How long should fresh shiitake mushrooms be stored in the refrigerator

Fresh shiitake mushrooms can generally be stored in the refrigerator for 3-5 days, and frozen storage can be extended to about 1 month. The actual storage time is affected by factors such as storage method, initial state of shiitake mushrooms, and temperature stability. Fresh shiitake mushrooms have high moisture content and delicate tissues, so they should be kept dry and breathable when refrigerated. Wrap unwashed shiitake mushrooms in kitchen paper and place them in a fresh-keeping bag. Leave a gap at the opening of the bag to reduce the accumulation of condensation water. Controlling the refrigeration temperature at around 4 ℃ can delay spoilage, but it is necessary to avoid mixing with strongly scented foods. If there are sticky or black spots on the surface of shiitake mushrooms, it indicates that they have started to spoil and should not be continued to be consumed. Freezing storage can significantly extend the shelf life, but it can alter the taste. Slice or blanch the shiitake mushrooms whole, drain them, pack them in sealed bags to remove air, and freeze them at minus 18 ℃ for a longer period of time. Thawed shiitake mushrooms are suitable for stewing or frying, and are no longer suitable for cold mixing or steaming. It should be noted that repeated freeze-thaw cycles will accelerate quality deterioration, and it is recommended to pack according to needs.

When making daily purchases, it is recommended to choose fresh mushrooms with tight mushroom caps, white gills, and short and thick stems, as these mushrooms have better storage resistance. Regularly check the status during storage, and discard immediately if mold or odor is found. For mushrooms stored for a short period of time, you can try drying them to remove some moisture and then refrigerating them, or making them into processed products such as mushroom sauce or oil soaked mushrooms to extend their shelf life. Reasonably plan the consumption amount and try to finish it within the best tasting period.
