Abstract

The invention relates to a cordyceps militaris storing method. The cordyceps militaris storing method comprises the following steps of soaking cordyceps militaris in a citric acid aqueous solution for shaping, performing drainage, spreading the drained cordyceps militaris in a material plate, loading the material plate in a material box of a vacuum freeze drying machine, and when material precooling temperature reaches to minus 40-minus 50 DEG C, maintaining the temperature for 2.0-2.5 hours; performing vacuumizing, when vacuum pressure is reduced to 50Pa or below, beginning to raise temperature, continuing vacuumizing, after the temperature of a material bin rises to 35 DEG C, turning off the equipment, and taking out dried cordyceps militaris so as to obtain freeze-dried cordyceps militaris; and when the freeze-dried cordyceps militaris is eaten, soaking the freeze-dried cordyceps militaris with water for 20-30 minutes so as to obtain freshly eaten cordyceps militaris. After pretreatment through citric acid immersion liquid, dried finished products is low in the frangible degree, long-time storage is facilitated, the dried finished products do not mildew or deteriorate and are not eaten by worms, and the tissue structure and the appearance shape of the dried finished products are well preserved. The rehydration effect of the cordyceps militaris is the best, after rehydration, the immersion juice is golden and clear, the color and the appearance state of cordyceps militaris bodies are similar with those of fresh cordyceps militaris, and the dried finished products can be used as dishes on a dining table to be eaten.

Description

technical field [0001] The invention relates to a storage method of Cordyceps militaris. Background technique [0002] Cordyceps militaris is rich in protein and amino acids, and contains more than 30 trace elements needed by the human body. It is a top-notch nourishing product. With the development of society and the enhancement of people's awareness of health care, the output of artificially cultivated Cordyceps militaris has also increased year by year, but storage and transportation have become problems. If it is not processed in time, it will quickly rot and deteriorate. [0003] Vacuum freeze-drying technology is a better method for food storage and processing, which can retain the color, aroma, taste and nutritional components of food to the greatest extent. The development history of freeze-drying technology in my country is relatively short, and there is a lack of systematic research on the theory of freeze-drying process and related disciplines, and the lack of sy...
