Natural fermentation method of dark green tea

Abstract

The invention relates to a natural fermentation method of dark green tea. The method includes: packaging dark green tea into a sealed paper bag, putting the paper bag containing the dark green tea to a permeable box, taking the paper bag out of the box during storage of the dark green tea, and putting the paper bag back into the box after the paper bag is subjected to air permeability, wherein the air permeates the box, enters the paper bag and is in contact with the dark green tea, and the dark green tea absorbs heat, water and oxygen in the outside air to perform natural fermentation. The method adopts natural ageing is suitable for large-scale industrial production, prevents contamination in logistics transportation processes, controls the starting time for fermentation, avoids secondary packaging of the tea, reduces the cost and prevents secondary pollution. The method allows full play of collection and investment value of the dark green tea, promotes development of the tea industry, promotes energy conservation and environment protection and benefits the nation and the people.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for natural fermentation of black tea. Background technique [0002] Existing post-fermented teas such as Pu'er tea, Liubao tea, Anhua black tea, etc., all achieve a special taste and taste through artificial fermentation or natural fermentation of tea leaves. Artificial fermentation is to carry out composting fermentation by controlling temperature, humidity and time in specific cellars or workshops or large mechanical devices. Natural fermentation is to let the tea leaves be stored in a natural environment, allowing them to absorb heat, water, and oxygen in the air and carry out slow fermentation. [0003] Pu'er tea, Liubao tea, Anhua dark tea and other dark teas are usually packaged in bamboo baskets, bamboo shells, plus sacks, cloth bags or cartons. After arriving at the sales terminal, it will be unpacked and packaged. There are various types of unpacking...

AI Technical Summary

Problems solved by technology

During the logistics and transportation process, the above-mentioned tea will be mixed with other goods and will be polluted by vehicle exhaust.

After disassembly and packaging, iron boxes, tin cans, ceramic cans, wooden boxes, and bamboo boxes have good airtightness, which is not conducive to the natural aging of tea, and the cost is high; the cost of bamboo baskets and rattan baskets is relatively low, but the materials are easy to deteriorate, which is not conducive to Long-term storage will have a negative impact on the quality of tea
