9 major effects Drinking green tea often has many benefits [2]

　　After understanding the efficacy and function of green tea, many netizens may not know the storage method of green tea. Let’s take a look at it with Xiaobian.

　　A bogey wet:

　　Green tea is a kind of loose and porous hydrophilic substance, so it has strong moisture absorption and moisture regain. When storing green tea, the relative humidity is 60%, and when it exceeds 70%, mildew spots will occur due to moisture absorption, and then acidification will occur.

　　Second, avoid high temperature:

　　The optimum storage temperature of green tea leaves is 0-5℃. If the temperature is too high, amino acids, sugars, vitamins and aromatic substances in tea will be decomposed and destroyed, which will reduce the quality, aroma and taste.

　　Three bogey sunshine:

　　Sunlight can promote the oxidation of green tea pigments and esters, and can decompose chlorophyll into pheophytin. Green tea leaves are stored in glass containers or transparent plastic bags. After being exposed to sunlight, their internal substances will react chemically, which will deteriorate the quality of green tea leaves.

　　Four bogey oxygen:

　　Chlorophyll, aldehydes, esters and vitamin C in green tea are easy to combine with oxygen in the air. The oxidized green tea leaves will make the green tea soup turn red and deepen, which will greatly reduce the nutritional value.

　　Five bogey odor:

　　Green tea leaves contain high molecular palm enzymes and terpenoids. This kind of substance is extremely unstable in nature and can absorb odor widely. Therefore, when tea leaves are mixed with odorous items for storage, they will absorb the odor and cannot be removed.
