Several fresh-keeping techniques of Lentinus edodes
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.

Roasting and Storage of Lentinus edodes
Bag Lentinus edodes has become a pillar industry of rural economic development in many mountainous areas, but in the process of Lentinus edodes cultivation, due to untimely management, or abnormal climate and large temperature difference, it is easy to form some deformed or inferior Lentinus edodes (collectively referred to as vegetable mushrooms). If these inferior mushrooms are not treated and directly enter the market as fresh mushrooms, the price is very low and the market is not smooth. If they are roasted into dried mushrooms, they can not only appreciate in value, but also sell well. First, raw material treatment. The shearing handle of fresh mushroom should be determined according to mushroom shape, mushroom meat, mushroom quality and mushroom noodles.

Drying technology of Lentinus edodes
Lentinus edodes is not only a famous and valuable edible fungus in the world, but also a traditional export commodity in China. Lentinus edodes contains unique flavor, rich nutrition, tender and smooth meat, is one of the commonly used ingredients of Chinese and foreign famous dishes, and is known as the king of dishes.
