High-pressure-free and short-term normal pressure sterilizing method for cordyceps sinensis culture medium

Abstract

The invention relates to the technical field of disinfection and sterilization of materials, and particularly relates to a high-pressure-free and short-term normal pressure sterilizing method for a cordyceps sinensis culture medium. The high-pressure-free and short-term normal pressure sterilizing method for cordyceps sinensis culture medium particularly comprises the following steps of: taking stable chlorine dioxide powder containing 10% of chlorine dioxide as a disinfectant, sterilizing nutrient solution and solid raw materials composed of cordyceps sinensis culture medium in the earlier stage, and carrying out short-term common pressure disinfection and sterilization on the sterilized cordyceps sinensis culture medium. By the virtue of the sterilizing method provided by the utility model, the cordyceps sinensis culture medium can be sterilized without high temperature and high pressure so as to effectively prevent the nutrition of the cordyceps sinensis culture medium from loosing. Even if the normal pressure disinfection and sterilization are carried out, the time of the disinfection and sterilization is short. According to the high-pressure-free and short-term normal pressure sterilizing method, the sterilization time is greatly reduced, and large quantity of energy such as electric energy, coal and fire wood can be obviously saved. By implementing the invention, the operating efficiency can be obviously improved, and meanwhile the operating cost is lowered, thus being worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field of material disinfection and sterilization, in particular to a method for high-pressure-free and short-term atmospheric sterilization of a cordyceps culture medium. technical background [0002] Cordyceps culture medium is mainly composed of various high-protein substances such as rice, wheat, and corn, and some organic substances are added. The composition medium is very rich in nutrients. If the medium is not sterilized to a sterile state, it will be easy to mold, acidify and deteriorate, and the cultivation of Cordyceps will also fail. [0003] Therefore, in the production process of Cordyceps, the medium must be strictly sterilized before the Cordyceps strains are inserted, and then the grass can be cultivated according to the conventional management; therefore, the sterilization of the medium is the key to the cultivation of Cordyceps. [0004] At present, there are two main ways to sterilize Cordyceps...

AI Technical Summary

Problems solved by technology

High-pressure, high-temperature sterilization equipment costs a lot and consumes a lot of energy; in addition, once the medium is sterilized by high-pressure and high-temperature, its nutrients will be lost

Atmospheric pressure sterilization requires low infrastructure requirements, and the nutrient loss of the culture medium through atmospheric pressure sterilization is small; however, the process of atmospheric pressure sterilization is very long, time-consuming and laborious, and consumes a lot of energy
