Natural Ingredients

Chitosan is a natural biopolymer produced by the deacetylation of chitin, a major component of the shells of crustaceans such as crab, shrimp, and crawfish. Although chitosan is known to have important functional activities, poor solubility makes them difficult to use in food and medicinal applications. Chitosan oligosaccharides (COS), also called oligo chitosan or chitooligosaccharides, are normally enzymatic products hydrolyzed from chitosan. Because of its water solubility, COS has attracted the interest of many food and nutrition researchers. Recent studies1,2 indicate that the advantages ofCOS include antimicrobial, hypocholesterolemic, immunityenhancing properties. COS accelerates calcium and iron absorption, and therefore can be useful in the delivery of drugs.

COS has antitumor, anti-inflammatory, radio-protective, and antioxidant properties. COS can exclude toxins from the intestines, reduce heavy metal poisoning, as well as prevent tooth decay and tooth-related diseases. In spite of all these benefits, unstable and expensive enzymatic processing and purification steps make COS cost-prohibitive for many applications. Moreover, its astringent taste prevents any wide adoption by the beverage industry.
