Last Updated: 2024/11/24, Mushrooms are the best to eat fresh, but because they should not be kept for a long time in the natural environment, especially when mushrooms are cultivated in a large area, they can be exported to earn foreign exchange through storage and preservation, delayed sale or canned products. This paper introduces the storage and fresh-keeping technology of several kinds of mushrooms: 1. Cold storage. After finishing, the collected fresh mushrooms are placed in containers such as baskets, plaques or baskets and covered with multi-layer wet gauze or hemp bags. Put the jar in the shade, hold a small amount of water in the jar, place a wooden frame on the water, put the baskets and baskets containing fresh mushrooms on the wooden frame, and then seal the cylinder mouth with film.

Mushrooms are the best to eat fresh, but because they should not be kept for a long time in the natural environment, especially when mushrooms are cultivated in a large area, foreign exchange can be earned through the export of products such as storage and fresh-keeping delay or canning. The storage and fresh-keeping techniques of several kinds of mushrooms are introduced here.

1. Keep fresh in cold storage. After finishing, the collected fresh mushrooms are placed in containers such as baskets, plaques or baskets and covered with multi-layer wet gauze or hemp bags. Put the jar in the shade, hold a small amount of water in the jar, place a wooden frame on the water, put the baskets and baskets containing fresh mushrooms on the wooden frame, and then seal the cylinder mouth with film.

2. Dormancy to keep fresh. The shelf life of about 20 ℃ is about 4 days.

3. Modified atmosphere fresh-keeping. The method is to achieve the purpose of keeping fresh by manually controlling the temperature, humidity and gas composition of the environment. Fresh mushrooms are stored in modified atmosphere bags with oxygen content of 12%, carbon dioxide of 40%, nitrogen of 58% and 59%, and can be stored for about 8 days at 20 ℃.

4. Silicon bag fresh-keeping. The silicone rubber is embedded in the plastic bag wall in proportion to form a silicon window fresh-keeping bag with the function of keeping fresh. This kind of plastic bag can rely on the "silicon window" to automatically adjust the ratio of oxygen to carbon dioxide in the bag, so as to achieve the purpose of fresh storage of fresh mushrooms.

5. Keep fresh in brine. Soak the fresh mushrooms in 0.6% salt water for about 10 minutes, drain and store them in plastic bags. Under the condition of 10 ℃ to 25 ℃, the fresh mushrooms turn bright white after 4 to 6 hours and can be kept fresh for 3 to 5 days.

6. Vitamin B9 fresh-keeping. Soak fresh mushrooms in 0.1% vitamin B9 aqueous solution for 10 minutes and keep them fresh for 5 to 8 days at 5 ℃ to 25 ℃.

7. Sodium pyrosulfite keeps fresh. The mushroom body was sprayed with 0.15% sodium pyrosulfite aqueous solution and stored for 5 to 8 days at 15 ℃ to 20 ℃.
