Fresh-keeping processing of Coprinus comatus
1. Harvesting classification The suitable period for coprinus comatus harvesting for fresh-keeping exports is the period of mushroom buds, that is, when the stipe is tightly packed with stipe, the bacillus ring is not yet loosened or has just loosened, and the mushroom body 6 to 7 is matured. The harvesting height of the extra-large ECO5 Coprinus comatus is 15 to 20 cm, and that of ordinary varieties is 8 to 15 cm. When harvesting, they are placed separately according to the size of the mushroom, gently and gently, and the stainless steel knife of the mushroom foot is used to cut neatly and cleanly. Requirements no soil, no impurities, no damage, mushroom flower moisture content below 90%. 2. Dehydration and cooling fresh Coprinus comatus export air or sea. The moisture content of air transportation mushroom is required to be below 90%; the water content of sea mushroom is required to be 65% to 70%, and the surface of the mushroom body is not wrinkled. In order to make the water content of Coprinus comatus meet the export requirements, the mushroom body needs to be dehydrated and cooled. The method is: 1 cold air dehydration method: Spread the coprinus comatus, and use a cold air blower to make the coprinus comatus water content meet the standard. 2 drying drying dehydration method: first cockles of dried cockles spread out, hand touch a little dry and then baked with a baking machine, so that the water content of fresh sea mushrooms requirements, avoid baking too dry. 3 Low-temperature drying dehydration method: Add 1 dehumidifier in the high-temperature warehouse, reduce the humidity in the warehouse, and then turn on the fan of the refrigerator, so that the coprinus comatus is dried at low temperature to meet the water content standard. 3. Packing boxes are individually packed in plastic trays according to the size of the mushroom body. Each box has a net weight of 500g. The box is sealed and placed in a refrigerated cartons. Can also be used to store fresh bags, each bag of mushrooms 5kg or 10kg, draw the bag of air, tie bag mouth. Put into the foam box, set the carton outside the foam box and seal the box. 4.

Otherwise, the color of the mushroom body becomes darker, and the mushroom shank incision is blackened and the quality is degraded, which affects sales.
