Tea experts pointed out that tea easily absorbs moisture and absorbs odors. At the same time, under conditions of high temperature, high humidity, sunlight, and sufficient oxygen, it will accelerate changes in the composition of tea leaves, reduce the quality of tea leaves, and even make tea aged in a short period of time. Deterioration. To maintain the quality of tea for a long period of time, we must pay attention to moisture-proof and high-temperature protection, avoid light and oxygen, and keep away from odors. 1. Famous tea: It is the tea that is most easily aged and deteriorated in all teas, especially famous green tea and black tea. It is easily aged and loses its luster and unique aroma. Home storage of famous teas, especially famous green teas, such as Longjing tea, Dongting Biluochun tea, etc., can be used to absorb moisture storage method, that is, choose a sealed container (such as tile cylinders, tile jars or iron smell without hearing, etc.), the massive lime Placed in a cloth bag and placed in a container, the tea leaves are wrapped in kraft paper and placed on a cloth bag, and the container mouth is sealed. The container should be placed in a cool and dry environment as far as possible. The conditions can also be quicklime hygroscopic tea leaves with aluminum composite bag packaging, built-in oxygen scavenger, sealed and placed in the refrigerator, can maintain tea quality for about two years. 2. Jasmine tea: It is a reprocessed tea of ​​green tea. Its water content is higher than that of red and green tea, and it is easily degenerated. When storing, care should be taken to avoid moisture, light, and odors. Store in a cool, dry, odor-free environment. 3. Yellow tea, black tea, and oolong tea: Relative to green tea, aging is slower and easier to store. Generally can be placed in a sealed dry container, avoiding light and high temperature and different odor items, can be stored for a long time. In addition, at present, there are two types of tea products sold on the market: packaged tea and bulk tea. Because tea is a kind of easily-absorbed and odor-absorbing product that is susceptible to pollution and susceptible to environmental changes, it is difficult to preserve products; the quality and sensory quality of bulk tea cannot be guaranteed. In addition, the selling price of bulk teas is arbitrarily large, and teas of the same quality in different markets often have large differences in their prices, and the interests of consumers are vulnerable to damage. Compared with bulk tea, the advantages of packaging tea: First, it is not easy to be contaminated and not easily deteriorated. Second, the standardized product packaging has clear grades, production dates, plant names, site, production standards, etc. Once it is found that quality problems are easy to complain, to avoid the loss of consumer interests.
