Extraction of nutraceuticals from shrimp by-products

Abstract

© 2013 by Taylor & Francis Group, LLC. Nutraceuticals-foods with medical-health benefits beyond their basic nutritional function-are of increasing interest for the prevention and treatment of disease. Marine products are good sources of nutraceuticals with antimicrobial, antioxidant, immunoenhancing, antitumor, and anti-inflammatory activities (Table 10.1). The majority of the nutraceuticals have multiple therapeutic benefits. The nutraceuticals chitin, chitosan, glucosamine, carotenoids (mainly astaxanthin), and carotenoprotein have been extracted from shrimp, crab shells, and squid pens (Shahidi, 2005). Collagen, gelatin, peptides, and unsaturated essential fatty acids can be extracted from fish.
