How long can mushrooms be stored in the refrigerator and freezer? Storage periods and rules

Mushrooms are very tasty gifts of nature, which contain many useful substances. If you cook and eat them correctly, they can only be beneficial for the body, but otherwise they can cause significant harm. That is why it is so important to know how best to preserve mushrooms brought from the forest in a basket or bought at the market or in a store. If stored improperly, mushrooms spoil too quickly, and even the most delicious of them can become dangerous. Therefore, when the next mushroom season begins, the question arises again and again, how many days can mushrooms be stored in the refrigerator?

Is it possible to store mushrooms?

First, you should figure out whether it is possible to store such “vegetable meat” at all.

Experts classify mushrooms as perishable foods. They, like any other plant matter, without receiving nutrition, soon begin to die, that is, to decompose and rot. At the same time, mushrooms release toxic substances that are dangerous to health. This can happen within a few hours after cutting. It is almost impossible to stop the decay process. But under certain conditions, there is a chance to keep mushrooms fresh for 3 days or even longer.

Storage conditions

There are several rules that, if followed, will slow down the decomposition process and prolong the freshness of plant-based meat.

1. The most important condition is coolness. The ambient temperature should not be high. For mushrooms, temperatures of 20 degrees and below are permissible.

2. The second most important rule is the absence of light sources. If they are directed at the fruit, then this can be equated to warm storage. The best solution is to leave the mushrooms in a dark place.

3. Another enemy of plant-based meat is high humidity. It only provokes the process of decay.

So, how to keep porcini mushrooms and any other species fresh for several days? They should be left in a cool, dark place with relatively low humidity.

Common storage errors

Such a fastidious product to store as mushrooms often begins to deteriorate ahead of time - within a day after collection and processing. This may be due to many factors related to improper preparation and storage of the product.

The most common mistakes made during storage are:

  • Store in tightly tied plastic bags. Due to the release of condensation, the contents of bags without periodic ventilation quickly begin to rot and deteriorate.
  • Store open in the refrigerator next to strong-smelling foods. Mushrooms quickly absorb the odors around them, losing the richness of their aroma.
  • Storing mushrooms of the same variety together. They have different storage characteristics, as well as excellent shelf life, so mixing them is not recommended.
  • Adding insufficient vinegar to the marinade. In this case, it will not be possible to preserve the contents of the jars for a long time.
  • Neglecting recommendations for pre-soaking the crop in a saline solution. It is this stage that often helps to preserve the mushrooms in their previous state for a long time, avoiding their spoilage.

Features of storing store-bought mushrooms

If you purchased mushrooms in original packaging, you should follow the dates indicated on the container itself. Ideally, this should be a vacuum bag, then the product is guaranteed not to deteriorate within a month, as the manufacturer claims. It is recommended to leave the product in the same packaging. But it’s better to play it safe and store mushrooms for no more than 3-5 days.

Trays simply covered with film can usually be stored for up to one week. But in fact, the process of decomposition under polyethylene begins much earlier. In this case, it will not be possible to keep the mushrooms fresh for more than 2-3 days. Therefore, it is better to transfer them to another bowl. Which one exactly will be discussed a little later.

Store-bought mushrooms are usually clean, but before cooking they should be rinsed with running water, dried on a paper towel, and all yellowed parts removed. The product should be used immediately, maximum within two to three hours.

How to determine and what to do with delays

In order to distinguish a high-quality fresh product from an unsuitable one for food, you need to know the following points:

  • Smell. Natural mushrooms have a light earthy flavor. If the product smells of vinegar, acid, rot, or has other too strong notes, it is better not to use it in cooking.
  • Appearance. A slimy, sticky surface of the cap or stem, and significant darkening are characteristic of the stage of decay.
  • Consistency. Most mushrooms should be elastic, slightly hard, without signs of mold or decomposition.
  • When buying factory products, you need to pay attention to the harvest date and expiration date. Choose packaging with the freshest contents without deformation or rupture of the container.
  • Check dried products for the presence of insects and worms.
  • Canned mushrooms with cloudy brine should be discarded.

