The effect of various domestically produced proteolytic enzyme preparations on the organoleptic properties of pea protein isolates

The work investigated the effect of four enzyme preparations (EP): Bacillolysin, Agroprot, Protozyme and Protozyme C (Russia), on smell, taste, as well as protein and peptide profiles of protein isolate isolated from Focor peas. It has been shown that enzyme treatment improves the odor characteristics of the isolate. Thus, it was possible to significantly reduce the severity of bean and herbal smell. At the same time, enzyme treatment also improved the taste of the isolate: it was possible to significantly reduce the severity of such disturbing flavors as legume, astringent, bitter and herbal. The results obtained made it possible to select EP (fungal acidic aspartate proteinase) to improve the organoleptic parameters of pea protein isolates intended for the manufacture of analogues of meat and dairy products.
