Salt water soaking: remove the debris from the roots of fresh mushrooms, put them into 1% salt water and soak them for 10-15 minutes, fish them out and drain them, and put them into plastic bags to keep them fresh for 3-5 days. Soak in clean water: Put fresh mushrooms into containers after washing, pour in clean water to submerge the mushrooms, such as floating mushrooms can be pressed with a heavy object. This method is suitable for short-term storage, be careful not to use iron containers, so as to avoid the fresh mushrooms turning black.

If the number of mushrooms is large, you can dry the fresh mushrooms, then put them into non-iron containers, put a layer of fresh mushrooms and sprinkle a layer of salt. This method can keep the mushrooms for more than 1 year.
