The shelf life of unopened mushrooms in the refrigerator depends on the type of mushrooms and their freshness when purchased. In general, here are some guidelines:
Fresh White or Cremini Mushrooms: When properly stored, unopened fresh white or cremini mushrooms can last for about 1 to 2 weeks in the refrigerator.
Fresh Shiitake Mushrooms: Shiitake mushrooms typically have a longer shelf life compared to white or cremini mushrooms. Unopened fresh shiitake mushrooms can last for about 1 to 2 weeks or even up to 2 to 3 weeks in the refrigerator.
Oyster Mushrooms: Unopened oyster mushrooms are generally more delicate and have a slightly shorter shelf life. They can last for about 5 to 7 days in the refrigerator.
Wild Mushrooms: The shelf life of wild mushrooms, such as chanterelles, morels, or porcini, can vary. Generally, unopened fresh wild mushrooms can last for about 3 to 5 days in the refrigerator.
It's essential to check the mushrooms' condition when purchasing them. Choose firm, plump mushrooms with no signs of sliminess or mold growth. Additionally, to extend their freshness, store mushrooms in a paper bag or a loosely closed container to allow for some air circulation while preventing them from drying out.
Always use your best judgment when assessing the freshness of any food item. If you notice any signs of spoilage, such as a foul odor, unusual discoloration, or sliminess, it's best to discard the mushrooms.
If you cannot consume the mushrooms within the recommended time frame, you can consider freezing them to extend their shelf life. Freezing mushrooms can be a convenient way to preserve them for a more extended period, but keep in mind that their texture might change after thawing.
