Technology for culturing bird-sourced cordyceps

Abstract

The invention provides a technology for culturing bird-sourced cordyceps. The technology for culturing the bird-sourced cordyceps is characterized by comprising the following steps: 1, culturing strains: (1) collecting wild cordyceps strains, performing sexual reproduction, rejuvenation, acclimation and germination to obtain cordyceps female parent, and storing the pure cordyceps strains for later use, (2) culturing regeneration female parents, and (3) culturing liquid strains; 2, selecting bird eggs as hosts, and sterilizing the bird eggs; 3, inoculating; 4, culturing: (1) culturing in contamination period, (2) culturing in veraison period, and (3) culturing in germination period, wherein the process of culturing in germination period is carried out in earlier, middle and later stages; till completion of the culture, the culture time for completing one growth cycle of the bird-sourced cordyceps is about 100 days. The culturing method is simple in operation and is suitable for large-scale production; active components of the cultured cordyceps are not less than those of natural cordyceps; the cultured cordyceps has good taste and can be directly eaten as food.

Description

technical field

[0001] The invention relates to a process for cultivating Cordyceps with high-protein poultry eggs with reproductive function and edible standards, and belongs to the technical field of bioengineering for artificially infecting poultry eggs with Cordyceps fungus to cultivate Cordyceps. Background technique

[0002] Cordyceps sinensis is a traditional precious nourishing Chinese herbal medicine, which belongs to the phylum Fungi, Ascomycetes, Hypocreales, Ergotaceae, and Cordyceps. According to modern research results of pharmacology, Cordyceps sinensis contains about 7% of cordycepic acid, 28.9% of carbohydrates, about 8.4% of fat, about 25% of protein, and 82.2% of fat is unsaturated fatty acid. In addition, it also contains vitamin B12, ergosterol, Six-carbon sugar alcohols, alkaloids, etc., have various effects such as regulating immune system function, anti-tumor, and anti-fatigue.

[0003] Cordyceps sinensis was mostly wild in the past. With the increas...
