Abstract:

As the most abundant protein in animals, collagen and its hydrolysates are biocompatible and biofunctional
due to the unique triple-helix and amino acid sequence, and have been widely used in many fields. In this article, we have
summarized the bioactive functions of collagen hydrolysates according to the latest investigations at home and abroad,
including antimicrobial properties, antioxidant activity and antihypertensive activity. The development of collagen industry
should not be limited to medicinal materials and tissue engineering. Food and health products based on collagen and its
hydrolysates should also be developed.

Key words: collagen hydrolysates, antimicrobial properties, antioxidant activity, antihypertensive activity
