Why does tea taste less flavorful shortly after purchase? Upon inquiring at a tea shop, one discovers improper storage is the culprit. So, what precautions should be taken when preserving tea in daily life?
Tea must be protected from high temperatures: The optimal storage temperature for tea is between 0°C and 5°C.Excessive heat causes sugars, amino acids, vitamins, and aromatic compounds in tea leaves to break down, diminishing both quality and fragrance.
Tea should avoid sunlight: Prolonged exposure to sunlight accelerates the oxidation of pigments and esters in tea leaves, causing chlorophyll to break down into magnesium-depleted chlorophyll. Tea should not be stored in glass containers, as sunlight exposure in glass or transparent plastic bags triggers chemical reactions that degrade the quality of green tea.
Tea leaves should not be exposed to oxygen for extended periods: Chlorophyll, vitamin C, esters, aldehydes, and other compounds in tea readily react with atmospheric oxygen. Oxidized green tea leaves cause the brewed liquor to turn reddish and darken, significantly reducing its nutritional value.The ideal humidity for tea storage is around 60%. If it exceeds 70%, moisture absorption can easily lead to mold spots, acidification, and deterioration. During hot summers, tea containers should be placed in a cool, shaded area. The above outlines how to properly store tea. We hope this information is helpful and wish you a pleasant life.
