Abstract

The invention relates to a liquid culture medium for cordyceps and a process for preparing the liquid culture medium. The liquid culture medium for the cordyceps comprises, by weight, 5-15% of Jerusalem artichoke extract, 1-5% of oat powder, 3-6% of sorghum husk powder, 2-6% of peptone, 0.01-0.05% of lysine, 0.01-0.05% of glycine, 0.05-0.1% of KH2PO4, 0.02-0.05% of Fe2SO4 and the balance water. The liquid culture medium and the process have the advantages that the Jerusalem artichoke extract is used for preparing the liquid fermentation culture medium for the cordyceps, accordingly, cordyceps fermented products prepared by the aid of the liquid fermentation culture medium are excellent in quality and contain active components with high contents, and the contents of cordycepin, adenosine, cordyceps polysaccharides and cordyceps acid are equivalent to the contents of cordycepin, adenosine, cordyceps polysaccharides and cordyceps acid in natural cordyceps.

Description

technical field [0001] The invention relates to the technical field of edible and medicinal fungus fermentation production, in particular to a liquid culture medium of Cordyceps sinensis and a preparation process thereof. Background technique [0002] Cordyceps sinensis, also known as Cordyceps militaris and Cordyceps militaris, is formed by connecting the insect body and the sub-seat, with a total length of 9 to 12 cm, a dark brown color, and many horizontal wrinkles on the back. The insect body is light and brittle, easy to break, and the cross-section is white.
