Preservation method of Lentinus edodes:

1. Refrigeration and preservation: Refrigeration equipment for fresh mushrooms includes refrigerators, freezers, cold storage and refrigerated trucks. The refrigeration temperature is inversely proportional to the storage time, that is, the lower the refrigeration temperature, the longer the storage time. It has a low temperature limit, which will cause metabolic abnormality and weaken the resistance to adverse environment. Generally, the temperature of cold storage is controlled at 0- 10℃ and the storage time is 7-20 days. It can be stored at 4-5℃ for about half a month;

2. Plastic bag packaging preservation: This preservation method has the advantages of easy material acquisition, convenient storage, low cost, sanitation and beauty. Now it has been widely used in the storage, transportation and retail of fresh mushrooms. Low density polyethylene (LDPE) is the best film material with a thickness of 20-70 microns. Small bags are usually used in the market. Select 6-7 sub-cooked fresh mushrooms, 200-300g in each bag, then tie the bag tightly or seal it by heat sealing, and then refrigerate. It can be kept fresh for 5 days and 22 days at 20℃, 65438 07℃ and 65438 0℃. It can basically meet the fresh-keeping requirements of fresh mushrooms in the market.
