Problems solved by technology

[0004] At present, the extraction technology of edible fungus polysaccharides is generally divided into two types, one is to extract from the edible fungus fruit body by leaching or enzymatic hydrolysis, and the other is to extract from the edible fungus mycelium. Both of the above two methods have polysaccharide extraction. Low rate of technical issues

Abstract

The invention particularly relates to an edible fungus polysaccharide extraction method, an edible fungus polysaccharide and an edible fungus beverage, and relates to the technical field of edible fungus effective component extraction. According to the edible fungus polysaccharide extraction method provided by the embodiment of the invention, an edible fungus strain is trained, and the trained edible fungus strain is subjected to fermentation culture by adopting a culture medium prepared from edible fungus sporocarp powder. The edible fungus strain obtained through acclimatization is high-quality strain and is inoculated into the culture medium prepared from the edible fungus sporocarp powder, and fermentation and reproduction of edible fungus thalli are facilitated. Almost no harmful substances are generated in the fermentation process, the fermentation period is short, the extraction efficiency and the extraction amount of the edible fungus polysaccharide can be remarkably improved,and the shelf life of an extracted polysaccharide liquid beverage can be remarkably prolonged. Meanwhile, the polysaccharide extracted by the method provided by the embodiment of the invention generally exists in a small molecular state, and is beneficial to rapid absorption and utilization for a human body. The method has positive popularization significance.

Description

technical field [0001] The invention relates to the technical field of extraction of effective components of edible fungi, in particular to a method for extracting edible fungus polysaccharides, edible fungus polysaccharides, and edible fungus beverages. Background technique [0002] Edible fungi, also known as edible (medicinal) fungi, are a type of large edible (medicinal) fungi with high edible and medicinal value. The common types of edible fungi used for health care and disease prevention in my country mainly include: Hericium erinaceus There are more than 20 kinds of mushrooms, shiitake mushrooms, frondosa, white fungus, Coprinus comatus, black fungus, militaris sinensis and Ganoderma lucidum, etc. These edible fungi are rich in biological polysaccharides, such as polysaccharides, polypeptides, nucleosides and triterpenes etc. It has been proved by scientific experiments that these biological polysaccharides have various functions such as anti-oxidation, anti-tumor, lowe...
