Tea as a drink is already a part of Chinese culture, the tea bought back will generally be drunk for a long time, and there are also tea as gifts, then it may be placed for a longer time, if you find that the packaging of the tea at home has passed the expiration date, is it still drinkable?
Tea has an expiration date. The shelf life of different types of tea varies, usually around 1-2 years. The shelf life of tea is affected by the storage conditions, such as the temperature, humidity, light, and odor of the storage environment. Under good storage conditions, the shelf life of tea can be appropriately extended.
Tea is not recommended to be consumed after expiration
Because the following changes may occur to expired tea leaves:
1.Deterioration of tea quality: After the expiration of tea, its intrinsic quality will gradually decline, such as weakened aroma and lighter taste, and the drinking experience will be greatly reduced.
2.Reduced nutritional value: Tea contains a variety of vitamins and trace elements, and these nutrients will gradually decrease after expiration, and the nutritional value will be reduced.
3.Safety hazards: After the tea leaves expire, harmful microorganisms such as mold may grow, and drinking expired tea may have adverse effects on health.
The expiration of tea can check the production date of the package and the shelf life time, once the package is opened, or it is to buy bulk tea, the factors that affect its shelf life are as follows:
1.Types of tea: The shelf life of different types of tea is different, such as green tea, black tea, white tea, yellow tea, dark tea, etc., and their production processes and fermentation degrees are different, resulting in different shelf life.
2.Storage Environment: The storage environment of tea has a great impact on its shelf life. The ideal storage environment should be cool, dry, ventilated, and odorless. High temperature, high humidity, light and odor will all accelerate the oxidation and aging process of tea.
3.Packaging: The way tea is packaged will also affect its shelf life. Tea leaves in sealed packages are more insulated from air and moisture than loose tea leaves, which is beneficial for extending shelf life. Therefore, when buying tea, you should choose a product with a sealed package.
4.Tea quality: The quality of the tea itself will also affect its shelf life. Good quality tea has a relatively long shelf life;Whereas, the tea leaves of lower quality have a shorter shelf life.
5.Moisture content of tea: The moisture content of tea has a great impact on its shelf life. Tea leaves with high moisture content are prone to mold and spoilage, so you should try to keep the tea as dry as possible.
Therefore, for the shelf life of tea, the production date and shelf life of the packaged bag shall prevail, and the bulk tea shall be subject to the factors that affect the shelf life of the tea.
