Lentinus edodes is a common edible mushroom food. When mushrooms begin to deteriorate, dark spots will appear on the surface and the color will turn taupe or black. In addition, mushrooms will give off an unpleasant rotten smell after deterioration, become soft and sticky, and feel sticky. If you encounter these situations, it means that mushrooms have gone bad and can't be eaten any more.
In order to ensure the safety and hygiene of food, it is recommended to choose fresh and clean mushrooms and store them in a cool and dry place. When cutting mushrooms, it is recommended to use clean knives and seal the rest to avoid bacterial contamination and deterioration.
