Function of Chitosan oligosaccharide
Chitosan oligosaccharide is made from Chitosan through enzymatic degradation. It is a water soluble powder with high biological activity and low molecular weight.
Chitosan oligosaccharide is a low molecular weight product with good water solubility and high biological activity. It has many unique features such as high solubility that chitosan does not have, fully soluble in water, easy to be absorbed and utilized by organisms, and its effect is 14 times that of chitosan.
Chitosan oligosaccharide powder is widely used in food, agriculture, feed, cosmetics and healthcare product. In food, it is used to promote absorption of nutritions and minerals, and it is also a natural preservative. In agriculture, it is helpful to regulate soil microbiome to maintain soil health. In feed, it is used as additives to improve animal’s immunity. In cosmetics, it is used to relieve skin wrinkles, inhibit bacteria and prevent sunburn, and it can also used in hair care products. In healthcare filed, it may be used to improve immunity.
