The storage and preservation of tea is an important indicator to determine the taste and quality of tea.

Reduce the air humidity of tea leaves

The quality changes of tea leaves are mostly caused by a series of chemical changes, of which moisture is the key medium

Lower the storage temperature of tea

In order to explore the influence of environmental humidity and temperature on the storage quality of tea, the Tea Research Institute of the Chinese Academy of Agricultural Sciences stored the tea in six humidity zones.

Strict oxygen isolation measures

Many main components of tea are easily oxidized under the action of oxygen, especially vitamin C and tea polyphenols, which will lead to poor taste of tea, affect the nutritional value to a certain extent, and also lead to the occurrence of deterioration problems

Storage environment protected from light

Light exposure will also have a certain impact on the storage and preservation of tea leaves

separate storage environment

Tea is a porous tissue structure, generally exists in a relatively loose state, and contains palmitic acid, dilute terpenes and other substances, so it has the characteristics of sucking other odors.
