<P>PROBLEM TO BE SOLVED: To provide an albumen hydrolyzate richly containing cysteine comprising albumen familiar as food, as raw material, having a higher cysteine content than that of ordinary albumen, and usable as a supply source for the cysteine; and to provide food and drink containing the albumen hydrolyzate richly containing cysteine. <P>SOLUTION: The albumen hydrolyzate richly containing cysteine is obtained by hydrolyzing albumen using papain followed by heating reaction liquid at 65-75°C, hydrolyzing the reaction liquid using at least one kind of protein hydrolyzate enzyme selected from the group comprising trypsin, genus bacillus bacteria-originated protease, Aspergillus filamentous fungus-originated protease and bromelain, and further hydrolyzing the liquid using peptidase followed by heating the hydrolyzed liquid at 75-120°C to eliminate insoluble parts from the liquid so as to contain ≥4.5 wt.% of the cysteine as an amino acid composition per protein. <P>COPYRIGHT: (C)2007,JPO&INPIT |
