Problems solved by technology

[0004] During the artificial cultivation of Cordyceps sinensis, the fermented mycelium generally only accounts for about 3% of the total fermented product, and the remaining 97% of the fermented liquid is discarded as waste liquid. After analyzing the components of the fermented liquid, it is found that The fermentation waste liquid of Cordyceps polysaccharide contains various proteins, amino acids, vitamins, D-mannose, ergosterol, and trace elements. If the waste liquid of Cordyceps fermentation is directly discarded, it will not only waste resources, but also cause environmental pollution

Abstract

The invention relates to a recycling method for cordyceps sinensis fermentation waste liquid. According to the recycling method, waste liquid generated after cordyceps sinensis fungi are subjected to deep liquid fermentation and mycelia are extracted serves as the raw material, the waste liquid is treated, suppressing substances which suppress growth of cordyceps sinensis fungi are removed, substances beneficial to growth and reproduction of cordyceps sinensis fungi are preserved, and the comprehensive good effects that resource waste is reduced, the problem of pollution of fermentation liquid to the environment is solved, and the yield of cordyceps sinensis mycelia is increased are achieved.

Description

technical field [0001] The invention relates to the field of biological fermentation engineering, in particular to a method for reusing the fermentation waste liquid of Cordyceps sinensis. Background technique [0002] Cordyceps sinensis is also known as Cordyceps sinensis, Cordyceps sinensis, and summer grass winter worm. It is a complex of sclerotium in the larvae of the larvae of the ergotaceae plant Cordyceps sinensis parasitic on the larvae of the larvae. It is mainly produced in Sichuan, Qinghai, Tibet, Yunnan and other places. Dig before and after the summer solstice, sun-dried or dried, and used raw. Modern research shows that Cordyceps sinensis has important edible, medicinal and other economic values. Cordyceps is rich in nutrients such as cordycepic acid, cordycepin and various amino acids, and has the effects of dilating trachea, calming, resisting various bacteria, and lowering blood pressure. . In recent years, the United States, Japan, etc. have successive...
