12 methods of keeping Edible Fungi fresh

After finishing, the fresh mushrooms harvested in cold storage are put into baskets and baskets and covered with multi-layer wet gauze or hemp bags. Put the cylinder in the shade, there is a small amount of water in the cylinder, put the wooden frame on the water, put the basket on the wooden frame, and then seal the cylinder mouth with thin film.

After dormancy and fresh-keeping, put it in the room above 25 degrees Celsius for 3 hours for 5 hours to make it breathe vigorously, then put it in a cold storage at about 0 degrees Celsius for about 12 hours, and the shelf life at about 20 degrees Celsius is about 4 degrees Celsius for 5 days.

The method of controlled atmosphere preservation is to manually control the temperature, humidity and gas composition of the environment to achieve the purpose of fresh-keeping.

Simple controlled atmosphere preservation stores fresh mushrooms such as Lentinus edodes and bisporus mushrooms in controlled atmosphere bags with oxygen content of 1%-2%, carbon dioxide 40%-nitrogen 58%-59%, and can be stored for about 8 days at 20 degrees Celsius.

"Silicon window" bag fresh-keeping silicone rubber proportionally embedded bag fresh-keeping silicone rubber embedded in the plastic bag wall to form a "silicon window" fresh-keeping bag. The plastic bag can rely on the "silicon window" to automatically adjust the ratio of oxygen to carbon dioxide in the bag. In order to achieve the purpose of safe storage of fresh mushrooms.

Radiation treatment can effectively reduce the deterioration of fresh mushrooms and get a better fresh-keeping effect.

The radiation preservation of Pleurotus ostreatus was irradiated with cobalt 60 rays with a radiation dose of 5 ~ 100000 rads and stored at 0 ℃ to keep the color, smell and texture of Pleurotus ostreatus for 7 days.

The radiation preservation of straw mushroom was treated with cobalt 60 radiation in paper-plastic bagged straw mushroom. the radiation dose was 8 ~ 120000 rads and kept fresh at 14 ~ 16 degrees Celsius for 2 days.

Chemical fresh-keeping is the use of chemicals to inhibit the respiratory intensity of fungus and prevent the activities of spoilage microorganisms.

Soak the fresh mushrooms in 0.6% salt water for about 10 minutes, drain and store them in plastic bags. At 10-25 degrees Celsius, after 4-6 hours, the fresh mushrooms turn bright white and can be kept fresh for 3-5 days.

Sodium pyrosulfite is sprayed on the mushroom body with 0.15% sodium pyrosulfite aqueous solution, which can be stored for 5 days at 15-20 degrees Celsius.

Soak fresh mushrooms in 0.001%-0.1% aqueous solution for 10 minutes and keep them fresh for 5-8 days at 5-22 degrees Celsius.
