Method for preparing cell wall polysaccharide by utilizing ganoderma lucidum spore powder raffinate and product and application thereof

Abstract

The invention provides a method for preparing cell wall polysaccharide by utilizing ganoderma lucidum spore powder raffinate and a product and application thereof, and the method comprises the following steps: carrying out wall-breaking treatment on the ganoderma lucidum spore powder raffinate to obtain wall-broken ganoderma lucidum spore powder raffinate; carrying out extraction treatment on the wall-broken ganoderma lucidum spore powder raffinate, and carrying out solid-liquid separation to obtain an extracting solution; standing the extracting solution, and then carrying out solid-liquid separation to obtain supernate; sequentially carrying out primary centrifugation and secondary centrifugation on the supernate to obtain centrifugate; and concentrating the centrifugate, and drying to obtain the cell wall polysaccharide. The ganoderma lucidum spore powder raffinate is recycled, the utilization rate of the ganoderma lucidum spore powder raw material is increased, and the prepared polysaccharide is cell wall polysaccharide with good moisturizing activity, can be used as a high-quality raw material of various chemical products and has good economic benefits.

Description

technical field

[0001] The invention belongs to the technical field of edible fungus extraction, and relates to a method for preparing polysaccharides and its products and applications, in particular to a method for preparing cell wall polysaccharides from Ganoderma lucidum spore powder extract and its products and applications. Background technique

[0002] Ganoderma lucidum is the treasure of traditional Chinese medicine. It has the function of nourishing and strengthening. The polysaccharides in the spores of Ganoderma lucidum and the polysaccharides in the fruiting body of Ganoderma lucidum are different in structure, and their efficacy and effect are also different. Ganoderma lucidum spores are oval germ cells produced during the growth and maturity stage of Ganoderma lucidum. They contain all the genetically active substances of Ganoderma lucidum. The active ingredients are mainly polysaccharides, triterpenoids and factors related to life metabolism. Modern research sh...
