How to properly store mushrooms: fresh frozen and after heat treatment

How mushrooms store nutrients

Mushrooms contain a lot of protein, about 1% fat, close to 3% carbohydrates, amino acids and vitamins. Also microelements (copper, zinc, iron, cobalt, calcium and potassium). Due to this content of useful substances, mushrooms are considered a dietary product, but we still must not forget that mushrooms are difficult to digest by the body, and you cannot eat a lot of them.

White mushrooms

There are mushrooms that have a healing effect on the body :

  • Porcini mushrooms destroy E. coli.
  • Russula: greenish (scaly), brownish, blue-green, olive suppress the growth of malignant tumors.
  • Chanterelles and russula suppress staphylococci.

Russula greenish (scaly)

Various edible mushrooms are useful for headaches, gout, and chanterelles improve liver condition .

Many useful substances in mushrooms are preserved if they are processed immediately after collection and marinated or salted.

But most of the nutritional properties are preserved in mushrooms if they are frozen .

Here is an unusual way to freeze mushrooms :

  1. We clean edible (do not take conditionally edible) mushrooms, rinse them in cold water, cut large ones into quarters, small ones - whole.
  2. Prepare a lemon solution (1 teaspoon of lemon juice or 1.5 teaspoons of citric acid, 0.5 liters of water), and soak the mushrooms in it for 5 minutes so that they do not darken and remain a beautiful natural color.
  3. Steam the mushrooms: whole medium-sized mushrooms – 5 minutes, small ones or cut into quarters – 3-5 minutes, finely chopped – 3 minutes.
  4. Distribute the cooled mushrooms into bags and freeze in the freezer.

What mushrooms can be stored in the freezer?

Forest mushrooms grown independently on the site and purchased are suitable for freezing.

According to their structure they are divided into:

  • tubular (boletus, boletus, porcini mushroom, etc.);
  • lamellar (milk milk, russula, volushka, honey mushrooms, etc.);
  • marsupials (morel, truffle, stitch).

Marsupials must be boiled before freezing. It is advisable to boil lamellar ones too. Tubular ones are frozen raw. They have a porous cap that absorbs a lot of moisture when boiled, so after defrosting they become watery.

Reference. For long-term storage, it is better to dry the porcini mushroom - this way it will retain its full aroma.

Mushrooms with a bitter taste (conditionally edible) - saffron milk caps, milk mushrooms, chanterelles, russula, strings, volnushki and morels - are boiled before freezing. After heat treatment in salt water, the bitterness and toxic substances leave them.

Fresh mushrooms are frozen. Overgrown, large and damaged by insects cannot be frozen. They may accumulate toxic substances that are harmful to health.

Signs of a stale product:

  • no fresh mushroom smell;
  • slime;
  • dark spots on the cap;
  • the cap is dry, cracked;
  • the lower part of the cap of lamellar mushrooms has darkened;
