In poultry farming, feed remains the most expensive part and farmers are constantly trying to optimize diets, both in terms of price and nutrition, so that the poultry can realize its genetic potential. Such feeding diets should maintain the highest productivity of poultry in a normal state of health; contribute to improving the quality of products and reducing the cost of its production. The purpose of the work was the theoretical and experimental justification of the use of new varieties of sorghum, chickpeas, mustard seed processing products, as well as targeted formulations of biologically active additives (premixes, PVMC, NutoVit additive) based on local feed sources, increasing the nutritional value of compound feed, reducing their cost, increasing egg productivity and obtaining complete food and incubation chicken eggs. The nutritional value of a new variety of chickpeas Privo 1, sorghum Kamyshinskoe 75 with different levels of their input into compound feed instead of sunflower presscake and corn grain for young birds and laying hens, respectively, has been studied in the paper. The effectiveness of using different levels of mustard seed processing products – feed concentrate from vegetable raw materials Sarepta and mustard protein-containing feed concentrate Gorlinka in feeding of laying hens instead of the traditionally used sunflower seed presscake and meal. The influence of the premix and the protein-vitamin concentrate Gorlinka based on the products of processing mustard seeds and the additive NutoVit in the composition of compound feed for chickens of the parent and industrial herd has been determined. The use of non-traditional feed and biologically active additives in the diets of young birds and laying hens has a positive effect on the growth and development of young animals, egg productivity of laying hens and egg quality, as well as increases the efficiency of production.

Представлена информация по изучению технологических особенностей культивирования нового для российского продовольственного грибного рынка вида дереворазрушающего гриба – шиитаке (Lentinus edodes (Berk.) Sin). Шиитаке – один из наиболее перспективных для промышленного культивирования видов съедобных грибов, обладающих лечебными свойствами, занимает второе место в мировом производстве съедобных грибов. Работа по поиску материалов, используемых в качестве добавок к основному исходному материалу субстрата и способствующих созданию благоприятного водно-воздушного и кислотного режима, повышению питательности приготовленного субстрата, ускорению процесса вегетативного роста мицелия в субстрате, актуальна для грибоводческой практики. Цель исследований – разработать технологический процесс полного цикла культивирования шиитаке и установить его оптимальные параметры в производственных условиях ООО «Апрель». Исследования, испытания и разработку технологии полного цикла выращивания шиитаке проводили в лаборатории грибоводства ВНИИО – филиале ФГБНУ ФНЦО и на базе действующего предприятия по выращиванию дереворазрушающих грибов ООО «Апрель» с 2019 по 2020 год. Технология приготовления субстрата и выращивание плодовых тел шиитаке аналогична технологии производства вешенки. Изучено влияние состава субстрата на урожайность шиитаке в вариантах: 1. Опилки дуба (80%) + опилки березы (10%) + минеральные добавки (10%); 2. Опилки дуба (80%) + опилки березы (5%) + лузга семян подсолнечника, отруби пшеничные (5%) + минеральные добавки (10%). Использован штамм шиитаке 0912. В результате апробации разработанного технологического процесса полного цикла культивирования шиитаке в производственных условиях было установлено, что оптимальная продолжительность периода выращивания шиитаке и получение урожая в камерах выращивания составляет в среднем 53–68 суток. Важнейшая составляющая технологического процесса культивирования шиитаке – приготовление субстрата, подбор исходных материалов и биологически активных добавок, обеспечивающих его высокую питательность (содержание общего азота – 0,8–1,2% и более) и возможность получения урожая более 30–35% от массы субстрата с высокой экономической эффективностью от 290% (рентабельность производства). The article presents information on the study of technological features of cultivation of a new type of wood-destroying mushroom – shiitake (Lentinus edodes(Berk.) Sin), which is new for the Russian food mushroom market. Shiitake – one of the most promising types of edible mushrooms for industrial cultivation, which have medicinal properties, occupies the second place in the world production of edible mushrooms. The work on the search for materials used as additives to the main source material of the substrate and contributing to the creation of a favorable water-air and acid regime, increasing the nutritional value of the prepared substrate, accelerating the process of vegetative growth of mycelium in the substrate is relevant for mushroom growing practice. The purpose of the research – to develop the technological process of the full cycle of shiitake cultivation and to establish its optimal parameters in the production conditions of LLC April. Research, testing and development of the technology of the full cycle of shiitake cultivation were carried out in the laboratory of mushroom growing of ARRIVG – branch of Federal Scientific Centre of Vegetable Growing and on the basis of the existing enterprise for growing wood-destroying mushrooms LLC April from 2019 to 2020. The technology of preparing the substrate and growing shiitake fruit bodies is similar to the technology of producing oyster mushrooms. The influence of the substrate composition on the shiitake yield in the variants was studied: 1. Oak sawdust (80%) + birch sawdust (10%) + mineral additives (10%); 2. Oak sawdust (80%) + birch sawdust (5%) + sunflower seed husk, wheat bran (5%) + mineral additives (10%). The shiitake 0912 strain was used. As a result of testing the developed technological process of the full cycle of shiitake cultivation in production conditions, it was found that the optimal duration of the shiitake growing period and the harvest in the growing chambers is on average 53–68 days. The most important component of the technological process of shiitake cultivation is the preparation of the substrate, the selection of raw materials and biologically active additives that ensure its high nutritional value (total nitrogen content of 0.8–1.2% or more) and the possibility of obtaining a crop of more than 30–35% of the substrate weight with high economic efficiency of 290% (profitability of production).

