In the chain of edible fungus industrialization, the preservation and processing of edible fungi is an important organizational link, which is an indispensable link in production, circulation, and consumption. It is also the basis for the expansion of reproduction and increase of profits for the industrialization of edible fungi. . Traditional fresh mushroom sales generally use bamboo or plastic turnover boxes as containers. The harvested fresh mushrooms enter the market directly after entering the box. Sub-entities in the box are backlogged, collided, etc., making the quality of their products greatly reduced, and they are directly exposed. In the sun or in the atmosphere, it is not only passively accepted pollution but also unfavorable for preservation. Consumers are also unable to buy fresh water spirit mushrooms. This is one of them. Second, with the development of economy and the acceleration of people's living rhythm, a considerable number of consumers do not have the time or the mood to buy mushrooms in crowded farmers' markets, but they hope to have convenient, clean, small-packaged products. You can cook, so supermarket sales came into being. It is understood that supermarkets in major cities in the South have been selling small packages of fresh mushrooms for several years. The market has achieved good results. At present, supermarkets in the north have also taken actions. This shows that this is a development trend. The basic procedure is: fresh mushroom harvest → low-temperature finishing → cooling packaging → packing and transportation → entering the supermarket. Once harvested, fresh mushrooms must be neatly discharged into small, short-sized containers and sent to the low-temperature workshop as soon as possible. Container volume is length, width, height = (402,816) centimeters. It is shaped like a turnover box, a solid plate at the bottom, and a round hole with a preset diameter of about 2 to 3 centimeters around. There are retracted corner blocks at the bottom four corners to facilitate the code. High multilayer. When the fresh mushroom is harvested, it should be discharged in a straight line, so as not to cause head-to-tail contact, so as to avoid pollution; the temperature in the low-temperature workshop is 1- 3°C, and the ordinary constant temperature cold storage can be used after being transformed, together with Other packaging containers are stored in the workshop. In order to completely cool down. The fresh mushrooms are boxed and placed separately after being moved into the workshop. They must not be stacked high in order to allow the mushrooms to fully cool. This is especially important for fresh mushrooms harvested at temperatures above 15°C. The finishing tools are: thin stainless steel knife or bamboo knife, and small package sealing, boxing and other equipment. First cut the base of the fresh mushroom with a knife to remove all dirt, base materials and other debris. Scales should be removed for a long time. Generally, no water washing is used, otherwise the product shelf life will be shortened. Immediately after grading the clean fresh mushrooms, they are discharged into a foam-lined container, which is then fully cooled and packaged. Cooling packaging: When the internal temperature of the mushroom body cools below 3 °C, it can be packed. Generally, it can be used as a box with a foamy texture. It is made into a single box about 5 centimeters high. Each box contains about 150 grams of fresh mushrooms. Some big cities have banned plastic packaging and can customize paper boxes. Can also be based on fresh mushroom varieties to determine the specifications of the box, such as Coprinus comatus generally suitable (length and width, the same below) 16 cm 10 cm 4 cm specifications of the packaging, Agaricus blazei is suitable for 1510 6 specifications, Shiji mushrooms, poplar mushrooms Others are suitable for 1684 specifications. According to the shape and size of the fresh mushroom, determine the discharge method. Then wrap the cling film. Put the small packaging box into the foam fresh-keeping box again. Each box can hold 36 boxes. Packing and transport: According to the transportation distance and transportation tools, etc., the fresh-keeping box can be directly transported, and can also be shipped into a container. Because the insulation effect of the fresh-keeping box is excellent, the box-type packaging in the box is subjected to low-temperature treatment. Therefore, in the 5-12 hours, the quality of the mushrooms will not be degraded due to warming. Among them, Coprinus comatus and straw mushrooms will be the most difficult to preserve, but there will be no quality problems within 5 hours. Entering the supermarket: After entering the supermarket, the small package should be placed in the low-temperature display cabinet for sale. General shelf life up to 2-10 days. In addition, short-term storage and transportation can also be used ice fast cooling or refrigerated truck transportation and other methods, general mushroom control refrigerated temperature 1- 3 °C, after long-distance transport, the mushroom body to maintain the original color and shape unchanged, the effect better.
