It can be put in the refrigerator for refrigeration, and it will be black and spoiled if frozen. Put shiitake mushrooms in the refrigerator to help preserve and keep them fresh.

When storing shiitake mushrooms, it is necessary to avoid storing shiitake mushrooms in strong light, and at the same time, it is necessary to avoid packaging them with light-transmitting materials;

To store shiitake mushrooms in sealable containers such as iron cans and ceramic jars, the containers should be lined with food bags. The container mouth should be opened as little as possible, and it can be stored in oxygen-filled bags if conditions permit. Shiitake mushrooms must be stored in a low-temperature ventilated place, so the container containing shiitake mushrooms can be sealed and stored in the refrigerator or freezer.

Put fresh shiitake mushrooms in the frozen storage of the refrigerator to extend the shelf life, thaw them before use, but do not freeze them repeatedly.

It is generally stored in the refrigerator for up to two days.

How to store dried shiitake mushrooms:

1. Dry storage, whether it is fresh or dried shiitake mushrooms, they have strong water absorption, and when the water in the shiitake mushrooms is high, it is easy to oxidize and mold, causing them to be difficult to store. Therefore, we have to dry the shiitake mushrooms before storing them. An appropriate amount of dry charcoal or lumpy lime and other absorbent aerosols can be placed in the storage container to absorb moisture and prevent moisture.

2. Sealed storage. Oxidation is the process of metamorphosis of shiitake mushrooms, so we need to create an environment that cuts off the oxygen supply to inhibit its oxidative deterioration. We can use sealable containers such as ceramic jars or tin cans to hold shiitake mushrooms, and the containers should be lined with food bags.

In the process of storage, the container mouth should be opened as little as possible, and the air in the food bag should be discharged when sealing.

3. Low temperature storage. Shiitake mushrooms must be stored in a ventilated and low-temperature place, preferably in a sealed container and stored in the refrigerator or freezer.

4. Store away from light. Infrared rays will heat up shiitake mushrooms, and ultraviolet rays will trigger actinics, which will speed up the deterioration of shiitake mushrooms. Therefore, it is necessary to avoid storing shiitake mushrooms in bright light, and also avoid packaging them with light-transmitting materials.

5. Store separately. Shiitake mushrooms can not only absorb water, but also have strong adsorption, easy to smell and must be stored separately, and do not use containers with odor volatilization or containers with odor to store shiitake mushrooms.

Fresh shiitake mushroom storage:

1. Fresh shiitake mushrooms can be stored for about 15 days at about 5 degrees, but usually shiitake mushrooms have been damaged during transportation, which makes the shelf life of shiitake mushrooms shorter, probably less than 10 days, so it is best not to store them in the refrigerator for more than a week, and the best eating period should be within 3 days;

2. If you find that the color of the mushroom umbrella is black (the reason for more moisture), do not put the mushrooms in the refrigerator too early, you should spread out the mushrooms and place them on the cool floor to dry for a few hours, and then put them in the refrigerator after the color of the mushroom umbrella turns gray or appears dry;

3. At any time, when you find that the mushroom umbrella turns black, you should discard it, because the blackened mushroom has deteriorated, and its smell has changed.
