[sovereignty item] 1. A fresh-keeping processing method for wild vegetables and edible fungi, which is characterized by the following process steps: (1) collection and classification: timely processing of wild vegetables and edible fungi.Harvest, Grade according to the grading standard; (2) Extract: for wild vegetables and edible fungi, roots, weeds and other parts that do not meet the quality standards should be removed; (3) Placing on the plate: place the selected wild vegetables or edible fungi on the frozen plate according to kilograms per square meter. The frozen plate is covered with polyethylene plastic film, and the wild vegetables or edible fungi are placed on the plastic film; (4) Ultra low temperature quick freezing: put the frozen plate after placing wild vegetables or edible fungi into the quick freezing box, turn on the freezer after sealing, so that the wild vegetables or edible fungi in the quick freezing box can be quickly frozen for hours at a temperature of -30 ℃ to -35 ℃, and then shut down after maintaining for hours; (5) Vacuum dehydration and drying: quickly move the quick-frozen wild vegetables or edible fungi into the vacuum dehydration and drying oven, turn on the vacuum pump after sealing, so that the vacuum degree in the vacuum dehydration and drying oven is between PA, and gradually increase the temperature, rise to ℃ within hours, and then maintain this temperature for hours, take corresponding conditioning and protective measures, so that the water content of wild vegetables or edible fungi is between 5%-15%, and shut down; (6) Sealed packaging: put the dehydrated wild vegetables or edible fungi into the packaging bag again, vacuum the package when sealing, and then put it into the carton packaging, which is the finished product

[Abstract] a process method for processing wild vegetables and edible fungi, which consists of several steps, such as harvesting, grading, picking, placing, ultra-low temperature quick freezing, vacuum dehydration and drying, sealed packaging, etc; The water content of the processed products is between 5% and 15%. When eating, use water to soak and rehydrate according to the above statement. The processing process of this method hardly destroys the nutrients of wild vegetables and edible fungi. After rehydration, it is as fresh as before, crisp, fresh and tender, light, fragrant and beautiful, rich in nutrients, achieving the purpose of active preservation. It has the characteristics of simple preparation method, good preservation effect, convenient transportation, etc. in the first half of the year, mtmarion will provide nearly 130000 tons of lithium concentrate
