Mushrooms are an integral element of Russian cuisine. Some varieties (oyster mushrooms, champignons) are grown as agricultural crops, others (chanterelles, honey mushrooms, boletus mushrooms) are collected in their natural habitat. On sale you can find various products in raw, dried, frozen and canned forms. In cooking, they are used to prepare hot dishes, salads, soups, snacks, and pies. Every housewife should know how long mushrooms can be stored and be able to navigate all their diversity.
In a refrigerator
Fresh
If we are talking about artificially grown varieties (champignons, oyster mushrooms) in factory packaging, then their shelf life is on average 14-21 days at a temperature of +/-2°C and a relative humidity level of 80-85%.
Other representatives of the mushroom kingdom are placed in a refrigerator for no more than 3 days. At the same time, if you do not plan to cook them right away, you should not wash, peel or cut the product. Dry plastic or glass containers are perfect for storage. There is no need to cover the container with a lid, since the air should constantly circulate freely; it is better to cover it with a napkin made of natural fabric or paper.
Some species can retain nutritional value a little longer than their counterparts. For example, freshly picked white mushrooms will last up to 5 days, young forest mushrooms - up to 7 days.
Fried
As a rule, fried mushrooms should be eaten within 3 days from the moment they are placed in the refrigerator, but this period can be extended. To do this you need:
- Prepare sterile glass jars and metal (iron, tin) or plastic lids.
- Place your supplies in containers and pour vegetable oil on top.
Oil, as a natural preservative, will preserve the product for at least a month.
Pickled
Marinade for homemade mushroom preparations usually consists of water, vinegar, citric acid, salt, sugar, and spices. During industrial production, it is possible to add artificial preservatives and flavor enhancers. As a rule, storage conditions and terms are written on the snack can. Shelf life when placed in a refrigerator is 12-24 months.
Canned
Mushroom preservation is often used as a component of complex dishes, salads and baked goods. Thanks to this method, the taste of the product remains virtually unchanged. A sealed factory jar retains nutritional value for 1-3 years.
Once opened, must be consumed within 1 day. For homemade preparations, the shelf life is similar.
You should only eat proven products, since there is a high risk of contracting botulism.
Dried
As a rule, species such as boletus, boletus, aspen, and chanterelle are dried. It is better to define the “freshness zone” of the refrigeration chamber as a place to store such products. The closed space of the refrigerator will prevent insects from entering. Vacuum bags will help protect against high levels of humidity and possible mold. Thanks to such safe packaging, the product will last in the refrigerator for up to 1.5-2 years, and no foreign odors will penetrate inside.
Boiled
Boiled mushrooms are stored at +2+4°C for 3 days. In order to increase this period, you should add salt and vegetable oil to the container with the product. Drain the water first. Thanks to such additives, boiled mushrooms will last on the refrigerator shelf for at least 1-2 months. Before use, you can re-boil it in salted water.
Rules and terms of storage of artificially grown mushrooms (oyster mushrooms and champignons)
Stores sell oyster mushrooms and champignons grown exclusively under artificial conditions. There is no doubt about their good quality, unless their expiration date has expired.
Mushrooms bought in a store also need to be sorted out and decisively rejected, even those specimens that have slight damage, since they themselves will not last long, and they will spoil the rest of the mushrooms. Rejected specimens will be fine for cooking right now, and the strongest ones can be sent for storage.
It is advisable to place fresh, dry, unwashed oyster mushrooms or champignons in a paper bag, which is placed in a vegetable container at the bottom of the refrigerator.
- How long can oyster mushrooms and champignons be stored in the refrigerator at +1...+4 degrees? In such conditions they can survive for about a week.
- If you simply pour mushrooms into the vegetable drawer of the refrigerator, they will last no more than 3-4 days.
- If you leave them in room conditions, their shelf life will be reduced to a day.
Plastic bags are less suitable for storing such mushrooms, since they stop air access to them, the mushrooms will begin to rot and deteriorate before the end of the week.
It is best to store champignons and oyster mushrooms frozen, especially boiled ones. Cooked mushrooms need to be cooled and placed in a bag or plastic container, closed with a lid and put in the freezer. You can do the same with fried mushrooms.
Do you follow the advice on the shelf life of mushrooms? Did you even know about these rules or did you reach them through experience? Tell us about it in the comments.
In the freezer
Only freshly picked mushrooms should be frozen. Before placing in the freezer, you must perform a number of manipulations:
- Clear supplies of soil and debris.
- Select the freshest representatives of the mushroom kingdom with an elastic cap, without darkening and wormholes.
- Rinse quickly and thoroughly.
- Large specimens can be cut.
- Place on a cutting board so that the mushrooms do not touch each other, and place in the freezer for 12-18 hours until completely frozen.
- Then quickly pour the preparations into pre-prepared portion bags or containers and put them back in the freezer.
If everything is done correctly, mushroom stocks will last for about two years without damage.
Re-freezing defrosted food is prohibited.
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.
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.
Recommendations
Basic recommendations to extend the shelf life of inventories:
- Initially, you should prepare the raw materials. Check for insects and worms. To do this, immerse the workpieces in a container with salt water for several hours. If there are worms inside, a saline solution will help get rid of them.
- After rinsing, dry the product by placing it on a paper towel.
- Place the dried raw materials in appropriate containers that do not impede air circulation. It is better to avoid plastic bags due to the risk of mold formation.
- There is no need to wash it before drying. Just carefully remove dirt with a cloth made from natural fabrics or a knife.
- Choose the largest and strongest specimens - they will last longer and can be cut for convenience.
- The storage place should be cool and dark (not higher than 20°C, avoid penetration of direct sunlight and temperature changes).
- Aluminum cookware is not suitable for storing supplies, as it accelerates the oxidation process.
- When freezing, label the package and note the date and time.
- Periodically sort through dried items and throw away those that are unusable.
- You should not place products with a strong odor next to the mushrooms; they can absorb it.
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.
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.
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.
Other methods
You can also dehydrate mushrooms and turn them into powder, but we don't have much experience with this. You will need to use some kind of food, dehydrate it or cook it at 125°F for 8-9 hours.
Dehydration basically dries out the mushroom with a water content of 90-95%. This slows down the rate of its deterioration. You will still need to store it in an airtight container to prolong its shelf life.
Another way to extend the shelf life of mushrooms is to use food that you put in the refrigerator. You simply place them in a food storage container. It helps regulate the flow of oxygen and carbon dioxide.
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.
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.
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.
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.
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 soak dried mushrooms for soup
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.

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.
