Introduction of Long-term Storage and Fresh-keeping Methods and Temperature Requirements of Mushroom Cold Storage

There are many types of mushrooms, with high nutritional value and high, but they are not easy to store. Mushrooms can be stored for three to five days at room temperature for up to three to five days, after which they will appear discoloration, taste, deformation, weightlessness, deterioration and infection caused by microorganisms. Rotting phenomenon.

Using the cold storage storage method will not be restricted by natural conditions, can effectively inhibit the enzyme activity in the organism, kill various pathogenic microorganisms, and at the same time can avoid the loss of moisture and nutrients of the mushrooms, thereby prolonging the purpose of preservation and storage.

Below, the editor will give you a detailed introduction to the storage method and storage temperature requirements of the mushroom cold storage.

Mushroom cold storage storage method and temperature requirements:

1. Harvesting requirements

In order to better store and keep fresh mushrooms, the mushrooms should be harvested in the morning or evening on a sunny day. The purpose of this is to reduce the breathing intensity of the mushrooms, which is conducive to the long-term storage of the mushrooms in the fresh-keeping cold storage. Avoid harvesting in strong sunlight. After harvesting, it must be transported to a cool place to spread out to avoid moisture loss due to exposure.

2. Screening and sorting

After the mushrooms are harvested, they are graded according to their quality. At the same time, the mushroom feet are cleaned and the mushrooms that are damaged by diseases and insects and mechanical injuries are removed.

3. Pre-cooling requirements

Pre-cooling is a necessary step before mushroom storage. The main purpose of pre-cooling is to reduce the respiratory intensity of mushrooms. Because mushrooms have a strong respiration effect after picking, if they are not pre-cooled, conditions such as umbrella opening, browning, taste change, and quality deterioration will occur. It is recommended that the pre-cooling temperature be controlled at 3-4°C.

4. Storage temperature

The most suitable storage temperature for mushroom cold storage is 0-2°C. It should be noted that the temperature in the storage is stable, and neither too high nor too low will work. In addition, humidity is also an important factor that affects the moisture of mushrooms and maintains quality and flavor. Therefore, the relative humidity of the mushroom cold storage should be controlled at 90%-95%. If the humidity in the storage is insufficient, ordinary air humidifiers or microwave air humidifiers can be used. Humidify to keep the humidity in the warehouse stable.

Using this method, mushrooms can be stored for about 12 to 15 days. Since there are many types of mushrooms, different varieties have different storability. According to different types of mushrooms, the temperature requirements and humidity requirements of the cold storage are also different. For details, please consult our engineers.
