Chitosan oligosaccharide

Chitosan oligosaccharide, obtained through the decomposition of chitosan, is a deacetylated chitin oligosaccharide, and is a type of oligosaccharide that consists of a chain of multiple D-glucosamine molecules.

The substance takes the form of a pale yellow powder with a distinctive bittersweet taste.
Among its currently known characteristics and features, it
(1) is a saccharide that is not decomposed by enzymes within the digestive organs and is difficult to digest;
(2) has antibacterial properties; and
(3) improves liver function.

Unlike the polysaccharides chitin and chitosan, which are not
water-soluble and therefore have only limited use as additives in food products, chitosan oligosaccharide, like chitin oligosaccharide, is water-soluble, making it suitable for use as an ingredient in food products.
