Chitooligosaccharide is a kind of oligosaccharide, which is composed of N-acetyl-D-glucosamine (≥ 85%) and D-glucosamine (≤ 15%) via β - 1,4-glucoside bond. Chitin can be hydrolyzed by chitin enzyme, which is also called chitooligosaccharide. Gold chitooligosaccharides show that chitooligosaccharides have water-soluble, antibacterial, anti-tumor, and improve biological activities of animals and plants. Due to its special physiological activity and functional properties, it shows broad application prospects in food, medicine, agriculture, cosmetics and other fields.
