Abstract: Animal blood, one of the major animal by-products from slaughterhouses, is rich in protein and has high nutritional value. Animal plasma protein can be used in animal feed and food processing as an important protein resource. It has been shown that enzymatic hydrolysates of animal plasma protein, consisting of small peptides and amino acids, can be used as potential food additives, nutritional supplements and health products because of its ease of digestion and absorption in the body and functional properties such as antioxidant activity, angiotensin-converting enzyme inhibitory activity and toxicity reduction. This review summarizes the enzymatic hydrolysis conditions, characteristics and applications of plasma protein hydrolysates, with the hope of offering some references for further researches and applications of plasma protein hydrolysates.

Key words: blood, plasma protein, hydrolysate, amino acids, nutritional supplements
