the work of Francis Galton and Alfred Binet. Over time, the tests have become widely used in various fields such as education, personnel selection, clinical diagnosis and research. Basic requirements for tests include reliability (repeatability of results), validity (measurement accuracy), standardization (same test conditions) and objectivity (lack of subjectivity in assessment). Tests must be designed using psychometric principles to ensure accuracy and validity of results. Modern tests include a variety of measurement techniques, such as tests of personality, intelligence, aptitude, and professional skills. The use of tests in psychology requires professional training to correctly interpret the results and make valid conclusions. Testing as a method of psychology continues to evolve, and its role remains key in the study of the human psyche and behavior. Testing in psychology has a wide range of applications, including assessing personality traits, identifying psychological disorders, and predicting behavior and success in various areas of life. The development of computer-based tests and online platforms makes testing more efficient and convenient for researchers and participants. Modern tests increasingly take into account cultural differences and the diversity of individual characteristics, which contributes to more accurate and tailored assessments. It is important to remember that the use of tests requires ethics, confidentiality and compliance to ensure the reliability and validity of the data obtained.
