Chitosan Oligosaccharide (COS)

Description

Chitosan Oligosaccharide (COS), also known as chitin oligose or Beta-(1,4)-2-acyl-2-deoxy-D-glucan, COS is a unique form of animal cellulose that stands out due to its exceptional property of not generating heat—a rarity in the natural world. Derived from the deacetylation of chitin found in the exoskeleton of shellfish, this food-grade soluble and bioactive polymer is clear to pale yellow in appearance, with minimal taste and odor. It is highly valued for its health-promoting benefits, including enhancing immune responses and promoting the growth of beneficial bacteria, making it an ideal ingredient for various food applications.
