Green tea packaging, tea packaging manufacturers

Life, people often buy some green tea to drink, don't drink at a time, that should be how to store? First of all, we must consider the following aspects: 1. Moisture problem: green tea is a kind of hydrophilic porous material, thus has strong moisture absorption and moisture. Storage of green tea, the relative humidity in 60% relatively appropriate, more than 70% will be due to the absorption of moisture in the mould, and acidification of metamorphism. 2. High temperature problem: green tea tea best preserved temperature of 0 to 5 ℃. Too hot tea amino acid, carbohydrate, vitamin and aromaticity of material will be destroyed by decomposition, make quality, aroma and taste are reduced. 3. Sunshine: sunshine will promote oxidation of green tea pigment and esters, chlorophyll can be decomposed into magnesium chlorophyll. Green tea tea stored in glass containers or transparent plastic bag, the sunlight, the inner material will react, make bad quality green tea. 4. Oxidation of the problem: the chlorophyll in green tea tea, aldehydes, esters, vitamin C and other easy to combine with oxygen in the air, after oxidation of green tea tea can make the green tea tea looked red, deep, the nutritional value is reduced greatly. 5. The odor problem: green tea contains palm enzyme and terpene dilute polymer compounds. This kind of material is live wave unstable, can absorb peculiar smell. Therefore, the tea with the smell of items when mixed with storage, can absorb odor and cannot be removed. Storage must satisfy the attention to the problem of more than a few points, make corresponding measures, can save good green tea. If you made a small bag of a small packet of green tea, packed in vacuum bags, it can turn away a lot of questions, consumers buy back and don't have to save the trouble.
