摘要：In this study, changes in proteolysis level of Ezine cheese was investigated during ripening period. The rates of water soluble nitrogen, 12% trichloraceticacid soluble nitrogen and 5% phosphotungustic acid soluble nitrogen were determined and electrophoretic analysis was carried out during one-year ripening period. While total nitrogen level did not change, the rates of nitrogen fractions increased significantly during ripening . The results of electrophoretic analysis showed that degradation of b-casein fraction was slower than αs-casein fraction during storage.