Introduction. With the development of the food and processing industry, the matter of environmental pollution is becoming more and more acute. Environmental protection is based on the principle of rational use of natural resources and sustainable technology. Vegetable pomace is a secondary raw material; its amount depends on the production technology and equipment. The observed positive trend in the gross harvest of vegetables in open ground can increase the number of vegetable processing enterprises and the capacity of existing enterprises. Eventually, waste will start accumulating at processing sites, and it will have to be used as raw materials. The present paper features the content of biologically active substances in pomace of carrots and beets grown on the territory of the Siberian region and introduces options for their further use in functional foods. Study objects and methods. The research featured carrot pomace of the varieties Losinoostrovskaya, Nantskaya, and Queen of Autumn, as well as beet pomace of varieties Cylinder and Bordeaux. All the samples were harvested in the Kemerovo region in 2019. Determination of physical and chemical parameters was carried out using standard methods. Carotenoids, flavonoids, β-cyanine were studied using spectrometry and photocolorimetric method. Results and discussion. The experiment featured the content of bioactive substances in pomace of carrots and beets obtained during industrial processing. The content of carotenoids in carrots (mg of β-carotene per 100 g of dry weight): for Losinoostrovskaya variety – 23.56 ± 0.23; Nantskaya – 25.32 ± 0.18; Queen of Autumn – 20.78 ± 0.25. Flavonoid content (mg of catechol equivalent per 100 g of dry weight): Losinoostrovskaya – 12.02 ± 0.37; Nantskaya – 13.45 ± 0.56; Queen of Autumn – 11.50 ± 0.48. The content of β-cyanine in beets (mg per 100 g of dry weight): Cylinder – 100.0 ± 8.5; Bordeaux – 35.0 ± 1.8. The nutritional value of carrot and beet pomace with a mass fraction of moisture was 10%. The nutritional value of vegetable pomace is due to the high content of dietary fiber; therefore, the raw materials can be considered for functional food production. The content of biologically active substances in vegetable pomace (flavonoids, carotenoids, β-cyanines) can enhance the functional orientation of this secondary raw material when used in food technologies for the production of food of high nutritional value. Conclusion. The results obtained will make it possible to use the biochemical potential of plant raw materials in many aspects, as well as to obtain new functional food products, thereby expanding the range of healthy foods.

