Partial hydrolysates of two types potato protein concentrates were produced by four selected food proteases. Commercialy produced (company Lyckeby) protein concentrate and laboratory prepared concentrate from tubers of Ornella cultivar were subjected of enzymatic hydrolysis by Fromase 220TL, Fromase 220XLG, Maxiren XDS (commercialy available forms of chymosin) and Neutral protases from bacterial Bacillus subtilis. Protein profile of hydrolysates was created using SDS-PAGE. All hydrolysates were determined by solubility and antioxidant activity using DPPH method. The main aim of this study was to evaluate the efficiency of digestion potato protein concentrate by these selected proteases. Based on the results, the most effective enzyme used for hydrolysis of PC was Neutral proteases form Bacillus subtilis.
