Detailed explanation of black tea processing technology, master the key process steps
Black tea is divided into two types: domestic sales and export sales. Before 1966, all export black tea in Zhejiang was processed as Congou black tea. From 1967, it was converted to Yuehong leaf tea, and the second national set of Congou black tea naturally produced broken pieces and dust tea (that is, rolled broken black tea). For domestic black tea, product specification standards have been implemented since 1971. Black tea refining and processing selects Zhejiang rough red as raw material. The refining and processing flow is: raw material blending, grading and issuing for processing, adopting the method of two-stage issuing and single-stage (main grade) recovery, taking material from five routes: itself, long body, round body, light body,

Two Processing Methods for Dehydrated Garlic Slices and Sweet-and-Sour Pickled Garlic
1. Dehydrated garlic slices: Select fresh garlic bulbs that are well matured, free of injuries, pests and diseases, white in color and large in size. After removing the stems, separating the cloves and peeling, slice them while wet, then rinse in an aqueous citric acid solution to reduce the activity of garlic enzymes. Note that rinsing must be completed within 24 hours after slicing, so as to prevent the garlic slices from producing colored pigments due to oxidation, which would affect the color of the finished product. Place the rinsed garlic slices in a temperature-controlled dehydrator and dry them in three stages: keep the temperature at around 60°C in the early stage, increase it moderately in the middle stage, and keep it above 70°C in the late stage, but it must not exceed 78°C, so as to prevent the garlic slices from scorching, which would affect flavor and color. When the moisture content of the garlic slices drops to about 5%, the finished product is obtained.

Production Method and Food Processing Technology of Green Beans in Tomato Sauce
Production Method 1. Material selection: Grade the green beans into large and small sizes using a grader, and remove moldy, insect-damaged, dry-scarred, mottled, and off-colored beans. 2. Soaking: Soak in clean water for 16-24 hours (water-to-bean ratio of 2:1), changing the water to prevent sprouting and spoilage. The soaking time depends on air temperature, judged by thorough saturation. 3. Pre-cooking: Treat with 0.05% sodium hydroxide solution (solution-to-bean ratio of 1.5-2:1) at 99-100°C for 20-30 minutes (judged by

Key Technical Points and Detailed Process for Processing Seedless Candied Jujubes
(1) Ingredients: 50 kg dried red jujubes, 30 kg soft white sugar, 100 g citric acid. (2) Operating points: 1. Select milky-white stage jujubes that are large, have small pits, thick flesh, and thin skin, and sort them into 3 grades - large, medium, and small - for processing separately. 2. Sharpen one end of a 6-8 mm diameter iron tube, pierce it in from one end of the jujube, and when pulling it out, bring the jujube pit out with it. With continuous operation, the pits are then constantly pushed out from the other end of the iron tube. 3. Soak the pitted jujubes in clean water for 12 hours, until all the wrinkles have expanded. 4. Put 25 kg water into a pot

A Detailed Guide to Scorpion Venom Collection and Processing Methods
I. Scorpion Venom Collection When a scorpion is provoked, out of its instinct for defense or attack, it will release venom from its venom sac. Scorpion venom collection is carried out based on this principle. The commonly used methods for collecting scorpion venom include the tail-cutting method, the artificial stimulation method, and the electrical stimulation method. (1) Tail-cutting method: With one hand, use tweezers to grip both sides of the fifth segment of the scorpion's posterior abdomen; with the other hand, use scissors to cut off the scorpion's tail segment. After crushing it, immerse it in physiological saline to extract the toxic portion. Collect the toxic liquid, place it in a container, and then make it into dried venom powder.

Detailed Explanation of 8 Edible Mushroom Food Processing Technologies
Fresh edible mushrooms have a high moisture content and cannot be stored for long after harvest; they soon open their caps, deteriorate, and become moldy, reducing or even losing their commercial value. At present, most edible mushrooms are sold fresh or as dried products, with very few deep-processed products, such as canned goods, which account for only 4%. In the future, people's requirements for the quality and varieties of edible mushrooms will become increasingly higher. Carrying out deep processing of edible mushrooms and developing a series of products is currently the main way to broaden the production field and sales market. 1. Mushroom preserves 1. Raw material selection: Select fresh mushrooms with medium-sized caps, natural color, intact mushroom shape, and no disease or insect spots as
