What season do you have mushrooms? When will it be picked? What should I pay attention to?

Mushrooms are composed of mycelium and fruiting body, which are vegetative organs and fruiting bodies. Do you know what season it has? When is it picked? Is there anything you should pay attention to in picking? According to Uncle Li of Dali, Yunnan, under natural conditions, spring February and March is the time to pick mushrooms, and there is no mushroom growth when it is too cold or too hot.

When will the mushrooms be picked?

The best time to pick mushrooms in the day is in the morning, which not only contains a lot of water and tastes good, but also has a short exposure to the sun, and there are not as many old mushrooms as they do.

What should I pay attention to when picking mushrooms?

When picking mushrooms, you should pay attention to whether they are poisonous:

1. Look at the growth zone. Edible non-toxic mushrooms often grow in clean grass or pine or oak trees, while poisonous mushrooms often grow in dark, damp and dirty areas.

2. Look at the color. Poisonous mushroom mushroom noodles are bright in color, such as red, green, ink black, cyan purple and so on, especially purple ones are often highly toxic and are easy to change color after picking.

3. Look at the shape. The non-toxic cover is flat, the umbrella surface is smooth, there is no wheel on the surface, there is no hypophore in the lower part, the center of the toxic cover is convex, the shape is strange, the surface is thick and hard, there is a wheel on the rod, the fungal strut is slender or thick, and it is easy to break.

4. Look at the secretion. The picked fresh wild mushroom tear off strain, the non-toxic secretion is as clear as water (some white), the bacterial surface does not change color; the toxic secretion is thick, reddish brown, easy to change color in the air after being torn.

5. Smell. Non-toxic mushrooms have a special smell, poisonous mushrooms have a strange smell, such as spicy, sour, fishy and so on.

6. it's a test. When picking wild mushrooms, you can use onions to wipe on the mushroom lid. If the onions become bluish brown, they are proved to be poisonous, otherwise they are non-toxic.

7. It's a cooking test. When cooking wild mushrooms, put a few pieces of rushes, a little garlic or rice with cooking, mushrooms cooked, rushes turn turquoise or purplish green is poisonous, yellowing is non-toxic; garlic or rice is poisonous without discoloration and keeping true color is non-toxic.

8. Chemical identification. Take the suspicious mushrooms collected or bought, take out the juice, soak it with paper, and immediately add a drop of dilute hydrochloric acid or white vinegar to it. If the paper turns red or blue, it will be toxic. ) (do not pick wild mushrooms by the roadside, do not eat at random ~)

Attached: storage method of mushroom

1. Controlled atmosphere storage

The main results are as follows: (1) the mushrooms are packed in a 0.04 Murray 0.06 mm thick polyethylene bag by spontaneous air control, and the low oxygen and high carbon dioxide environment is created by breathing the mushrooms themselves. The packing bag should not be too large. Generally, it is appropriate to hold a capacity of 2 Murray 4 jin, and the quality will remain unchanged for 5 days under 0 ℃.

(2) filled with carbon dioxide, the mushrooms were packed in a polyethylene bag 0.04murmur0.06mm thick, filled with nitrogen and carbon dioxide, and kept at 2muri 4% and 5murmur10% respectively, which could inhibit umbrella opening and browning at 0 ℃.

(3) the mushrooms were packed in a polyethylene bag with a thickness of 0.06 ℃ and 0.08 mm thick, and the oxygen content was reduced by vacuum, which could be kept for 7 days at 0 min.

two。 Ice storage method

Add ice to cool the mushroom body during transportation, put a layer of plastic film in the packaging container, put 4mur6cm thick crushed ice at the bottom, place an ice bag in the middle, place mushrooms around it, fold the surrounding film inward when it is 80% full, cover the film with crushed ice about 5cm thick, and finally cover the transportation.

3. Cylinder storage method

Put 4cm cold water at the bottom of the washed cylinder, set up a wooden frame and code the mushrooms on it, then seal it with plastic film and store it at a low temperature.

4. Drug treatment

(1) salt water. After harvest, mushrooms are washed with 0.6% cold salt water and soaked for 10 minutes, which can precool and prevent browning and drain water for storage. If washed with salt water, then rinsed with 0.1% ascorbic acid or 0.1% citric acid and stored, the effect is better. Drain and refrigerate in a plastic bag.

(2) sodium pyrosulfite. After harvest, wash the sundries with 0.02% sodium pyrosulfite, then put it in 0.05% sodium pyrosulfite for half an hour, rinse with clean water, drain and store, which has a good color protection effect.

5. Irradiation

Gamma ray irradiation can prevent discoloration of fresh mushrooms, inhibit respiration and parachute opening, with a dose of 200 Mel 300 rad.
