Problems solved by technology

The Guangdong Cordyceps culture medium formula disclosed in the prior art has low active ingredients and low yield, but the biggest problem is that most of the selected raw materials are not listed in the food raw materials or food additive catalogue, such as malt extract, beef extract, etc. The reagents used in the laboratory, if used in the industrial production process, will inevitably be mixed into the finished product during the harvest process, increasing the risk of the product
In addition, the substrate produced by the existing disclosed formula raw materials after fermentation and harvesting can only be used as fertilizer and other low-end markets, which greatly reduces the utilization value of the substrate

Description

technical field [0001] The invention relates to a Guangdong Cordyceps culture medium, which belongs to the field of Cordyceps cultivation. Background technique [0002] China is one of the first countries in the world to recognize edible fungi, and has a long history of edible and medicinal fungi. The cultivation of fungi has been described in early historical documents of our country. Many fungi have good economic and use value. Cordyceps guangdongensis (Cordyceps guangdongensis) is an edible Cordyceps fungus, which is rich in various amino acids, trace elements and vitamins and other nutrients, as well as active ingredients such as adenosine, polysaccharides and cordycepin. Oxidation, enhance human immunity and other pharmacological functions. In 2013, the fruiting body of Cordyceps guangdong was approved by the Ministry of Health as a new resource food, so it is of great significance to actively develop and utilize Cordyceps guangdong. [0003] Cantonese Cordyceps can ...
