Can you still drink expired tea leaves without spoilage

If it's expired, it's best not to drink it. Because the tea leaves expire, they will slowly moisten and produce a lot of mold, and the ingredients in it will change, and the nutritional value will be lost.

If the expired tea leaves are brewed and soaked in water, after the temperature drops, bacteria will corrode the soaked tea leaves and produce microorganisms, which pose a threat to human health. Therefore, it is best not to drink expired tea.

The shelf life of the tea leaves.

Tea has a shelf life, but it is related to the variety of tea, and the shelf life of different varieties of tea is not the same. The main factors that affect the quality of tea are light, temperature and humidity. If stored correctly, these factors can be eliminated or reduced, so that the tea can be shelf-stable for a long time.

But ordinary tea is still fresh. Green tea, for example, is stored at a normal temperature and generally has a shelf life of one year. For example, the tea leaves of Wuyiyan have been stored for a long time, but they have a sweet taste and a strong aroma.

There is also Pu'er tea from Yunnan, the brick tea of ethnic minorities, which has a shelf life of ten to twenty years. Many varieties of tea, as long as they are stored correctly, not only will not spoil and expire, but can even improve the quality of tea.

How to tell the shelf life of tea.

2: Fertilizer. Soaking expired tea leaves and pouring them into plant pots can promote plant growth and is a simple and cost-effective fertilizer.

3: Make a pillow or sachet. If you have too much expired tea leaves, you can use tea leaves to make pillows, and if there are relatively few of them, you can make them into sachets and smell the fragrance of tea everywhere.

Probably something like this, just for reference.

Tea can still be drunk after expiration.

Tea has a long history in China and is known as the "national drink". Every household has more or less saved some tea, there are guests to come, make a cup of tea, when there is a happy event, tea to respect the elders is also indispensable.

The shelf life of tea can be understood as the "best tasting period". That is to say, beyond this period, it does not mean that the tea will immediately deteriorate and cannot be drunk, but the natural aroma of the tea will slowly dissipate, the taste will also deteriorate, and the texture of all aspects from flavor to nutrients will be greatly reduced.

The core factor affecting the shelf life of tea depends on the tea making process, whether there is a long-term high temperature (>100) enzyme inactivation, and the degree of enzyme elimination.

Completely killing enzymes, just like green tea fried at high temperature, without the catalytic promotion of enzymes, the sugars and other substances in the tea can no longer be transformed and lose their activity. So take advantage of the freshness, and the sooner you finish it, the better.

Shelf life of common teas:

Green tea Among the six major tea categories in China, green tea is the most consumed tea. It can be stored for 18 months, i.e. a year and a half, under normal storage conditions.

The shelf life of black tea is 3 years, but in terms of taste, it is recommended to drink it within 2 years.

Black tea is a fully fermented type of tea, which is different from post-fermented tea like Pu'er. The so-called full fermentation is to carry out the fermentation process in the process of tea production, and after the processing and production is completed, the fermentation link will basically end, and there will be no natural aging and fermentation in the later stage, so there is no such thing as waiting for the new tea to be aged before drinking.

Oolong tea with a low degree of fermentation is relatively close to green tea, such as the fragrant Tieguanyin, Frozen Oolong, etc. This type of tea has strict storage conditions and needs to be refrigerated at low temperatures, with a shelf life of 18 months.

It is best not to drink the tea after it expires. After the tea expires, the chlorophyll and tea polyphenols contained in the tea combine with it, due to long-term exposure to air or poor drying, the tea will turn yellow and red, and drinking it at this time is harmful to the body.

Tea may cause the taste and aroma of tea to weaken after expiration, so it is best to drink tea within the expiration date, and once you find that the tea has passed the expiration date, it is best to throw it away in time.

Tea is after a variety of processing, dry and obtained, if expired, the tea will slowly moisten, some mold breeds in it, the tea soaked in water due to the temperature drop, bacteria will corrode the soaked tea, but the taste will be greatly reduced, most of the taste and aroma of the tea have dissipated, there is no original taste. Expired tea leaves can be used as plant fertilizer if they are not moldy.

Therefore, for the sake of good health, try not to drink some expired tea and do not use expired products, which will cause great harm to the body. If you want to drink tea, it is better to choose fresh tea.
