Biochemistry Study on Antimutagenic Casein Pepsin Hydrolysis

Abstract

Abstract: Antimutageic activity of casein and its pepsin hydrolysis product were studied with Salmonella Ames test.The digestion products have Shown stronger antimutagenicity against sodium azide than casein.The hydrolyzed peptides formed were separated by ultrafiltration or isoelectroic precipitation,and were characterized by FPLC and Mass spectra analysis.The peptides molecular weigh range was between to 1000 to 2000 dalton.and contained 9 to 11 amino acids.

Key words: Casein , Antimutagenicity , Pepsin, FPLC , Mass , spectra
