What are the technical key points of scientific processing methods for shiitake mushrooms?
1. Sun-drying method: Sun-drying is the most convenient and easy method. The method is: spread the harvested shiitake mushrooms promptly on a sun-facing grain-drying yard or concrete ground. When drying, first place the caps upward and the stems downward, arranging them one by one. After drying until half-dry, turn the stems upward and the caps downward, until they are more than 90% dry. If rainy weather occurs, supplement with fire-powered drying. 2. Oven-drying method: After the shiitake mushrooms are harvested, they should be placed in small baskets, not packed too full to avoid crushing, and should be baked on the same day. The general method is: spread the harvested shiitake mushrooms on drying trays

A Detailed Guide to Harvesting and Processing Shiitake Mushrooms
Storage and processing content: Harvesting methods for shiitake mushrooms (1) Harvesting time. It is best to harvest mushrooms on a sunny day, because mushrooms harvested on a sunny day have less moisture and better color; mushrooms harvested on a rainy day have more moisture, are difficult to dry, and are prone to turning black during the baking process, making it difficult to guarantee processing quality. For shiitake mushrooms cultivated indoors with bagged substrate, it is best not to spray water directly on the mushroom logs (blocks) before harvesting. (2) Harvesting method. In winter, temperatures are low, shiitake mushrooms grow slowly, and the harvested mushrooms have thick flesh, a strong aroma, and good quality. In autumn and spring, because temperatures are higher,

Detailed Explanation of the Processing Method for Canned Shepherd's Purse and Shiitake Mushrooms
→ Filling cans → Hot water exhaust → Sealing → Sterilization → Cooling → Incubation inspection → Labeling → Packing → Finished product II. Key Operation Points (I) Pre-boiling After the shepherd's purse is sorted and washed, it is placed in boiling water and boiled for 4-6 minutes; 0.2% sodium sulfite is added to the pre-boiling water to preserve color. (II) Soaking Soak the shiitake mushrooms in water After removing the stems, place them in 30-40°C water to soak; the water can be changed several times during soaking. (III) Shredding After soaking, the shiitake mushrooms are washed and cut into shreds 2-3 mm wide. (IV) Filling cans Shep

Detailed Explanation of Canned Surimi Processing Technology
Canned surimi processing was developed on the basis of surimi product processing. Products such as boiled fish balls, fried fish balls, and seasoned surimi can all be processed into canned foods. These canned products have the unique flavor of surimi products. Here, seasoned eel surimi canned product is taken as an example. (1) Process flow: raw material handling, mincing, grinding and kneading (with seasonings added) -> filling into cans -> pre-sealing -> vacuum sealing -> sterilization -> cooling. (2) Operating points: 1. Raw materials: select iced fresh or frozen eel with good freshness; deteriorated fish must not be used. 2

Detailed Explanation of the Processing Technology of Ready-to-Eat Pickled Pepper Plumfish
Plumfish, also known as plum croaker, belongs to the family Sciaenidae and the genus Sciaena. It is an important species in China's marine fishing, with a large yield and a low price. Therefore, plumfish is generally used together with other low-value fish as a raw material for surimi processing. 1. Auxiliary materials: red chili peppers, Sichuan peppercorns, old ginger, garlic, refined salt, pepper powder, star anise, cinnamon, white granulated sugar, peanut oil, etc. 2. Processing flow: cleaning → descaling, gill removal, gutting → cleaning → soaking → seasoning → precooking → cleaning and cooling

Detailed Explanation of Key Points on Licorice Harvesting and Processing Technology
Harvesting and Processing Licorice is generally harvested after 1-4 years of cultivation. In Hebei and Beijing, it is harvested after 1-2 years of cultivation; in Inner Mongolia; Northeast China, and **, it is harvested after 3-4 years of cultivation. There are currently 2 cultivation methods: one is direct seeding, and the other is raising seedlings in the first year and transplanting in the second year. When transplanting, plant them flat and lay them horizontally in the field to facilitate harvesting. The first method is simpler and requires less labor; the second method is suitable for small-area household planting with intensive cultivation. For large-area planting, harvesting is a problem, and manual digging is very difficult. After many years of testing, a 55-type Iron Ox rubber-tired tractor can be used, with a plowing depth of about 45 cm, plowing one row at a time, and then manually using a four-tooth rake to pick out the licorice roots plowed out, then plowing the second row. One tractor paired with 10 workers can generally harvest about 10 mu per day, and the root damage rate is also somewhat lower than manual digging. The residual roots lost in the field are about below 10%, meeting the requirements, opening a new path for large-area licorice planting. After the harvested licorice roots are dried in the sun for a few days, use manual shears or a guillotine to cut off the rhizome heads and tails, and cut out licorice strips for cutting into oblique slices for export. The rhizome heads, fibrous roots, and tails are tied into bundles and used as hairy licorice for extracting licorice paste. For licorice grown for two years, the general dry weight of licorice strips is about 250-300 kg per mu, and hairy licorice is about 300 kg per mu. The output value per mu can reach about 4000 yuan.

Processing Methods and Key Technical Points for Shiitake Mushrooms After Harvest
After harvesting shiitake mushrooms, processing must be organized promptly, striving to pick and dry them the same day to prevent blackening, deterioration, and rotting. Processing and drying methods: 1. Sun-drying. Sun-drying is the most convenient and easiest method for drying shiitake mushrooms, and sun-dried mushrooms have a higher vitamin D content. The method is: spread the harvested shiitake mushrooms promptly on a sunlit grain-drying yard or cement ground. When drying, first place the caps facing up and the stems facing down, arranging them one by one. After drying until half-dry, turn the stems facing up and the caps facing down, until they are more than ninety percent dry. If

Detailed Explanation of Processing Methods for Plain Whole Scorpion and Salted Whole Scorpion
Plain whole scorpion is also called clear-water scorpion. Before processing, soak the collected whole scorpions in clean water for about 1 hour, stirring gently at the same time, to wash off mud, sand and dirt from the whole scorpions and to make the whole scorpions excrete feces. After removing them, put them into boiling water and cook over high heat for about 30 minutes; the water in the pot should preferably cover the whole scorpions. After taking them out of the pot, spread them on a bamboo mat or put them in a basin to air-dry (sun-drying is also acceptable). It should be noted that the cooking time for whole scorpions should not be too long, so as to avoid destroying the effective medicinal components of the scorpion body. Salted whole scorpion is also called brine scorpion. The processing method for salted whole scorpion is to first put the scorpions into
