How to store oyster mushrooms

Keep them fresh longer

Here’s how. Place whole, unwashed mushrooms in a brown paper bag and fold the top of the bag over. Then stick the bag in the main compartment of your refrigerator. This works because the bag absorbs excess moisture from the mushrooms so they don’t get soggy or moldy.

Oyster mushrooms can be blanched or fried prior to freezing, but note that if they are fried, the mushrooms will forever carry the flavor of the fat you cook them in which may not jive well with certain food applications. Allow the mushrooms to cool and then pack into freezer bags and place in a freezer.

They’ll stay fresh for 5-7 days if you keep them refrigerated. Store bulk mushroom in a paper bag. If you purchase Ostrom’s oyster mushrooms in our shrink-wrapped package, it’s a good idea to remove the plastic wrap from packaged oyster mushrooms, open up the top and cover loosely with a paper towel.

The shelf life of oyster mushroom was about 8-11 days at 0 °C, about 4-6 days at 5 °C, about 2-3 days at 10 °C and about 1-2 days at 20 °C. During storage, film packaging prevented or retarded the deterioration of mushroom appearance, texture and discoloration.

Properly stored cooked mushrooms can last for up to 10 days in the fridge.
