Technological Bases of Obtaining Protein Feed Products During Processing of Starch-containing Raw Materials for Biotechnological and Chemical Products

Abstract

At present, in Russia, in the conditions of active development of animal husbandry, there has been a sharp increase in demand for protein and protein-carbohydrate feed products. One such product is fodder yeast. The production of fodder yeast can be cost-effective only if carbohydrate-containing secondary raw materials (SRM) are used as a nutrient medium. In Russia, the re-profiling of idle distilleries for the production of chemical products, from plant raw materials through its bioconversion, is gaining momentum. Such products are ethyl acetate, acetic aldehyde, acetic acid, crotonaldehyde, sorbic acid, etc. In their production, similarly to the technology of alcohol, SRM are formed, containing the remains of grain raw materials and microbial biomass. With appropriate processing from SRM, a protein fodder product corresponding to fodder yeast can be obtained. For effective management of the cultivation process, an important aspect is the selection of the strain of the microorganism, as well as the selection of the nutrient medium. The study and analysis of these issues was the main goal of the research given in the article. As a result, qualitative indicators of secondary raw materials from complex grain processing have been determined, and optimal regimes for their water-heat and enzymatic treatment have been established for the production of nutrient media for cultivation of fodder yeast on their basis. The analysis of food protein strains has been carried out, the most promising for the researched nutrient media has been selected for the research. According to the results of cultivation, it is established that the environment most additionally enriched with hydrolyzate of the starch fraction B is suitable for growing the food protein strains to the greatest extent. The best results in the assimilation of carbohydrates and the accumulation of protein showed the strain of Rhodosporidium diobovatum 115, in addition, it has the ability to produce carotenoids, what else more increases the value of feed products produced with its application.
