Tea is a dry goods, very easy moisture absorption and moisture produced qualitative change, it is very strong in water, odor adsorption, and aroma is very volatile. When the tea preservation is not at that time, in the water, temperature and humidity, light, oxygen and other factors, will cause adverse biochemical reactions and microbial activities, resulting in tea quality changes, so storage, with what containers, with what method, there is a certain demand. Therefore, the tea pot is born.
Because of the price and production process factors, the market is widely used in the majority of iron tea cans, because of its exquisite printing, fashionable, popular popular. From the texture of the distinction, the tea cans are generally tin, iron, ceramics, glass, paper, and so on, including the selection of double covered iron color tea cans and long neck tin bottles for the good, with ceramic storage tea, then the mouth alvine big is appropriate.
It is best to have a seal and a plastic bag for the food, the material is thicker, the density is high, do not use the flavor or the plastic bag. After the tea bag into the air should be as far as possible extrusion, such as the second plastic bag with a reverse sleeve on the better, in order to transparent plastic bag tea should not shine sunlight. The principle of aluminum foil bagged tea is similar to that of plastic bag. In addition, will buy back the tea bag packaging, sealed after the installation in the refrigerator, and then in batches of brewing, to reduce the tea after the opening of the air contact with the opportunity to delay the production of quality deterioration.
Dry storage, tea moisture absorption, high moisture content is easy to oxidize metamorphism, but also mildew deterioration. Therefore, the tea must be dry (water content under 6%) after storage, the storage container must be put into a proper amount of lime or dry charcoal, such as moisture absorbent, in case damp. (The volume ratio of lime to tea is 1:3, that is, 1/3 of lime or charcoal in the container, and 2/3 of the place where tea is placed.)
