Abstract

The invention disclose an artificial north aweto culture medium, which contains 33-38g of rice, 9-11g of milk, 17-23g of beef peptone, 0.45-0.55g of potassium dihydrogen phosphate, 4.5-5.5g of pearl powder, 0.25-0.35g of turtle shell powder, 0.25-0.35g of vitamin B1, 0.25-0.35g of vitamin B2, 0.25-0.35g of vitamin C, 0.25-0.35g of vitamin E2, 20-30g of sucrose, 6-10g pupa powder, and 800-1,200g mineral water. The north aweto culture medium and the preparation method thereof have the advantages of high cordyceps conversion, good quality and high yield. The physical and chemical results show that the north aweto contains 2.89% of cordycepin, 8.22% of cordycepin essence, 15.35% of cordycepic acid and 587.85u / mg of SOD enzyme activity, and the contents of north aweto are all higher than that of the natural aweto.

Description

technical field [0001] The invention relates to a formula and a preparation method of an artificial culture medium of Cordyceps militaris. Background technique [0002] At present, the quality of Cordyceps militaris produced at home and abroad varies. Some Cordyceps have a beautiful appearance, but the content of active ingredients is very low, and some also contain heavy metals and pesticide residues. There are four main factors: 1. Strain 2. The formula of the culture medium has not been improved, which cannot fully meet the growth needs of Cordyceps militaris; 3. There are defects in production management; 4. Raw materials are not strictly selected. For the culture medium, Shenyang Zhongtian, Jilin Real Estate Research Institute, Shanghai Academy of Agricultural Sciences and other units have been producing in China, which mainly use the following culture medium: [0003] 1. Magnesium sulfate 0.3g; potassium dihydrogen phosphate 1.25g; potassium chloride 0.5g; iron sulfat...
