Among the different types of the population, primary school students are a particularly important stratum. Because in secondary educational schools children are fed 3-4 times. When a child grows up and enters primary school, he is not fed in schools, because today there is no way to provide him with proper nutrition. As a result, there is a lack of vitamins, micro- and macronutrients necessary for the development of the child's body, and the energy sources used during schooling cannot be adequately covered. Such situations have a negative impact on the health of our children, who are the future of our country. Many diseases occur in children due to anemia, avitominosis, deficiency of calcium, phosphorus, iodine. 

The article presents data on the study of the chemical composition of seeds of local varieties of millet and considers the possibility of its use in the production of concentrated dry mixes. Millet is one of the oldest grain crops cultivated in many regions of Uzbekistan. Millet groats and flour are produced from millet. Millet occupies one of the first places in terms of taste and nutritional value. Millet is considered one of the most nutritious and least allergenic grains. Millet is a source of some vitamins (especially the B group), starch, amino acids, minerals and fiber. Millet is easily absorbed by the body and has a general strengthening effect on it. The analysis of the presented data confirms that millet is a product of high nutritional value and is recommended for use in the production of concentrated dry mixes.

The effect of various reagents on the quality parameters of cottonseed oil was investigated and the optimal reagents were selected. In the alkaline refining of cottonseed oil, the use of an aqueous solution of sodium silicate instead of a portion of the traditional caustic soda has been found to improve the quality of the oil. The technology of step-by-step refining of cottonseed oil with aqueous solutions of traditional caustic soda and sodium silicate has been developed.

Alkaloids differ in their physiological effects: some of them weaken or stimulate the nervous system, others paralyze nerve endings, dilate or narrow blood vessels, and others are considered to have an analgesic effect. It is studied using methods such as chromatography, spectroscopy, and continues to get high results in these methods. The advantage of this method is that in the study of alkaloids, the additives contained in alkaloids are considered extremely necessary for the study of organic and meningeal substances, as well as for the analysis of biological objects. The chromatography method is widely used in the study of detection, isolation of compounds contained in alkaloids. On the other hand, the spectroscopy method is studied by exposing light to alkaloids. The chemical composition of alkaloids is studied by ultraviolet light and some reagents.

Today, reducing the amount of trans acids in fats is one of the urgent issues, and several methods of its elimination have been developed. In this study, the technology of hydrogenation of vegetable oils in the state of supercritical fluid was studied through literature analysis. The principle scheme of the technology of hydrogenation of vegetable oils in the state of supercritical fluid has been developed and the norms of the technological regime have been determined.

Coconut oil should be used in chocolate and chocolate products. However, due to the high cost of coconut oil, its substitutes have been developed. The article contains information about cocoa used in chocolate products and oils used instead. Also, the results obtained as a result of the analysis of the physical-chemical parameters of confectionery oils and coconut oil substitutes used in chocolate products are presented. As a result of the research, it was found that the amount of trans fatty acids in the analyzed oils is higher than the standard norms.

Today, in our Republic, most of the baking oils are margarines prepared on the basis of food salami. These margarines do not meet the standards of trans acid content (more than 2%). The research paper presents the results of hydrogenation of cotton palmitin in the presence of a regenerated catalyst, the melting temperature of which is less than 59 °C and the iodine number of no more than 6, and the preparation of a recipe for margarine with reduced trans acid content, which is used in baking based on it.

Since margarine is a substitute for butter, milk is added in most margarine recipes. However, the cost of margarine obtained for the cost of cow's milk exceeds. The article presents the results of experiments on obtaining milk from soy beans and its use in place of cow's milk in margarine. When soy beans were taken and analyzed using soy milk in an traditional way, it was found that its ingredients were close to those of cow's milk. In particular, the protein content is 3.48% in soy milk and 2.31-2.84% in cow's milk. The carbohydrate content is 2.10% and 8.48 8.91%, the fat content is 1.96% and 0.11-0.14%, and the ash content is 0.28% and 0.21-0.26%, respectively. Cow's milk made a serious difference from soy milk in the amount of carbohydrates. On the basis of the resulting soy milk, a margarine recipe was formed and margarine was prepared. All the margarines obtained complied with the requirements of O’zDSt 3317-2018 in terms of quality indicators. It was observed that the consistency (plasticity, solubility, surface area on the cut) of margarines obtained only on the basis of the recipe with the addition of soy milk is relatively good.

