摘要: Abstract The free amino acids and sulphosalicylic acid-soluble N fraction in the French ewes’-milk cheese, Ossau-Iraty, were determined to evaluate degree of proteolysis during ripening cheese. RP-HPLC was used assess acids, trinitrobenzenesulphonic acid method fraction. total content as by ranged from 200 mg/100 g dry matter on first day 2200 after 120 d ripening. major glutamic acid, asparagine, glutamine, valine, leucine, phenylalanine lysine, which accounted for between 50% (on 1) 70% 120) acids. Correlations all main time good. Regression yielded a correlation coefficient value 0.985.