One of the most important problems of the population's nutrition is the high caloric content of flour confectionery products, due to their oversaturation with carbohydrate and fat components. This trend leads to micronutrient deficiencies, and later to metabolic problems and deteriorating health. In recent years, there has been an expansion of the range of waffles, improving technology through the wider introduction of various ingredients of plant origin. Crustilian is a crunchy product or component of a dish that has a crispy texture (waffles, cereal breads) or a surface (a crust of bread or potato balls with a fried crust). Crustilian is also used as a layer for cakes or desserts, which usually consists of waffle crumbs, chopped nuts and melted dark chocolate. There are still many variations for making crustilians. The range of applications of crustilian in the manufacture of sweet dishes is extremely wide. The nutritional value of crustilians is determined by the composition of raw materials and can be significantly increased due to the rational selection of components, the introduction of enrichments in the recipe, as well as technological processing, which increases their digestibility. Improving the technology of crucifers waffles by increasing their nutrient density will expand the range of products with functional ingredients, and enrichment of the micronutrient composition due to valuable plant raw materials will improve the nutritional value and organoleptic characteristics of the finished product. A line of crustilians with a high content of biologically active compounds has been developed due to the introduction of superfoods such as flax seeds, sesame seeds, sunflower and walnuts and peanuts into the product formulation. It is established that the use of peanuts and walnuts, in the composition, makes the dough less crispy and more fatty. The presence of flax and sesame does not reduce the crunchiness of the finished product, which is characteristic of crustilians, but, on the contrary, slightly increases this figure. It is proved that the index of nutritional density of crustilian made according to the developed recipe in comparison with the prototype is characterized by an increase in the index of nutritional density in three times, while the mass fraction of the macronutrients increases from 1.26 to 2.5 times, depending on the micronutrient. increases only 1.1 times.

Biocorrectors are dry concentrates from natural raw sources with high nutritional value due to the high content of important chemical components of food, including essential, minor, and biologically active nutrients. The raw material for the production of natural biocorrectors can be waste from cutting the fish and animal products. It is promising to use the skin of an octopus, the weight of which during cutting is up to 37% of the weight of raw materials, Pacific herring milt, which is formed during cutting in an amount of up to 12.4% of the weight of raw materials, and bivalve mantle mollusk of Primorsky scallop, accounting for about 10% of its mass. The goal of the research is to obtain dry food concentrates from seafood waste that exhibit functional properties. To preserve and form the specific properties of finished products, namely high biological value, digestibility, organoleptic indicators of concentrates, low-processing temperatures (cryotechnology) were used, which maximally preserved the composition, structure and other natural properties of raw materials. The dry seafood concentrates obtained by cryogenic technology exhibit high functionality and can be used as biocorrectors of food in order to impart high nutritional and biological value to it due to the balance of microand macronutrients.

The use of phytopowders as food additives allows you to create highly nutritious mixtures with a pronounced taste and aroma of fresh fruits and berries. Fruit and berry powders are already used in the production of jelly, fruit drinks, drinks, juices and sauces based on domestic plant raw materials with a high proportion of biologically active substances. The most important phytonutrients of sea buckthorn fruits (Hippophae rhamnoides L.) are carotenoids, flavonoids, anthocyanins, sugars, organic and amino acids, tannins and pectin substances, phospholipids, macro- and microelements. The aim of the research was to study the quality and nutritional value of freezedried sea buckthorn powder. Sublimated sea buckthorn was the object of study (TU 10.39.25-007-0111115841-2018) manufactured by IP A.N. Mazurina (Russia, Kaluga region, Borovsky district, Borovsk). The quality of packaging and labeling, as well as organoleptic characteristics, nutritional value and mineral composition of raw materials have been studied. It was determined that the marking of sublimated sea buckthorn does not comply with the regulated requirements of GOST R 51074-2003 and TR CU 022/2011. Organoleptic characteristics of phytopowder are identified as characteristic of this type of raw material. The actual protein and fat content of the test material does not correspond to the levels stated by the manufacturer. The studied raw materials are distinguished by a variety of chemical composition, namely, the content of protein, carotenoids, vitamins E and A, lipids, dietary fiber, unique trace elements – Al, Co, Cr, Cu, Fe, Li, Mn, Ni, Ti, Zn.
