Abstract

The invention disclose a manufacture method for Chinese caterpillar fungus zymogen powder that includes the following steps: making solid culture medium that made up from the solid materials of 82-88wt% rice, 8-12wt% bran, 3-4wt% soybean meal, and 1-2wt% ammonia sulfate, and adding 0.9-1.1 weight ratio water after crushing the solid material taking sterilization and cooling; fermenting under the condition of asepsis and inoculating onto the solid culture medium for 7-10 days in 20-22 degree centigrade, drying the white hypha in 40-50 degree centigrade and crushing, the product would be gained. The invention is low cost and has high yield.

Description

technical field [0001] The invention relates to a preparation method of cordyceps sinensis fermented bacteria powder. Background technique [0002] With the rapid development of modern medicine and chemical industry, feed additives such as antibiotics, growth-stimulating hormones, insect repellents, and preservatives have been widely used in feed, which has undoubtedly played a huge role in promoting the development of intensive animal husbandry. But at the same time, it will inevitably lead to the residue of chemical drugs in livestock and poultry products, seriously endangering human health. The main manifestations are as follows: First, adding antibiotics to feed for a long time will induce the production of highly resistant microorganisms and superbugs in poultry and livestock. Since these microorganisms have the ability to resist antibiotics, once they infect the human body, the patient will be left without medicine. governance, thus posing a great threat to human bein...