If there is any suspicion of freshness, the product should be thrown away without regret.

Preparing wild mushrooms

Regarding mushrooms collected in the forest, there will be slightly different recommendations. They must be carefully prepared for storage. First, you need to carefully inspect the crop and discard any unknown or apparent fruits. They may be inedible or poisonous, so it is better to avoid further processing. You will also have to throw away all rotten and damaged copies. To keep mushrooms fresh for at least two days, they must be young, strong and undamaged. Such fruits must be cleared of soil, sand, pine needles, moss, blades of grass and other forest debris so that the microorganisms on them do not provoke rotting. If there are minor darkened areas (brown or black) on the mushroom, they should be removed. Dirt from the stem also needs to be cut off. Afterwards, you can start washing the harvested crop.

It is recommended to soak the mushrooms to get rid of any remaining sand and twigs. This will also help drive out worms and insects, which are directly involved in damaging the fruit and therefore shorten the shelf life. The water should be sufficiently salty (for 5 liters - approximately 100-200 grams). All mushrooms must be dipped into the resulting solution. After 6-12 hours they need to be taken out and washed again. Place on a napkin to drain. While the mushrooms are drying, they can be examined again. If darkened areas appear, they need to be cut off with a knife.

There are several ways to keep mushrooms fresh for 3 days. But the most important thing is to choose the right place.

Preparation for long-term storage

Before long-term storage, collected mushrooms:

  1. They clear away debris and sort through it. All specimens that are unknown or questionable about their edibility are thrown away. Select healthy, hard, dense plates. They clear the soil, cut off the contaminated legs, and remove the damaged parts.
  2. Rinse with running water. To get rid of insects and worms, prepare a saline solution. Pour cold water into the container, add salt (100-200 g per 5 l). Soak for a period of 20 minutes to 12 hours. Lamellar mushrooms (volnushki, chanterelles, milk mushrooms, etc.) are soaked for 6-12 hours, tubular mushrooms (boletus, boletus, boletus, etc.) - for 20-30 minutes. Mushrooms with a bitter taste (black milk mushrooms) are soaked for up to three days, periodically changing the water.
  3. Wash again and lay out on a paper towel and allow to dry. Dried mushrooms are inspected - if dark spots appear, they are cut off.

Prepared mushrooms are placed in a paper bag or enamel bowl, which is covered with a paper towel, put in a dark, cool place - a cellar or basement, or better yet, in the refrigerator - there the product will remain fresh longer.

Advice. Do not use a plastic bag as a container - the contents can quickly become moldy and begin to rot.

Selecting a location

As already mentioned, plant-based meats should be stored in a cool, dark, and not humid place. A refrigerator is ideal for these criteria. The fruits can remain fresh in it for up to several days. Without refrigeration, they will spoil in a matter of hours. In a private house, mushrooms can be temporarily sent to the cellar. It is usually dark and quite cool there.

Whatever location is chosen, it is important to comply with one condition. Mushrooms perfectly absorb foreign odors, so they should not be stored next to foods that have a pronounced aroma. These include onions, garlic and herbs.

Our white electric friend


Mushrooms in the refrigerator
There are a huge number of species of mushrooms growing on our planet, but humans eat only a small part of them. The rest either physically cannot be eaten, due to their inedibility or inedibility, or their consumption can lead to poisoning, with more or less dire consequences.

It's no secret that quiet forest hunting is no less good for the process itself, and not just the result. But when it is finally over, and mountains of freshly picked mushrooms are piled up in the kitchen, the question always arises of how to properly preserve all this collected wealth.


The refrigerator is our friend

Since those glorious times when man tamed freon gas and the first household refrigerators appeared, this wonderful unit has been an indispensable assistant for all collectors of forest gifts, helping them preserve the harvest collected with such difficulty.

There are established epidemiological standards for the shelf life of fresh, salted, thawed, boiled or canned mushrooms. They clearly state how long certain types of food can be stored in the refrigerator. For example, ordinary store-bought champignons can be stored in the refrigerator for a week if they are in regular packaging, 10 days if vacuum packaging, and 4 days if without it at all. If the champignons are in water, their shelf life is a maximum of 2 days. Once opened, a jar of canned mushrooms can be stored in the refrigerator for no more than a day.

