A kind of cultivation method of cloud fungus with high organic selenium

Abstract

The invention relates to microbial fermentation and edible fungus cultivation, in particular to a cultivation method for cloud ear with high organic selenium. The invention provides a kind of production method of organic selenium cloud fungus fruit body, its total selenium content can be controlled between 0.5~100mg / kg (dry material) according to demand, wherein organic selenium content accounts for more than 99% of total selenium, other Nutrients such as polysaccharides, amino acids, pectin, etc. have been improved to varying degrees, further improving the quality and added value of the fungus fruiting bodies.

Description

A kind of cultivation method of high organic selenium cloud ear technical field The present invention relates to edible fungus cultivation technical field, specifically a kind of cultivation method of high organic selenium cloud ear. Background technique The ecological race of cloud fungus belongs to the black fungus class, and the main place of production is Baise, Guangxi, and is mainly based on the wild semi-wild production mode. Excellent quality, both nutritional and health care functions, rich in functional ingredients such as polysaccharides, pectin, flavonoids, amino acids, etc., are well received by consumers at home and abroad Favored, after more than ten years of experimental research, the "Baiyun No. 6" strain obtained by selection has passed the national new variety certification. " selenium " is a trace element necessary for human body, and it is scientifically confirmed: it is precisely because of the high antioxidant effect of " selenium " that an appro...

Problems solved by technology

[0004] The current production process of selenium-enriched fungi (ganoderma lucidum, shiitake mushrooms, fungus, etc.) has a long cycle (6-8 months), large investment, high technical requirements, low total selenium content, and insufficient organic selenium ratio. Defects, such as patent application CN201210290103.7 (Cultivation method of selenium-enriched fungus using selenium-enriched crop stalks), patent application CN201610138862.X (new technology for organic selenium ganoderma cultivation), patent application CN201910824518.X (a selenium-enriched ganoderma fruiting body and the cultivation method of selenium-enriched ganoderma lucidum spore powder)
