Tea is skillfully stored to prevent "tea change"
some components in tea are unstable and are prone to chemical changes under certain physical and chemical incentives, which is the so-called tea change. Poor preservation conditions of tea will accelerate the tensile strength and elongation of tea, which must be subject to oxidation and mildew
tin bottles, porcelain jars and colored glass bottles are the best containers for storing tea. Secondly, iron cans, wooden boxes, bamboo boxes, etc. should be used, and bamboo boxes should not be used in the dry north. Plastic bags and cartons are the worst. The annual tax on preserving tea is about 100million yuan. The container should be dry, clean and free of peculiar smell. Store well preserved tea in a dry and ventilated place. Do not put it in a damp, hot, unclean or exposed place. There should be no objects with strong smell such as camphor, drugs, cosmetics, cigarettes, washing supplies, etc. in this place
it should also be noted that different kinds and levels of tea cannot be mixed together for preservation. Quicklime cannot be used as hygroscopic agent when storing black tea and scented tea