Champignons in marinade can be stored for 3 months at room temperature, and 12 months in the refrigerator. Dried champignons can be stored for a year. Frozen, raw - 40 days, and boiled or fried - up to six months.

Air temperature

The shelf life of mushrooms depends on the ambient temperature. The colder it gets, the longer the time interval becomes.

  • At 7-10 degrees, mushrooms are stored for up to 12-17 hours.
  • From 2 to 6 degrees – 1-3 days.
  • From -2 to 2 degrees – 3-4 days.

That is, how to keep mushrooms fresh for 3 days? You need to leave them in a place where the temperature is close to zero. In the refrigerator on the lowest shelf, fruits can remain fresh for up to 7 days without loss of taste. After this, harmful substances begin to be produced. For longer storage, you should resort to drying, canning or freezing. These processing methods stop the spoilage of mushrooms for up to 2-3 years.

How to Preserve Mushrooms for Optimal Freshness?


How to store mushrooms for optimal freshness?
How long your mushrooms will stay fresh depends largely on which method you choose to store them.

There's more to it than just pulling them out of your shopping bag when you get home and throwing them in the fridge.

Depending on how much extra work you want to do, you can make your mushrooms last anywhere from a few extra days to a whole year!

How to store mushrooms so they last longer

Fried or fried, it doesn't matter. No matter how you cook mushrooms, these mushrooms are full of flavor and nutrition. When you're foraging (from the wild or from the grocery store) for your kitchen, one thing you may be wondering is how do you store mushrooms to keep them fresh? We have the answers.

Mushrooms should be stored at 40°F or below

According to the FDA, perishable foods such as mushrooms should be stored in a clean refrigerator at 40°F or 4°C. If your refrigerator has a built-in thermostat, you should check the dial or screen regularly and adjust it if necessary. On the other hand, you can use a kitchen thermometer to check the temperature.

Mushrooms are best stored in a damp cloth

There's nothing worse than taking vegetables out of the refrigerator and realizing they're old and dry. To solve this problem, store the mushrooms in their original packaging or in a porous paper bag and wrap the mushrooms in a clean, damp cloth before putting them in the refrigerator. “If you want your mushrooms to last longer and stay fresh, this method adds moisture.” They can be stored in the refrigerator for up to one week using this method.

“Storing mushrooms in plastic wrap may seem like a logical way to store them, but you need to avoid it. When a product is wrapped too tightly, it can start to sweat, which will affect its quality.”

Never freeze fresh mushrooms

Looking for a way to extend the shelf life of mushrooms? While many types of food can be frozen and cooked later, it is not recommended to freeze raw mushrooms because they will not stay fresh, but remember that fried mushrooms can be stored in the freezer for up to a month.

Selection of cookware

To store mushrooms, it is better to take a glass or metal container with enamel walls. To prevent them from drying out, they need to be covered. You cannot seal it with a lid - the product must breathe. Cotton fabric or paper is ideal. If you need to preserve fresh mushrooms for a day, you can put them in an airtight container.

Some people prefer to use craft bags. They are made of durable paper that does not get wet and at the same time allows air to pass through. Bags made of natural fabric (cotton or linen) have a similar property. They create natural aeration necessary for mushrooms. But such packaging does not protect from moisture. To improve the quality of such bags, they need to be placed in a strong saline solution for several hours. Afterwards, you need to pull them out and hang them up so that the fabric dries thoroughly. Salt will not only draw out moisture, but also protect against pests.

It is not recommended to store mushrooms in aluminum containers. It will provoke early oxidation, which will lead to spoilage of the product. In addition, even aluminum tools (spoons, scoops, tongs, etc.) should not be left in containers with mushrooms.

You should also stop using plastic bags. Due to temperature changes, condensation forms in them, which is favorable soil for the appearance of mold. If there is nothing else besides polyethylene, you will have to periodically ventilate the product to prevent moisture accumulation.

