The main results of scientific research of the KRISPAP � branch of FSBSI NCFSCHVW, obtained in 2022 by scientists of the Institute in the implementation of the State Task in 4 scientific areas within the framework of the implementation of 2 complex topics, as well as data reflecting publication effectiveness and patent-licensing activity are presented. Research work was carried out in accordance with the PFSR in the Russian Federation for the long-term period (2021-2030) in the direction of: 4.4.1 Storage and processing of agricultural products. Ensuring the priorities of the PFSR in the Russian Federation for the long term (2021-2030) provides for the need to conduct scientific research, the purpose of which is to identify patterns and mechanisms of the controlled transformation of pressed beet pulp, phospholipid concentrates � liquid lecithins and tomato pomace using physical, physical and chemical and biotechnological methods aimed at regulating the properties, formation of the quality and safety of complexes of food pectin-containing fibers, phospholipids and carotenoids, and based on the identified patterns, the development of resource-saving technologies for their production, as well as scientific research aimed at identifying the patterns of development and interaction of producer strains biological preparations and pathogenic microorganisms (bacterial and fungal nature) that reduce losses from microbiological spoilage of zucchini, eggplant, garden carrot, white cabbage and leafy vegetables for development of resource-saving storage technologies based on the identified patterns. The results of scientific research were published in peer-reviewed journals � 31 scientific articles, including 8 articles in journals included in the core of the RSCI, 16 articles in journals included in the list of the Higher Attestation Commission under the Ministry of Education and Science of the Russian Federation, 5 articles in journals indexed in international information and analytical citation systems Web of Science and Scopus. 8 articles have been published in the materials and collections of International Scientific and Practical Conferences. 1 instructional medium and 2 recommended practice also published. Based on the results of scientific research, 4 patents of the Russian Federation for inventions and 3 certificates of registration of computer programs were received, as well as 5 applications for alleged inventions were submitted to FIIP.

The main task of agricultural production, in particular crop production, is to meet the needs of the population for fresh fruits and vegetables of high quality. The successful solution of this problem largely determines the standard of human life and health, which is currently of great importance. However, worldwide consumption of crop production per capita is 20-50 % lower than the minimum recommended levels despite its nutritional and functional value. The main reason for insufficient consumption is quantitative and qualitative losses in the system of production, storage and sale. According to FAO, losses of crop Production from the total food losses are up to 45 %. In this regard, along with increase in the production of agricultural products, there is a question of improving their quality � it is necessary to improve not only the production, but also the storage of major types of agricultural raw materials. In this connection, it is strategically important to ensure the safety of crop products during storage and sale, which is reflected in the �Concept of state policy in the field of healthy nutrition of the population of the Russian Federation�, which provides for comprehensive research in improving storage and processing technologies for fruits and vegetables. On this basis, the purpose of this work is to review the available scientific and technical information on existing methods of storage of fruit and vegetable products. As a result of the analysis of scientific and technical information, we can conclude that promising directions for improving the technology of storage of agricultural products are the use of regulated gas environments, bioactive packaging and coatings, which helps to extend the shelf life with minimal losses. The proven effectiveness of the described methods of extending the shelf life of crop products suggests the relevance of developing new storage technologies using a complex of biotechnological and physical methods.

The study and generalization of world experience in research on the development of technologies to reduce losses, stabilize the quality and maximize the preservation of biologically active substances of crop products during storage, made it possible to conclude that research on the methodology for the application of electromagnetic fields of extremely low frequencies (EMF ELF) is relevant. to control the development of pathogenic microflora, leading to the development of diseases and, as a consequence, the loss of crop production. During the study, the composition of the microflora of strawberries was studied, it was found that the amount of mesophilic aerobic and optionally anaerobic microorganisms (MAaOAM) on the berries of the strawberry variety �Marmalade�, the harvest of 2019, ranged from 5000 CFU/g to 12000 CFU/g. MAaOAM are mainly represented by spore microorganisms, enterobacteria and yeast. The number of molds is from 110 CFU/g to 1400 CFU/g. The influence of EMF treatment by electromagnetic fields on the pathogens of strawberry fungal nature was investigated. In the samples treated with EMF ELF, in comparison with the control sample, the number of microorganisms after 14 days of storage was lower. The regularities of the influence of the EMF ELF processing parameters on the development of pathogenic microorganisms of strawberries in experiments and in vivo were revealed. It was established that the processing of strawberries of the variety �Marmelada� using ELF EMF with parameters: frequency � 30 Hz, current strength � 10. A, processing time � 30 minutes has the maximum inhibitory effect on the development of phytopathogenic microorganisms Botrytis cinerea and Rhizopus nigricans.

The article presents the results of studying the influence of some types of packaging materials used in conjunction with an ethylene absorber on ethylene production intensity of zucchini cv. Alexandria and tomatoes cv. Inkas during storage for 14 days at a temperature of 8 � 10 �� and air relative humidity of 90�3 %. The study was carried out using StePac Xtend bags, creating a modified atmosphere, and Inter Fresh ethylene absorbers (sachets); one sachet for ethylene absorption was placed in Xtend bags. It was found that when stored under these conditions the ethylene concentration in Xtend bags was 80% lower in case of zucchini and 1600 % lower in case of tomatoes than when using traditional bags, even despite the higher initial mass of produce in Xtend bags. In zucchini and tomatoes extracted from bags, the rate of ethylene production was also lower after storage in Xtend bags, than when using traditional bags: 111,1 % lower in case of zucchini and 211,5 % lower in case of tomatoes. Losses associated with microbiological spoilage were not observed during the experiment.

One of the most important vegetable crops in Russia is cabbage, which includes a number of varieties, including cauliflower. The content of vitamin C, carbohydrates, proteins, acids and minerals in cabbage determines its value as a food product. Currently, one of the areas of research aimed at developing new effective, economical and environmentally friendly echnologies for storing vegetable juicy raw materials is the use of various types of physical treatment, including electromagnetic fields. This article presents the results of studying the influence of extremely low frequency electromagnetic fields the content of water, fiber, soluble carbohydrates (sugars and starch), protein and vitamin C in the cauliflower cultivar of Ardent during storage. The objects of research were treated with an electromagnetic field (25 Hz, 10mT, 30 min) in a laboratory experimental setup and were stored for three weeks at a temperature of 4�1 º� and air relative humidity of 75�3 %. It was found that, in comparison with the control, the ELF EMF treatment of cauliflower leads to a slightly more active loss of water, and is also ccompanied by a decrease in the mass fraction of cellulose by an average of 5.3 % and an increase in the mass fraction of soluble carbohydrates by 18.1 %, protein by 4.6 % and vitamin C by 14.4 % during storage. The study of the regularities of the influence of the treatment of vegetable juicy raw materials with electromagnetic fields of extremely low frequencies on the biochemical composition can make it possible to develop new storage methods.
