Fresh possession. Fresh picked Pleurotus ostreatus is difficult to sell in the short term due to market impact, and fresh storage can be used. The time when fresh oyster mushrooms are stored at room temperature is greatly affected by temperature and air humidity. At room temperature of 3-5°C and air relative humidity of 80%, fresh mushrooms can be stored for 1 week. The temperature is higher and the humidity is also increased. When the amount of mushrooms is small, the mushroom can be placed in a cylinder with a small amount of cold water, and the cylinder port can be sealed. Even if the temperature reaches 15-16°C, it can be preserved for about 1 week. The oyster mushroom can also be completely immersed in cold water, but the water must be clean. The iron content of the water should be less than 2 milligrams per liter so that the oyster mushroom will not turn black. refrigeration. Refrigeration refers to a method of preservation that is stored at a temperature close to 0 or slightly higher than a few degrees. The temperature of refrigeration is not as low as possible. Refrigeration can be carried out in refrigerated rooms and refrigerators. During the refrigerating process, the air temperature inside the cabinet must be checked frequently. The storage time should be controlled within 7 days. The method of freezing preservation is to treat the fresh oyster mushroom body in boiling water or steam for 4-8 minutes, rapidly cool in a 1% citric acid solution, drain the water, pack it in a plastic bag, and store it in a cold room. When the amount is small, it can be stored in the refrigerator and can be kept fresh for 3-5 days. Atmosphere storage. After harvesting, fresh mushrooms are still undergoing respiration, absorbing oxygen and releasing carbon dioxide. Appropriately reduce the concentration of oxygen in the environment, increase the concentration of carbon dioxide can inhibit the respiration, extend the shelf life, Pleurotus ostreatus at low temperatures can withstand 25% of the carbon dioxide concentration. In the modified atmosphere room, from the normal composition of the closed air to the required gas index, there is a process of reducing oxygen and increasing carbon dioxide. The shorter the oxygen reduction period is, the better, so that the stored mushroom body can quickly escape from high oxygen and the environment. The best air conditioning effect. Chemical storage. Chemicals that can be used to store Pleurotus ostreatus are mainly 0.1% sodium metabisulfite, 0.6% sodium chloride, 4 milligrams per litre of a solution of triacontane, 50 milligrams per liter of anthraquinone solution, and 0.05% potassium permanganate. Aqueous solution, 0.1% oxalic acid and so on. The specific method is: first fresh and clean mushrooms, put into the liquid soak for 1-5 minutes, remove and drain water, divided into 0.03 mm thick plastic bags (polyethylene), tie the bag for storage .
