Detailed Explanation of Key Technical Points for Picking and Processing Famous Autumn Tea
(1) Tea leaf picking. Pick lightly and handle lightly. For tea bushes with good growth and a thick layer of green leaves, you may leave fish leaves or pick without leaving leaves. For those with poor growth and a thin layer of green leaves, especially tea bushes that suffered severe early drought, with many fallen leaves and exposed bare branches, the main approach should be to retain and nurture them, and in the later stage adopt the method of tipping and picking while leaving leaves. This allows the tree vigor to recover quickly and benefits a bumper spring tea harvest the following year. (2) Fresh leaf storage. In early autumn, temperatures are high and the climate is dry; fresh leaves have lower moisture content than spring tea. During transport and storage, it is necessary to prevent too-rapid moisture loss and excessive dehydration of fresh leaves. The containers holding fresh leaves must be well

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

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

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,

Processing Methods and Technical Key Points of Longnan Biyu Tea
Longnan Biyu Tea is produced in the Longnan tea region at the junction of Gansu, Shaanxi and Sichuan in southern Gansu. The production area has a mild and humid climate; on clear days, fog covers the ground in the morning and evening, while on rainy days, clouds fill the mountains all day long, providing unique growing conditions for tea trees at high latitude and high altitude. Longnan Biyu Tea uses tender buds and leaves of medium- and small-leaf population tea trees picked during the period from Qingming to Guyu as raw materials, and is processed through fixing, carding, drying, refining and other processes. Its appearance is flat, straight, slender, with a jade-green, even and lustrous color, a fresh, high and elegant aroma, a mellow, refreshing and crisp taste, and a tender, even, green and bright infused leaf. 2003

A detailed explanation of the processing flow of Xizi Liren tea, explained in one article
Xizi Liren tea is produced in the area of the eastern slope of Dongbai Mountain in the southeast and the Longmen Mountain range in the western mountainous area of Zhuji City, the hometown of Xishi. The main peak of Dongbai Mountain, Taibai Peak, and the main peak of Longmen Mountain, Sanjie Peak, both have elevations higher than 1000 m. Here, mountains surround the area, peaks rise one after another, appearing and disappearing in undulation, with lush trees, year-round shrouding clouds and mist, and ever-flowing clear waters. The entire climate environment forms the high-mountain wonder of "fog everywhere in the morning and evening on clear days, clouds all over the mountain on rainy days." Tea trees grow for a long time under diffused light and are nourished by rain and dew, so the buds and leaves are plump and tender and rich in internal substances, which lays a good material foundation for the unique quality of Xizi Liren tea.

What are the requirements for Pu'er tea processing? These points are key
Pu'er tea refers to loose tea and compressed tea made from large-leaf sun-dried green tea (mao cha) produced within Yunnan Province as raw material, processed through traditional techniques or post-fermentation. Farmer processing refers to tea farmers picking or purchasing fresh leaves themselves, fixing them in iron woks or crucibles, rolling the leaves into strips, and sun-drying them to make sun-dried green tea (mao cha), which is then further processed. 1. Raw material requirements 1. Raw material procurement. The raw material purchased for Pu'er tea must be large-leaf sun-dried green tea (mao cha) that complies with GB9676 "Hygienic Standard for Tea". 2. Raw material transportation. The packaging containers and transport vehicles for holding raw materials shall meet hygiene requirements, and must not be transported together with toxic or harmful substances. Fresh leaves shall be held in clean, well-ventilated bamboo-woven or mesh tea baskets or crates; bags previously used for feed, chemical fertilizer, or pesticides must not be used to hold fresh leaves. The picked tea leaves shall be transported to the tea factory promptly to prevent deterioration of the fresh leaves and contamination by toxic or harmful substances. 3. Raw material storage. The raw material warehouse must be ventilated, dry, and clean, with a level floor, good drainage, and rodent-proof facilities; it shall have dedicated personnel for management, and a management system shall be established.

What are the processing methods for goji berries? A detailed explanation
The harvested fruit is usually sun-dried or oven-dried. ① Sun-drying: Spread the fresh fruit on a bamboo mat or bamboo sieve to a thickness of 2-3 cm. During the first two days of drying, it should not be exposed to strong direct sunlight; dry it in the sun before 10 a.m. and after 3 p.m., and at noon place it in a sunny, well-ventilated spot to air-dry. By the third day, it can be placed in the sun to dry completely. Do not turn it with your hands while drying; generally dry for 8-10 days. ② Oven-drying: Spread the fresh fruit in a bamboo mat or bamboo sieve and place it in a drying room.
