Chitosan Oligosaccharide(COS) Food Grade is a light yellow powder,Chitosan oligosaccharide (COS) is is a degradation product of chitosan/chitin via chemical hydrolysis or enzymatic degradation involving deacetylation and depolymerization processes. Chitosan oligosaccharide has the advantages of low molecular weight, good water solubility, high function, easy to be absorbed by the body and high bioactivity. At the same time, it has the characteristics of pure nature, no radiation, no pollution and no addition.
Chitosan Oligosaccharide(COS) source from snow crab and red crab shell as raw materials to strictly control other impurities.
(1) Chitosan oligosaccharides are used in the food field as an active agent for intestinal probiotics such as Bifidobacteria to enhance the absorption of calcium and minerals.;
(2) Chitosan oligosaccharides can be used as natural preservatives, instead of sodium benzoate and other chemical preservatives.
Degree of deacetylation: 90%
Particle Size:100 mesh
