Pleurotus eryngii is a kind of edible fungus with white fluff. As long as there is no smell, you can eat it with confidence. These white hairs are aerial hyphae, which have no effect on the quality and nutritional components of Pleurotus eryngii. Therefore, when cleaning, you only need to clean up the white hair and then cook normally. If Pleurotus eryngii is placed in the refrigerator for a long time, white fluff increases or mildew spots appear, it can be thoroughly cleaned first, and then disinfected with boiling water.

Pleurotus eryngii will not grow white hair when stored at room temperature for 3-5 days, and it will not grow white hair when stored in refrigerator for 7- 10 days. But the bought Pleurotus eryngii is usually stored in the supermarket for a period of time, which is not very fresh. So it is best to eat it on the day of purchase.

After purchase, wrap it in clean paper and put it in the refrigerator for many days, which will not soften and deteriorate. Don't pack in plastic bags, because it will produce water droplets after a long time, which will easily lead to rot and white mycelium growth.