Of course, any dishes with mushrooms must be sent to a cool place.

Where to store and how much salted mushrooms after salting, how to store them in the apartment?


How long to store salted mushrooms in an apartment
Sometimes it seems that the easiest way to store mushrooms in an apartment is to roll them in jars. Pickled mushrooms are suitable for rolling; they contain a lot of vinegar, and it prevents the development of harmful bacteria, but salted ones are not immune to this. Therefore, it is better not to roll up salted mushrooms, but to use the ancient methods of our grandmothers .

Advice from experienced housewives:

  • A pan of salted mushrooms can also be stored on the loggia , but you need to remember that mushrooms at temperatures below plus 3°C lose their taste , so you need to make an insulated box and store them there.
  • Salted mushrooms need to be checked once a week to see if there is enough brine in the mushrooms, if the brine has evaporated, add cold boiled water , and if mold appears, remove it.
  • If you didn’t keep track, and a lot of mold appears in the mushrooms , you need to drain all the brine, rinse the mushrooms with cold boiled water, and add new brine (for 1 liter of water, take 10 g of salt, a few peas each of black and allspice, 1 bay leaf, a few buds of cloves and garlic cloves, dill seeds, a small horseradish root).

Useful tips

How to keep mushrooms fresh for several days? To do this, it is important to observe some nuances.

  • For short-term storage, it is better to take only whole fruits, without breaks, dents or other defects. Therefore, you need to harvest the crop as carefully as possible. You should also not cut the mushrooms into pieces.
  • You don't need to wash the mushrooms for too long. They quickly absorb water, which impairs taste and shortens shelf life. After washing, you need to dry the fruit thoroughly using napkins or a paper towel.
  • It is advisable to process plant-based meat within a few hours. If you need to postpone this task and keep the mushrooms fresh until the next day, then it is better not to wash them, but only clean them of debris and wipe them with a cloth. Afterwards you need to leave it in the cold in the recommended container.

The dangers of eating stale mushrooms

It is recommended to use mushrooms for their intended purpose immediately after collection or purchase. Stale specimens smell unpleasant, darken, wrinkle, become moldy, and become slimy. In champignons, when pressed, juice appears from under the cap; at the cut site, the flesh becomes dark, whereas it should be pink.

Eating stale, even edible, mushrooms is dangerous to health and life. In this regard, mushrooms are no different from any already spoiled products, but poisoning with them is much more dangerous, since it occurs in a severe form. When the first signs of intoxication appear, you should immediately call a doctor.

How to tell if champignons have gone bad

Mushrooms do not last long. To extend their shelf life, collected specimens are cleaned of debris and insects and sent to a cellar or refrigerator. In this case, the storage time depends on the method, type of mushrooms and temperature, degree of illumination of the room, and sometimes on the container.

Salting mushrooms

This is a very interesting way to preserve the freshness of mushrooms, which few people know about. Pour a layer of salt into the pan. Place a row of clean mushrooms on it. Alternate layers until the pan is filled to the top. The mushrooms will be tasty because they will take as much salt as needed for storage. The container can be kept in the refrigerator for up to a week.

Mushrooms in a net

This method is even more unusual; it involves hanging storage. Mainly suitable for the oyster mushroom genus. The fruits need to be cut into strips and wrapped in tight balls, the diameter of which is 10-20 centimeters. Then place them in nylon tights, stockings or mesh. Hang the resulting bags in the basement or cellar. You can store even more than one day, up to one month. Over time, such balls become even tastier and more aromatic, as they produce new mycelium.

Outdoor storage

Usually no one takes a refrigerator with them to the forest. But even there you can preserve mushrooms for several days. How to do it? To do this, the peeled fruits need to be spread out in one layer in a well-ventilated place. This will help evaporate excess water from the caps and legs. Afterwards, the mushrooms should be cut into pieces and hung over the fire, strung on a thread. They will dry out quite quickly, so you should be careful not to burn them. In this form, the harvest will be able to “survive” home.

So, if certain conditions are met, it is quite possible to prolong the freshness of mushrooms. In this case, it is not at all necessary to resort to drying or freezing.
