Abstract: Hydrolysis of proteins in lactic acid bacteria fermented milk produces abundant peptides. Bioactive peptides derived from fermented milk proteins not only have rich nutritional value, but also show many biological functions such as antioxidant, blood pressure lowering, and antibacterial effects. This paper reviews various biological peptides derived from fermented milk proteins with antioxidant, antihypertensive and antimicrobial activities with respect to their mechanisms of action, sequences and structure-activity relationships. Besides, it summarizes the techniques used to identify the sequences and predict the functions of biological peptides. This review will provide a reference for the development and application in functional foods.

Key words: fermented milk, lactic acid bacteria, antioxidant peptide, antihypertensive peptide, antibacterial peptide, peptide sequence
