Research progress on extraction technology and biological activity of polysaccharides from Edible Fungi: A review

ABSTRACT

Edible fungus polysaccharide (EFP) is mainly extracted from the fruiting body, mycelium and fermentation broth of fungi. As one of the main bioactive components, EFP has potential health promoting effects. Its extracted polysaccharide has biological activities such as enhancing immunity, anti-tumor, anti-radiation, delaying aging and antioxidation. It has been widely used in food, health products, medicine and other industries. The biological activity of EFP is related to its radical group. The isolation, purification and structure identification are the premise of the bioactivity research and application of EFP. At present, the research on polysaccharides and their structures is helpful to guide and develop their pharmacological effects, biological activities and products. This paper reviews the research status of extraction, purification and structure determination of EFP, such as NMR, methylation analysis and some other methods used in carbohydrate chemical characterization. In addition, the research progress of EFP functional activity and its application in other fields were described, so as to provide basis and reference for the further study of EFP.
