In the complex processing of pea grain, as well as in the production of groats and flour, a number of wastes are generated, a significant part of which is utilized. The conversion of waste processing to secondary raw materials not only allows for the resolution of environmental problems but also expands the opportunities for raw materials in economic sectors. Pea grain shells, which contain biopolymers, vitamins and minerals, can be considered as one of the sources of raw materials for obtaining sorption materials. The object of the research in this work was the shells isolated from the grain of the Amior and Temp pea varieties of Russian selection. The aim of the study was to investigate the structure, physical properties, and component composition of the pea grain shells, as well as to evaluate the prospects of their use as raw materials for the production of sorbents for the treatment of polluted surface water and wastewater. To determine the quality indicators of pea grain shells, the generally accepted methods were used. The share of shells in pea grain was found to be 7.1-10.6%. The main components in the composition of pea grain shells are polysaccharides, with a predominance of fiber, largely determining the structure and properties of this raw material. Pea grain shells are characterized by low density, good hygroscopicity and moisture retention capacity. The proteins and pectins present in the composition of the pea shells have sorption properties. It is possible to increase the degree of purification of surface and waste water from harmful impurities by using extracts from pea shells containing biopolymers that form insoluble complexes with pollutants.

The process of bioconversion of the secondary product of pea flour processing into protein concentrate (serum) into fodder microbial-plant concentrate has been optimized. For this, a composition was selected from the culture of the fungus Geotrichium candidum 977 and the yeast Saccharamyces cerevisiae 121, a mathematical model of concentrate synthesis was developed in the form of an equation that adequately describes the dependence of the biomass yield on technological parameters: pH of the medium, temperature and amount of inoculum. The concentrate from the biomass had a protein mass fraction of 61.68 % of DS, from the biomass with the culture liquid - 57.90 %. Concentrates - biologically complete, the rate of essential amino acids was 107-226 %, out of 30 fatty acids, 97 % were acids that are part of animal fats, vegetable oils or marine organisms. The ratio of saturated and unsaturated acids is 1:3, the content of trans isomers is 5.1 %, omega-6 fatty acids (linoleic) is 19.73 %. The ability of symbiosis between the yeast S. cerevisiae 84/5 and the fungus Trich. cutaneum 656 has been proven. transform the components of whey remaining after the extraction of phytin from rice bran into protein biomass. The ratio of monocultures by mass fraction is 1:1, pH - 5.0…6.0, duration of growth - 72 hours, digestibility – 90 %. The protein is enriched with methionine, isoleucine, leucine, lysine. The amount of essential acids is 18-21 % higher than in concentrates obtained from individual monocultures. The use of concentrates is advisable to use in the diet of animals.
