The article experimentally substantiates the prospects of obtaining powder from eggplant pulp, and its application in the technology of the national fried bakery product-baursaks. There are two ways to prepare eggplant for processing in order to remove bitterness. With preliminary freezing of raw materials, there is a slight bitterness in the aftertaste, and when soaked in a 3% salt solution, the taste of the powder is salty. The optimal parameters and modes of convective drying of eggplant fruits for the most complete preservation of biologically active substances in the product are established. The scientific novelty is confirmed by the patent of the Russian Federation № 2733117, a method for obtaining powder from the pulp of eggplant. The formulations of the experimental variants differed in the content of eggplant fruit powder by 15, 20, 25%. With an increase in the amount of eggplant pulp flour in the recipe to 20–25%, the color of the semi-finished product darkens, the dough becomes incoherent, breaks, because the content of raw gluten decreases in mixtures. According to the results of a comprehensive assessment of the quality of finished products, the best sample with the addition of eggplant pulp flour up to 15% in the product formulation. The authors found that in 100 g of baursaks with the addition of eggplant powder, the content of dietary fiber is 37,5% higher, vitamin B6 is 3 times, silicon, manganese, copper is 1,5 times. A new recipe of the national bakery product - baursaks has been developed, which contributes to the expansion of the range of products of increased nutritional value

In the course of research, experiments were conducted to study and describe the biological and economic features of Allium oschaninii O. Fedtsch. and Allium pskemense B. Fedtsch. in the Moscow region. The object of the research was samples of various ecological and geographical origin, obtained from various scientific institutions in Russia and other countries. The landing scheme was 70x30 cm. The area of the registered plot was 5 m2. Repeatability 4 times. Samples of Allium oschaninii O. Fedtsch. II years of life provided an average yield of green feathers at a level (2.85-3.86 kg/m2), and Allium pskemense B. Fedtsch. (2.593.20 kg/m2). Maximum yields were provided by samples No. 3 and No. 6 of Allium oschaninii O. Fedtsch. and samples No.3 and No.5 of Allium pskemense B. Fedtsch.. Correlation analysis showed that high productivity of the green feather is formed, first of all, due to the number of false stems (r = 0.909). Significant influence is exerted by such features as the number of leaves (r = 0.633), leaf length (r = 0.630), and the length of the false stem (r = 0.604). The nutritional value of Allium oschaninii O. Fedtsch. and Allium pskemense B. Fedtsch. is due to the presence of ascorbic acid (19.2-32.6 mg%), carotene (14.9-26.1 mg%) and biologically active substances, including flavonoids (251-325 mg% ), hydroxycinnamic acids, (155-194 mg%). The content of dry substances in the samples of the two onions studied was 10.3-12.7%, sugars 2.8-4.2%. The nitrate content did not exceed 170 mg%.

The usage of various sourdoughs increases in order to expand the range and improve the quality, nutritional properties, and safety of bread products. Spontaneous sourdoughs with different formulas and preparation parameters are used in technologies of popular ethnic products. This paper is devoted to the study of wheat spontaneous sourdoughs, such as hop, pea-anise, and wine yeast sourdough. The effect of the grade and baking properties of flour, the inclusion of additional ingredients that can act as enrichers of the nutrient medium, carriers of additional fermentation microorganisms, as well as controllers of the species composition of the microflora, on their quality has been studied. The basic scheme of preparing spontaneous wheat sourdough is developed; the basic stages and parameters of the dilution and production cycles are noted. The methods of controlling the process and quality of sourdough are described, the recommended values of the lifting force and titrated acidity are presented, as well as sensory characteristics. It has been established, that the required fermentation ability and acid accumulation rate of sourdough are obtained in different time: 24 hours for wine yeast sourdough, 7–8 days for hop sourdough, and up to 15 days of a dilution cycle for pea-anise sourdough. The stabilizing effect of active substances of hop and anise on the quality of sourdough has been proven. Hop and pea-anise sourdough retain the necessary biotechnological properties for 90 days of propagation, but wine yeast sourdough loses its quality after 30 days, sourdough without additives loses it after 9 days. The results of the research have theoretical and practical use, since the proposed scheme and approaches to developing the wheat sourdough technology and controlling their quality can be used to study various ethnic sourdoughs and technology of bread based on them. The experimental data on the quality of selected sourdoughs can be used to develop the technology of bread products with improved quality, nutritional value, and safety, ethnic products, and products "made according to old technologies".
