Several fresh-keeping techniques of Lentinus edodes

Last Updated: 2024/11/05, The respiratory intensity of Lentinus edodes is high, and it is easy to lose water in the high temperature and dry environment, which leads to the shrinkage of the mushroom body: if the environmental humidity is high, it is easy to rot. The fresh-keeping treatment methods of fresh Lentinus edodes are introduced as follows: 1. Keep it fresh at low temperature. When the fruiting body is 6-minute ripe, stop spraying for 1 day and harvest in the next morning or morning. Pinch the bottom of the fruiting body during harvest and twist it gently. You should avoid pulling the fungal handle to break it or detach the handle cover, or bring down the base material. After harvest, arrange the fresh mushrooms in a single layer in the workplace and light the stove.

The respiratory intensity of Lentinus edodes is high, and it is easy to lose water in the high temperature and dry environment, which leads to the shrinkage of the mushroom body: if the environmental humidity is high, it is easy to rot. The fresh-keeping treatment methods of fresh Lentinus edodes are introduced as follows:

1. Keep it fresh at low temperature. When the fruiting body is 6-minute ripe, stop spraying for 1 day and harvest in the next morning or morning. Pinch the bottom of the fruiting body during harvest and twist it gently. You should avoid pulling the fungal handle to break it or detach the handle cover, or bring down the base material. After harvest, the fresh mushrooms are arranged in a single layer in the workplace, and the furnace is heated to drain the surface moisture of the mushroom body. When the mushroom body loses water by about 15%, at this time, the moisture content of fresh mushroom is about 75%, and if it needs to be treated by shearing handle, it should be carried out at this time. Then Lentinus edodes was transported to the packaging workshop of 2 / 3 ℃ for pre-cooling. When the internal temperature of the mushroom body dropped to 2 / 3 ℃, the fruiting body was moved into the packaging workshop for hierarchical packaging. This fresh-keeping method can generally store Lentinus edodes for about 15 days. If you encounter a high temperature of more than 10 ℃ after the Spring Festival, Lentinus edodes can be dried outside the greenhouse during the day and will not be harvested at night for about 3 consecutive days, which can also achieve the purpose of water loss and fresh-keeping.

two。 Nitrogen filled to keep fresh. Cut the handle of the harvested fresh mushrooms according to the market requirements, or only remove the base, so as not to pollute the mushroom body with base materials or other sundries. Then put the fresh mushrooms into a nylon plastic bag (vacuum bag), rinse into 80% nitrogen, seal the package, and then move it to 2: 3 ℃ cold storage for pre-cooling.

3. Irradiation preservation: fresh mushrooms were packed in paper boxes and treated with cobalt 60 at a dose of 1000 Gore (unit of radiation dose), then transferred to 2-3 ℃ cold storage for pre-cooling.
