Increase the Life of Mushrooms
Mushrooms are a unique and often misunderstood fleshy fungi that can bring new interest to a boring dish or serve as a main dish on their own. While cooking with mushrooms is exciting and fun, keeping them fresh is crucial to protecting their flavor and keeping them safe to eat.
How long do mushrooms last?
The shelf life of mushrooms depends on a number of things, such as how old the mushrooms were when purchased as well as the heat and humidity of the mushrooms’ environment. Storing them in the refrigerator is a good way to extend their shelf life, but they can stay fresh even longer depending upon how they are prepared for storage.
Mushrooms carefully stored in the fridge can maintain freshness for 5-7 days. Sliced mushrooms have a shorter shelf life of 2-5 days as they begin to oxidize after being sliced. If you plan to slice your mushrooms, it is recommended that you wait until you are ready to use them before slicing.
It is also recommended that whole mushrooms be purchased rather than pre-sliced. Dr. Catherine Cutter, a respected food specialist, cautions that pre-cut mushrooms may have a greater risk of being infected with a bacteria known as Listeria monocytogenes simply because they are handled more during processing.
How long do mushrooms last in the refrigerator?
There are some ways to gain maximum freshness from mushrooms for an extended period in the fridge. Most culinary experts agree that freshly purchased mushrooms should be removed from their containers and placed in paper sacks or wrapped in paper towels before being placed in the refrigerator.
The reason that paper is a better storage option than plastic has to do with the biological makeup of mushrooms. These tasty tidbits are comprised mostly of water, in fact, mushrooms contain about 90% water as opposed to most vegetables that consist of around 70% water. As we all know, water evaporates and storing mushrooms in plastic means that the water cannot evaporate properly and can make the mushrooms soft and “mushy.” Storing in the paper provides a breathable alternative, allowing the moisture to evaporate and keeping the mushrooms dry and fresher.
Due to the high-water content of mushrooms, do not rinse them before storage.
How long do cooked mushrooms last?
Cooked mushrooms should not be kept longer than three days and should be stored in the refrigerator between 34 and 40 degrees Fahrenheit. However, it is always a good idea to check cooked mushrooms for signs of spoilage or odors if they have been stored in the refrigerator for more than a day.
Do certain types of mushrooms outlast others?
Surprisingly, mushrooms have little variance between types and how long they keep. If kept in the refrigerator in paper containers, whites, portabellas, and other types should stay fresh for the about the same period. While it is recommended that the mushrooms should be used within a day or two, it is possible that they may stay fresh for as long as a week.
Are there tips for purchasing mushrooms to help them stay fresh longer?
The first step in the process is to inspect mushrooms before buying them carefully. Look for discolorations, dark spots and areas of dampness and do not purchase if noted.
Some grocery stores and supermarkets sell mushrooms by the pound in large bins which are an excellent way to purchase them. Shoppers can inspect each mushroom for freshness or signs of age.
Other stores commonly sell mushrooms in cardboard containers sealed in plastic wrap. While this does not afford the visibility as the bins, it is still usually possible to check the mushrooms for signs of spoilage.
Look for firm mushrooms with no discolorations and with caps that are not separated from the stems.
Can mushrooms be frozen for later use?
It is quite possible to freeze mushrooms if they may otherwise spoil before time to use them. The first step is to make sure that the mushrooms are fresh with no soft spots or other blemishes. Chop or dice the mushrooms and spread them out in a single layer on a platter or baking sheet, then freeze for two hours.
After the two hours has elapsed, transfer the frozen mushrooms into freezer containers and place back into the freezer. Frozen mushrooms can keep for six to eight months.
Summing it up
With proper care and preparation techniques, most edible varieties of mushrooms can be kept and enjoyed for maximum periods of time for additions to salads and soups, favorite sauces, or as additions to many main dish recipes when a touch of something special is called for.
