Environmental conditions for storage of tea five points

Environmental conditions for storage of tea five points

Causes a qualitative change in the tea has been referred to moisture, temperature, oxygen, light and other factors will affect the integrated effect of the tea quality changes, so from the processed tea, to drink in front of the store, should be strictly controlled environmental conditions specific requirements are as follows:

1, the Treasury's basic requirements. Tea warehouse to moisture, light, heat and pollution, no peculiar smell around the Treasury, the terrain Gaozao, facilitate drainage, ventilation and cooling convenience, but also closed shading, bank temperature does not exceed 30 degrees, relative humidity controlled at 20 degrees to The following should be used for special purposes, shall not be mixed other goods.

2, insulation requirements. High-temperature oxidation will accelerate the tea contains substances to promote tea, "aging" to speed up. So during the summer heat, to keep the temperature does not exceed the warehouse 30 ℃, and can also use both heat sealed containers for the storage of tea, in such an environment storage of tea, you can avoid the high temperature on the quality of impact.

3, dark demands. Light rays, make tea in the chlorophyll and other chemical components, causing discoloration, and a "sun" ingredients, reduce the quality of tea. Even at low temperatures and anaerobic conditions, fresh tea leaves, in the event of strong light, still make tea color deterioration. Therefore, requests from the processed tea to drink before going dark.

4, moisture requirements. First of all, the tea water content storage requirements, to comply with storage standards required from a scientific point of view should be at 3% moisture content of tea to keep tea does not degenerate. More than 6% it is easy to "aging", it should control the water content of tea stored below 6%. Secondly, in rainy weather, high humidity outside the Treasury, the high temperature case shall purchase the goods, the Treasury's doors and windows should be shielded so that storage to maintain a cool, dry environment.

5, anti-pollution requirements. Because tea contains more palmitic acid and the structure with pores, and therefore have a strong adsorption. It is easy to absorb the odor around the tea. Kept in storage when it is necessary to pay special attention to, not with other commodities, particularly odorous goods store together, but can not use flavored tea packaging materials, packaging and unsanitary delivery vehicles tea. Tea storage, tea processing, tea shops should avoid odorous toxic gas processing, storage, management.
