Oyster mushrooms: useful properties and recipes for cooking

Oyster mushrooms are a type of mushroom that has been controversial for centuries. Many mushroom growers try to avoid them, claiming that they are harmful to humans because they grow on rotten or diseased trees. Others are convinced that such mushrooms are useful for the presence of nutrients and are not inferior to other varieties.

How and where do oyster mushrooms grow?

All species of Pleurotus (except one) grow on trees, which is why they get their name. Mostly they can be found on birch, aspen, willow and pine trees.

These mushrooms grow in large groups, which often results in several heads on a single fruit body. A single group can weigh as much as 1-3 kilograms. Oyster mushroom comes in several species, most of them are edible, but there are also poisonous spore representatives.

Mushrooms are a very specific product. Despite the enormous benefits for the body, there are diseases in which the use of oyster mushrooms is strictly prohibited:

  1. All pathologies of the gastrointestinal tract. The high content of mushroom fiber, which is not absorbed by the human body, slows down the digestive system, which leads to increased production of gastric juice. Subsequently, this leads to ulcers.
  2. Kidney failure. Oyster mushroom retains fluid in the body and slows the kidneys. Introducing it into the diet in large quantities will aggravate an already existing problem.
  3. Allergies. All kinds of mushrooms are in 1st place among the products that provoke poisoning. Because of the large number of trace elements in the composition, the probability of allergic reactions increases. It is possible that the body can reject just 1 element, leading to a serious problem.

Can you be poisoned by oyster mushrooms

Wild varieties of oyster mushrooms can be dangerous to health. Some of the most poisonous include oak and coated ones. They are similar to the edible varieties, but it is strictly forbidden to consume them.

Can poisoning by oyster mushrooms

The most common mistake after eating mushrooms is to confuse the symptoms of poisoning and the usual indigestion, in which first aid immediately brings relief. Intoxication brings more problems because the harmful toxins, once in the blood, quickly spread throughout the internal organs. And only after neutralization with potent medications do the symptoms go away.

The main causes of poisoning include the following:

  • Substrates containing pesticides have been used in artificial conditions;
  • the timing and temperature of cultivation of the product were not observed;
  • wild mushrooms were picked near a road or industrial area;
  • the oyster mushroom was confused with a poisonous representative;
  • storage conditions were not met;
  • unsanitary conditions of production (when using purchased canned oyster mushrooms).

To avoid intoxication, it is necessary to carefully inspect the entire surface of the mushroom cap. The purchase or collection should be abandoned if it is found on it:

  • mold;
  • dark spots;
  • slime;
  • suspicious odor.

Symptoms of poisoning
Not knowing the reaction to mushroom products, it is better to refuse to eat them on an empty stomach. Dangerous symptoms manifest themselves as follows:

  • abdominal and intestinal pain;
  • dizziness;
  • nausea;
  • fever;
  • chills;
  • fever;
  • painful diarrhea;
  • pain in the joints and muscles.

Before the ambulance arrives, you should flush the stomach and drink green tea or water with lemon and honey. They will help reduce the effects of toxins and relieve stomach pain.

How to choose and store oyster mushrooms

  1. Buying mushrooms in the store, you should give preference to specimens of small size. Large weight and size is an indicator of age, such mushrooms become stiff and lose flavor. Cap and stem should be uniformly gray in color, without dark spots and patches.
  2. The same applies to collecting in nature. There is one more nuance: to distinguish an old mushroom from a young one, you need to break the cap and look at the break line. If it is juicy and white - the mushroom can safely be put in the basket.
  3. Also, the oyster mushrooms should only have an inherent mushroom smell. In the presence of any other flavor, they should be discarded.

Storage is acceptable in the refrigerator in a glass or plastic container with a tightly closed lid. Shelf life should not exceed 5 days.

Can I freeze

Freezing berries, vegetables and fruits helps hostesses all year round. If there are no questions to such a way of storing mushrooms, then with oyster mushrooms there are problems. And all this is due to ignorance of the rules for preparing mushrooms for freezing.

It is important to carefully inspect each mushroom. If yellow spots begin to appear under the cap, then they should be put aside and cooked immediately. This process indicates that the product has begun to deteriorate due to improper storage or moisture. Such oyster mushrooms should not be frozen.

Algorithm of action:

  1. Clean. Carefully, without causing mechanical damage, rid the mushrooms of excessive dirt. This is important for storage as a whole.
  2. Soaking and washing are not recommended because the mushrooms have a porous structure and quickly absorb liquid, retaining it for a long time. If frozen, the liquid will destroy all the useful properties of oyster mushrooms, as well as spoil the taste by adding bitterness.
  3. Arrange the mushrooms (whole or sliced) in clean, odorless plastic containers. It is important that the lid closes tightly. Then the odors of other foods and air will not enter the container.

In this form, the mushrooms can be used for cooking at any time of year.

Can I dry

Oyster mushrooms are the species with the least amount of moisture. That is why they, although not often used for drying, but they are suitable for it better than other representatives. In this form, they store well, take up little space and do not lose any of their useful qualities.

To dry oyster mushrooms, you need to perform the following steps:

  1. Peel and chop the mushrooms (optional).
  2. Wipe with a clean, dry cloth.
  3. Put them on a paper and leave in the sun for a few hours. If drying at home, it is better to do it over a gas stove or a radiator, having previously threaded the mushrooms.
  4. Elasticity is the main sign that the drying should be completed. It is important not to miss this point, as under-dried specimens can quickly become covered with mold, and over-dried - crumbling and unsuitable for further storage.