Today, the requirements for proper nutrition and a healthy lifestyle are increasing every day. However, the population of our country has long been consuming a large amount of fat (including margarine) products, and the fulfillment of the above requirements creates certain problems. One effective solution to these problems is to change the composition of the daily consumed products and bring them to the level of requirements. The purpose of the research is to increase the biological value of the resulting product by enriching the fat base of margarine with polyunsaturated fatty acids. For this, it is proposed to completely abandon the traditional hydrogenated fat, and an interesterified mixture based on beef fat, cotton palmitin and soybean oil is proposed.

The emulsifier is the main raw material for the production of emulsion products, including margarine. To date, soy lecithin E322 is imported to our republic from abroad and is widely used in the margarine industry. The aim of the study is to use soy lecithin extracted from local soybean oil in the production of margarine products and compare it with E322. As a result, the efficiency of lecithin extracted from local soybean oil for margarines with a high solid fat content was higher than E322.

Today, extraction gasoline is used in the production of vegetable oils. For several years, this solvent was not enriched with any additives to improve the efficiency of vegetable oil production, or another type of solvent was not used instead. For this reason, in our research work, instead of extraction gasoline, we proposed its analogue. Based on the results obtained, it was determined that the proposed analogue allows to speed up the process and improve the quality of the extracted oil compared to traditional extraction gasolines.

It is known that for average physical activity, a person is recommended to consume food
products equal to 1200-1300 kJ of calories per night. 100 g of bread contains 1100-1300 kJ. The amount of food required for proper nutrition depends on people's age, gender, work activity and climatic conditions. In terms of nutritional value, flour and flour products rank high.
Year by year, the population's demand for high-quality flour products is increasing, and as a result, manufacturers are taking measures to further improve the quality of products. As a result, manufacturers require monitoring of product analysis with modern equipment and facilities. In addition, manufacturers
are constantly researching not only their own flour products, but also the products of enterprises that produce similar products.

The work presents the results of the research of an integrated circuit in order to read the influence of differential blocks on the drying process. The experiments were carried out selectively on a new integrated circuit due to heating of an air flow with pulsating oscillations.

Since glycerin is obtained from vegetable oils and fats, its quality directly depends on the quality of oil and fat. Also, the methods and technologies of obtaining and processing glycerine affect
the quality of glycerine. Based on the results of IK analysis, it was shown that the use of a mixture of
adsorbents to improve the quality of distilled glycerin is effective in the research work. If we look at the IR analysis results of purified glycerol, the IR spectrum of glycerol showed O-H stretching at 3338.15 cm -1 , and C-H stretching was detected in the peaks in the region of 2800-2950 cm -1 . The C=O stretching band present in unbleached glycerol at 1736.58 cm -1 is not present in the spectra of eluted glycerol. It was observed that the peaks observed in the spectra above 3600 cm -1 also disappeared. This means that the phenolic group of substances in refined glycerin has been purified.

At the same time, the issue of ensuring the quality of wheat, its technological properties, is of social and economic significance, since bread and bakery products occupy a special place in the nutrition of the population of the Republic, as traditional, irreplaceable products of everyday demand, available to all segments of society. Along with the increase in wheat production, improving its quality, a certain part of the wheat is used for fodder, technical and other purposes due to the insufficient quantity and low quality of gluten. One of the reasons for the decline in the quality of
the gluten of food wheat is the damage to crops by the pest "turtle bug".
