We can say with certainty that air leakage of the tea aluminium pouch has no impact at all, because the impact on the quality of tea mainly includes the following aspects.
1.Influence of temperature on the quality of tea: temperature has a great influence on the aroma, soup color and taste of tea. Especially in July August in the south, the temperature can sometimes be as high as 40 ℃. That is, tea has been stored in a dry and dark place, and will deteriorate quickly, making green tea not green, black tea not fresh, and flower tea not fragrant. Therefore, in order to maintain and extend the shelf life of tea, low-temperature insulation should be used, and it is best to control the temperature between 0 ° C and 5 ° C.
2.Influence of oxygen on tea quality: the air in the natural environment contains 21% oxygen. If tea is stored directly in the natural environment without any protection, it will be oxidized quickly, making the soup red or even brown, and the tea will lose its freshness.
3.The influence of light on the quality of tea. Light can change some chemical components in tea. If the tea leaves are put in the sun for a day, the color and taste of the tea leaves will change significantly, and thus their original flavor and freshness will be lost. Therefore, tea must be stored behind closed doors.
4.Effect of moisture on tea quality. When the water content of tea exceeds 6%. The change of each component began to accelerate. Therefore, the environment for storing tea must be dry.
If the vacuum aluminum laminated foil pouch leaks, as long as the foil mylar bags is not damaged, it only means that the package is not in a vacuum state, but it does not mean that tea will directly contact the above four aspects, so it has no impact on the quality of tea and can be safely drunk. Tea is to be drunk when you buy it, so we suggest that you open the bag first for the leaky package. Tea packaged in vacuum bags without air leakage can be stored in a cool and normal temperature, with a shelf life of up to 2 years.
