Abstract
The invention discloses a preservation method of cordyceps sinensis, which specifically comprises the following steps: preparing materials, cleaning the surface, disinfecting, washing, sterilizing, drying and preserving by fresh-keeping gas. The invention relates to the technical field of traditional Chinese medicine health product processing, and particularly provides a cordyceps sinensis preservation method.
Description
Technical Field
The invention relates to the technical field of traditional Chinese medicine health product processing, in particular to a preservation method of cordyceps sinensis.
Background
Cordyceps sinensis, a complex of stroma and larva corpse of Cordyceps sinensis parasitizing on larva of insect of Hepialidae, is a traditional rare nourishing Chinese medicinal material, and has effects of regulating immune system function, resisting tumor, resisting fatigue, etc. Because of narrow distribution area, low natural parasitic rate, strict requirements on living environment conditions and the like, the cordyceps sinensis resource is relatively limited. Therefore, the cordyceps sinensis has extremely high economic value.
Because the picking period is short and the picked fresh cordyceps sinensis is difficult to store and transport, the common storage method at present is to directly dry the cordyceps sinensis in the original place of origin after picking, and then package and transport the cordyceps sinensis. However, this method is subject to weather conditions and is inefficient. In the drying process, the water content in the cordyceps sinensis cannot be accurately controlled, so that the nutrient substances and functional activity in the cordyceps sinensis are lost, and the cordyceps sinensis is possibly polluted by other harmful microorganisms.
In order to ensure the economic value and the nutrient content of the cordyceps sinensis, a fresh-keeping method which can ensure the completeness of the cordyceps sinensis and can keep the nutrition of the cordyceps sinensis not to be lost is needed.
Disclosure of Invention
Aiming at the situation, in order to make up for the existing defects, the invention provides a cordyceps sinensis preservation method which can ensure the completeness of cordyceps sinensis and can keep the nutrition of cordyceps sinensis not to be lost.
The invention provides the following technical scheme: the invention relates to a preservation method of cordyceps sinensis, which specifically comprises the following steps:
step one, preparing materials: collecting and digging 48h of Cordyceps sinensis raw material with original mud wrapped on inner surface;
step two, surface cleaning: manually peeling off mud on the surface of the cordyceps sinensis, drying the mud on the surface of the cordyceps sinensis by adopting flowing air at the temperature of 10-20 ℃, cleaning residual mud on the surface by using a brush, removing the residual mud in the gap by using a needle, cleaning the surface of the cordyceps sinensis by using saline, and wiping surface moisture by using a disinfection towel;
step three, disinfection: soaking the cordyceps sinensis with a clean surface in edible alcohol with the mass concentration of 20-30% for 5-10 min;
step four, washing: taking out, washing Cordyceps with flowing water, and air drying at natural temperature;
step five, sterilization: performing irradiation sterilization on the cordyceps sinensis by adopting cobalt-60 or cesium-137;
step six, drying: drying the cordyceps at a low temperature of-3-5 ℃;
seventhly, preserving fresh-keeping gas: and (3) placing the sterilized cordyceps sinensis into a sealed glass bottle, vacuumizing, introducing fresh-keeping gas, and storing the treated cordyceps sinensis in an environment with the humidity of 65-70% and the temperature of-5 ℃.
Further, the brush is a soft brush.
Further, the irradiation sterilization time is 1-5 min.
Further, the fresh-keeping gas comprises the following volume fractions of gas: 50-70% by volume of N220 to 30% by volume of CO210-20% by volume of H25 to 8% by volume of O2And 5-10% by volume of methane.
The invention with the structure has the following beneficial effects: according to the preservation method of the cordyceps sinensis, the surface of the cordyceps sinensis is subjected to primary disinfection treatment by soaking in edible alcohol, and is washed by flowing water, so that the surface of the cordyceps sinensis is cleaned, loss of nutrients of the cordyceps sinensis caused by a conventional high-temperature sterilization method is avoided by ray radiation sterilization, and the preservation degree and the preservation period of the cordyceps sinensis are improved by matching inert preservation gas with a special temperature and humidity environment.
