A bogey humid: green tea is a porous hydrophilic material, it also has a strong influx of moisture. Green tea store, the relative humidity in the 60 percent would be more appropriate, more than 70 per cent will occur because of moisture absorption and Meiban, further acidification metamorphism.
The high temperature bogey: green tea best storage temperature for 0-5 ℃. The high temperature in tea amino acids, carbohydrates, vitamins and aromatic substances will be broken down damage to the quality, aroma, taste has also been reduced.
3 bogey sunshine: Sunshine will promote green tea pigment material and ester oxidation, can become decomposition of chlorophyll from magnesium chlorophyll. Green tea stored in glass containers or transparent plastic bag, irradiated by sunlight, its intrinsic material will be a chemical reaction, so that green tea quality deterioration.
4 bogey oxygen: green tea in chlorophyll, aldehydes, esters, vitamin C, and easy integration of oxygen in the air, the green tea of green tea will turn red liquor color, variable depth, the nutritional value greatly reduced.
Wuji smell: green tea in the Palm polymer containing enzymes and dilute terpene compounds. Live wave of such substances naturally extremely unstable, and is widely suction smell. Therefore, the smell of tea and a mix of items stored release, but will be unable to absorb odour removal.
