core tip: in the processing of fresh-keeping mushrooms, we should first pay attention to the freshness of raw materials, which is an important factor determining the quality of finished fresh-keeping mushrooms. The raw materials must be fresh and normal in color; Secondly, the mushroom shape should be complete, round and upright, and the mushroom handle should be intact, so as to maintain the beautiful shape of the mushroom when it grows naturally; The mushroom meat is plump, the edge of the mushroom cover is rolled neatly, the mushroom membrane is not broken or slightly opened, and the umbrella is not opened; The diameter of mushroom cover shall not be less than 38 mm; No pests, peculiar smell and soil impurities

[China Packaging News] in the processing of fresh-keeping Lentinus edodes, we should first pay attention to the freshness of raw materials, which is an important factor determining the quality of finished fresh-keeping Lentinus edodes. The raw materials must be fresh and normal in color; Secondly, the mushroom shape should be complete, round and upright, and the mushroom handle should be intact, so as to maintain the beautiful shape of the mushroom when it grows naturally; The mushroom meat is plump, the edge of the mushroom cover is rolled neatly, the mushroom membrane is not broken or slightly opened, and the umbrella is not opened; The diameter of mushroom cover shall not be less than 38 mm; No pests, peculiar smell and soil impurities

raw material processing and refrigeration

raw material precooling and dehumidification in order to maintain its good freshness and color, fresh mushrooms should enter the cold storage for precooling and cooling in time after picking. According to the performance of the equipment and the moisture content of fresh mushrooms, grasp the appropriate precooling temperature and appropriate dehydration rate, and achieve the export requirements through precooling and dehumidification

generally, blast cooling is used to control the temperature of the cold storage between 1~3 ℃, and the central temperature of fresh mushrooms is 2~4 ℃, so that the water content of fresh mushrooms is reduced to 75%~80%. Under normal temperature, the method of ventilating and discharging humidity in shade or spreading in the sun is not suitable

classification and selection of raw materials according to the requirements of foreign trade customers, the classification screen made of white iron is usually used for screening or manual visual sorting according to the diameter of mushroom cover. Grading usually adopts the three-level system: the diameter of the large-scale mushroom (L) cap is more than 55 mm, and the diameter of the intermediate mushroom (m) cap is 45~5. Various experimental curves required by the standard can be selected (residual experimental force or logarithmic residual force, relaxation force or logarithmic relaxation force, relaxation rate or logarithmic relaxation rate, temperature and other relationship curves with time or logarithmic time can be drawn). 5 engineering plastics: the supplier develops new technology of high-performance plastics between mm; The diameter of small-scale mushroom (s) cap is between 38~45 mm. During the grading of raw materials, damaged, unsettled, discolored, spotted, deformed and unqualified inferior mushrooms should be removed, and they should be put into storage and refrigerated in time after selection. Where conditions permit, grading and sorting can be carried out in the cold storage to ensure the good quality of fresh mushrooms

during cold storage, the temperature of the cold storage directly affects the quality of fresh mushroom products. Therefore, the temperature of the cold storage is extremely important. If the temperature of the cold storage is higher than 5 ℃, the fresh mushrooms can still continue to metabolize, resulting in the freshness of the fresh mushrooms decreasing, the tissue aging, and finally the umbrella opening; If the cold storage temperature is lower than 0 ℃, fresh mushrooms are vulnerable to freezing damage, and the mushrooms will soften physically, and eventually they will rot and deteriorate in the form of water stains, and even cannot be eaten. Therefore, the refrigeration temperature during refrigeration must be strictly controlled between 1~3 ℃

packaging and transportation

the packaging of fresh mushrooms is different from that of other products. In order to ensure the quality of fresh mushrooms, the packaging materials and containers must be hygienic and non-toxic. In addition, they should also be heat-insulating and airtight, not affected by the external environment, have strong cold insulation performance within a certain period of time, and can keep fresh mushrooms in a good low temperature state

the packaging container of fresh-keeping Lentinus edodes is a rectangular plastic box with a cover made of foam plastic, and there are ridges around the cover, which closely coincide with the mouth of the box. After loading the mushrooms, stick and seal the sides of the box mouth with transparent tape. The specification of the foam plastic box is: inner length is 45 cm, inner width is 28 cm, inner height is 16 cm, and the thickness of the box is about 2 cm

fresh mushroom packaging must be carried out in a clean and hygienic low-temperature room with no odor and temperature not higher than 3 ℃. Packaging utensils and staff uniforms should be kept clean and disinfected regularly. Non staff are not allowed to enter or leave the packaging place at will to prevent the rise of storage temperature and the contamination of products with germs and sundries

packaging must be carried out before the export date is determined. First, cut the fresh mushroom handle short, leaving a length of about 2.5 cm, and package it while cutting the handle. If you cut the mushroom handle too early, the cut mouth of the mushroom handle will be oxidized and browning, affecting the appearance. Fresh mushrooms are packed in plastic film bags. Each bag is filled with 5000 grams of mushrooms of the same level. After vacuuming, it is loaded into a foam plastic box. The box mouth is bonded and sealed and covered with a double corrugated box, and the box mouth is added with adhesive paper tape

small packages are usually made of small trays made of foam plastic bags. Each tray is filled with 100g or 200g fresh mushrooms, arranged neatly, with some bacterial folds facing outward, wrapped with a layer of fresh-keeping film on the outside, sealed airtight or vacuumed, and then loaded into cartons with sticky paper tape at the mouth. After packing, mark it and wait for shipment

fresh mushrooms should be shipped in time after packaging. Fresh mushrooms exported from the origin to the port must be transported by refrigerated trucks, and the refrigeration temperature must be strictly controlled to prevent the temperature from rising, so as to ensure the quality of fresh mushrooms

several problems that should be paid attention to in production

most of the fresh-keeping Lentinus edodes belong to artificially cultivated sawdust Lentinus edodes rather than log cultivated Lentinus edodes. In order to inhibit the harm of miscellaneous bacteria in production, carbendazim or other fungicides are usually mixed into the nutrient of cultivated Lentinus edodes for mold prevention and sterilization, and the dosage should be strictly limited to the minimum safe range for human body in the atmosphere exposure

during the cultivation and production of Lentinus edodes, a large amount of water must be sprayed every day. The water must be clean and free from microorganisms and metal substances harmful to human body, so as to ensure the cleanness and hygiene of fresh mushrooms

like other mushrooms, Lentinus edodes contain a lot of water, generally more than 90%. In order to maintain the quality of finished products and shorten the time of dehumidification, it is strictly forbidden to spray water the day before picking fresh mushrooms

in the fresh-keeping process of Lentinus edodes, it is necessary to effectively control three levels, namely, the quality of raw materials, pre cooling and moisture removal, and low-temperature refrigeration. Carefully control the temperature and moisture content of finished products

when shipping fresh-keeping mushrooms for export, ordinary vehicles must not be used to replace refrigerated trucks for transportation, so as to avoid temperature rise and deterioration of fresh product quality
