A kind of Cordyceps sinensis liquid culture medium and preparation technology thereof

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.
