Bioconversion of Cereal Serum - A Secondary Product for Producing Protein Concentrates From Pea and Chick Peas

Abstract

Studies on the bioconversion of whey water formed from chickpea and pea grains in the preparation of protein concentrates have been performed. The serum remaining after precipitation of the main part of the protein was subjected to a symbiotic transformation of Saccharomyces cerevisiae 121 and Geotrichum candidum 977 yeast cultures with the formation of protein-containing products with a mass fraction of protein (52.27-57.90% of DS) and a complementary amino acid composition. A microbial-plant concentrate was used as an additive in the feeding of Wistar laboratory rats. After 25 days of feeding, there was no negative effect on the physiological parameters and behavior of animals, which indicates the high quality of the protein product and the prospects of its inclusion in the composition of animal feed and diets.
