Storage and fresh-keeping methods of edible fungi

Edible fungus is a very popular food in China, and there are many kinds of edible fungi. And no matter what kind of edible fungus we need to do a good job of storage. Storage can maintain the excellent species of edible fungi and prolong the service life of edible fungi. Therefore, the storage and preservation of edible fungi is very important, so the editor brings you the storage and preservation methods of edible fungi today. Let's make a brief introduction to the editor. Let's have a look.

1. Low temperature storage at bottom hole

Low temperature storage at bottom hole is the most commonly used method for storing edible fungi in China. It is an alternative method for friends who have their own wells. First of all, we should seal the mother species of test-tube edible fungi that need to be used for storage and apply appropriate amount of paraffin wax with sterilized aseptic rubber plugs. Then tie it tightly in a closed jar or watertight plastic bag. Then put it to the bottom of the well for storage, under normal circumstances, it can be stored for 3-4 months.

2. Paraffin sealed storage

Paraffin sealing storage is also a commonly used storage method of edible fungi. First of all, we need to cut the sterile wax paper into a square of about 7 centimeters, and then soak it in alcohol for about a minute. Then put the mouth of the test tube that needs to be stored on top of the alcohol lamp for rotary sterilization. Then take out the wax paper and fasten the mouth of the pipe tightly. Then put the mouth of the tube into the melted paraffin and wrap it tightly in wax paper to avoid air leakage. After the paraffin has cooled, store it in the refrigerator.

3. Cellophane seal storage

Cellophane sealing storage first needs to prepare the sealing agent, with gelatin, copper sulfate, methylene blue and other items into hot water to dissolve and mix together. Then pull out the cotton plug of the test tube full of mother seed, face down, and seal it with sealing agent. Then put the cellophane in and soak it, then stick it to the mouth of the tube and dissolve it with paraffin wax. At room temperature, this storage method can last at least 8 months, and can avoid the pollution of pathogens and pests.

4. Barnyard manure storage

Barnyard manure storage is very suitable for the storage of straw rot fungi such as Pleurotus ostreatus. First of all, the rotten cow dung should be dried and broken, then sifted with a sieve, add an appropriate amount of water to adjust the humidity, put it into the test tube, and keep the depth at about half. Then carry on the sterilization work to ensure the inoculation after asepsis. When the mycelium is full and stored in the environment of about three degrees, the storage time is very long, and its production characters will not change greatly.

The above is a brief introduction to the storage and preservation methods of edible fungi. That's all for today's introduction. This article is for reference only. I hope it can help you all.
