Summary

This chapter mainly focuses on proteins, peptides, amino acids and protein hydrolysates from seafood and crustacean waste. Fish skin and bones can be used as sources for the extraction of collagen and gelatin. Extraction is an important process in the food, flavor, fragrance and pharmaceutical industries, allowing beneficial natural compounds to be collected from many plant and animal sources. There are many methods by which to hydrolyze proteins into their components, including chemical (acid and alkaline hydrolysis), biological (lactic acid fermentation, enzymatic hydrolysis and autolysis) and physical (microwave and ultrasound extraction). Protein hydrolysates and bioactive peptides isolated from various marine wastes have shown numerous bioactivities, such as antihypertensive, antithrombotic, immunomodulatory and antioxidative activities.
