Description

technical field

[0001] The invention relates to the field of K-carrageenan oligosaccharides, in particular to a method for preparing K-carrageenan oligosaccharides with antioxidant activity. Background technique

[0002] As a natural marine sulfated polysaccharide with unique structure, carrageenan is called heparan-like polysaccharide, and its biological activity has become a hot spot in the field of polysaccharide research. In recent years, the biological activity of carrageenan in physiological and pathological research has been discovered one after another. Experimental studies have shown that carrageenan has biological activities such as anti-angiogenesis, anti-tumor, immune regulation, anti-oxidation, antibacterial, anti-virus, and hypoglycemic. However, due to the large molecular weight of carrageenan polysaccharide, poor solubility and absorption, complex structure and other reasons, its application is limited. The molecular weight of carrageenan oligosaccharides i...
