The Effect of Various Domestically Produced Proteolytic Enzyme Preparations on the Organoleptic Properties of Pea Protein Isolates.

The effect of four enzyme preparations (EP), Bacillolysin, Agroprot, Protozyme, and Protozyme C (Russia), on the protein and peptide profiles of the protein isolate isolated from peas of the Focor variety, as well as on its smell and taste, was investigated in this work. It was shown that enzyme treatment can improve the odor characteristics of the isolate. Thus, it was possible to reduce significantly the severity of the bean and herbal smell. At the same time, enzyme treatment also improved the taste of the isolate: it was possible to reduce significantly the severity of disturbing flavors such as leguminous, astringent, bitter, and herbal. The results obtained allowed us to select EP (fungal acid aspartic protease) to improve the organoleptic parameters of pea protein isolates intended for the production of meat and dairy product analogs.
