Problems solved by technology

At present, Ganoderma lucidum is mainly obtained by artificial cultivation, using sporocarp or spore powder as medicine, but artificial cultivation of Ganoderma lucidum has long cycle, low production efficiency, high labor intensity, and is subject to season and environment restrictions. It is vulnerable to pests and diseases, and its quality and output are unstable

Abstract

The invention discloses a production method of a selenium-rich ganoderma lucidum mycelium raw material and relates to the technical field of food microorganism application. According to the production method, a new ganoderma lucidum strain obtained through ultraviolet mutagenesis is adopted to ferment new liquid-state rice bran and wheat bran complete culture media with addition of selenium, cysteine hydrochloride and sodium copper chlorophyllin, rice bran and wheat bran are efficiently converted into the selenium-rich ganoderma lucidum mycelium raw material and more crude extracellular selenium polysaccharide, the production cost is reduced, the yield is increased, and the selenium-rich ganoderma lucidum mycelium raw material with better quality is prepared; the crude extracellular selenium polysaccharide is reserved as a raw material for further deep processing. The low-value rice bran and wheat bran are converted into the selenium-rich ganoderma lucidum mycelium raw material with multiple healthcare functions, and the production method of the selenium-rich ganoderma lucidum mycelium raw material has beneficial social and economic effects in the aspects of production cost reduction, efficient and reasonable low-grade resource utilization and public health protection, thereby having practicability.

Description

technical field [0001] The invention relates to the technical field of food microorganism application, in particular to a method for producing selenium-enriched Ganoderma lucidum mycelia raw material by using a new strain of Ganoderma lucidum obtained by mutagenesis. In the method, the new strain is added with cysteine ​​hydrochloride and copper chlorophyll. Fermentation is carried out in the liquid rice bran whole material new medium of sodium salt and sodium selenite to obtain the selenium-enriched ganoderma mycelia raw material. Background technique [0002] Medicinal and edible fungi have a long history of use in China and a wide range of users. Modern science reveals that the mycelia, fruiting bodies or spores of commonly used medicinal and edible fungi such as Ganoderma lucidum, Hericium erinaceus, Cordyceps sinensis, and Grifola frondosa can produce amino acids, proteins, vitamins, polysaccharides, nucleosides, Various active ingredients such as flavonoids and antibi...
