Cordyceps militaris nano-selenium and preparation method thereof

Abstract

The invention discloses Cordyceps militaris nano-selenium and a preparation method thereof. The Cordyceps militaris nano-selenium is developed with producing strains Paecilomyces militaris of Cordyceps militaris fruiting bodies; no organic solvent is added during the production process; obtained products cause no safety hazards. The yield of the Cordyceps militaris nano-selenium is high; bioactive substances in Cordyceps militaris are retained intact; the effects of the nano-selenium are synthesized; bioactivity of Cordyceps militaris and bioactivity of the nano-selenium can be comprehensively utilized fully; production cycle is short, no raw material is lost during the production process of products, and no waste is discharged during the production process; the preparation method is high in product yield, simple in process and green. The Cordyceps militaris nano-selenium can be directly taken as health food; the Cordyceps militaris nano-selenium can also be added during the production process of food industry to make health functional foods, so that the application fields of the Cordyceps militaris and the nano-selenium can be broadened.

Description

technical field [0001] The invention belongs to the field of health care products, and in particular relates to nano-selenium from Cordyceps militaris and a preparation method thereof. Background technique [0002] Cordyceps militaris (L.) Link, also known as Cordyceps militaris (L.) Link, belongs to the fungal kingdom Ascomycota, Ascomycetes, Sordariomycetidae, Hypocreales, Clavicipitaceae, and Cordyceps are the type species of fungi of the genus Cordyceps. By 2002, more than 400 kinds of fungi of the genus Cordyceps had been found in the world, of which about 120 were reported in my country, and Cordyceps militaris is distributed all over the world. Cordyceps militaris is a fungal structure composed of sclerotia and fruiting bodies formed by a class of fungi infecting parasitic insect larvae. Its hosts are mainly Lepidoptera Boriidae, Namphidae and so on. In winter, it dwells in the soil, and the fungal mycelium absorbs nutrients and grows in the larvae, and finally kil...
