Chitosan Oligosaccharides / Amino Oligosaccharides, Cos 90%

Amino Oligosaccharides 90% (COS), also known as chitosan, amino oligosaccharides, oligoglucosamine, and chitooligosaccharides. Oligochitosan is an oligomeric glucosamine prepared by degrading animal chitin (shrimp, crab shell, etc.) through bioengineering technology. It is the only basic amino oligosaccharide that exists in large quantities in natural sugars. The relative molecular weight of COS is small, and it has a water-soluble Good sex, safe and non-toxic, easy to absorb, biologically active, has the advantages of anti-oxidation, improving immunity, antibacterial, lowering blood sugar, etc., in health care products, nutrients, food additives, plant growth regulators and feed additives Substances with good application value.
