Can you still drink green tea that has been left out for more than ten years? Will it affect the tas

Green tea that has been stored for ten years, it is better not to drink it anymore, because it has long passed green teaShelf lifeGreen tea that has passed its expiration date will definitely affect the taste of drinking.

Everything has an expiration date, and once it has expired, using it again may have an effect on the body. The shelf life of green tea is usually 18 months to 24 months, and some green teas may have a longer shelf life. Green tea has been stored for more than ten years, even if the green tea has been kept in a low temperature place, in a dark place, the green tea has passed its expiration date, and after the expiration date, do not drink it again.

It may be that the green tea bought back then was very high-end and very expensive, but because it was stored for more than ten years, the shelf life of green tea has long passed. Green tea may spoil, and even if the green tea does not go bad, the taste of the tea will also be affected when brewing. The nutrients in green tea will also be greatly reduced, or even completely gone.

Brewing green tea that has expired may have an impact on the body. Tasting tea is the taste of tea, and tasting is also a mood, so don't drink expired green tea.

The taste of green tea in those years is the best, and many people like to drink fresh green tea. Fresh green tea is rich in nutrients and is good for the human body. Green tea has been stored for ten years, it has passed its expiration date, and even if it does not have mildew, it is not fresh, so do not drink green tea that has been stored for ten years.

Anyone who has ever tasted tea knows that fresh green tea has a very fragrant flavor when brewed, while old tea has no special aroma when brewed. If you are reluctant to throw green tea, you can soak the green tea in water, and then dry the green tea, and you can use the green tea to fill the tea pillow, which can play a role in awakening the brain and strengthening the brain. It can also be boiled with green teaTea eggs.

Tea is still liked by many people in life, and for young friends, they still prefer to drink green tea. You should know that the shelf life of tea is generally about 12 months, if it is well preserved, then the shelf life will be slightly longer, so if you place more than 10 bottles of green tea, try not to drink it, otherwise it is likely to cause some harm to the body. <>

As we all know, most of the tea on the market is sealed and preserved, at this time, if you have not opened the tea bag, or have been putting the tea in the freezer for preservation, then it can be stored for several years. Although the storage time will be very long, the longer the time, the nutrients in the tea will disappear, and even some toxic components will be produced. Therefore, take out the tea leaves, put them in the sun to observe, if there is mold or smell, do not drink it, throw it away immediately, such tea has deteriorated, if you drink it again, it is easy to cause harm to yourself.

In addition, many people have a wrong idea that the longer the tea is preserved, the higher the nutritional value will be, which is not unreasonable. Like Pu'er and white tea, the price of these teas will be higher precisely because the longer they have passed. However, at this time, drinking green tea that has been left for 10 years will become particularly indifferent and tasteless, and it will also lose the original taste of green tea.

Therefore, it is recommended that everyone drink fresh green tea, and the shelf life of tea is at most one year, and if it is more than one year, try not to drink it. <>

Although many people think that the ** of green tea is very expensive, and they are reluctant to throw it away, but such tea is placed, it has no effect, and in the process of brewing, it will be mixed with some other impurities. You must know that fresh green tea will have some fragrance, which is refreshing to drink, so you can also judge the time and quality of green tea according to the fragrance, and when you are fine, you can drink green tea appropriately, which will feel particularly comfortable.

I don't think you can drink green tea that has been stored for 10 years, because under normal circumstances, green tea cannot be kept for 10 years, and even if it is preserved for 10 years, it cannot be drunk again; 10-year-old green tea not only tastes very bad, but also has many potential dangers to the body.

It is best not to drink green tea that has been placed for ten years, green tea generally only drinks new tea, and the achievement tea that has been left for a long time will not taste very good. Moreover, if green tea is stored for too long, it will cause microorganisms to be bad for the body.

If you can't drink it, it's likely to have deteriorated, and it will definitely affect the taste, so it's best not to drink it lightly.

There is no value anymore, because the green tea that has been left for twenty years has expired and cannot be drunk.

Green tea is different from other raw teas, green tea is mainly drunk fresh, so the shelf life is shorter, generally only 6 to 18 months. And if green tea can be stored under sealed, canned, and frozen conditions, this can increase the shelf life of green tea without affecting the nutritional value of green tea. But once the green tea is opened, it must be drunk as soon as possible, otherwise the green tea is more likely to deteriorate due to moisture and lose its drinking value, so if it is green tea that has been left for 20 years, don't drink it!

Precautions for the preservation of green tea.

1. Avoid moisture.

Green tea tea is a loose and porous hydrophilic substance, so it has strong moisture absorption and moisture resistance. When storing green tea, the relative humidity is more suitable at 60%, and more than 70% will cause mildew due to moisture absorption, and then acidify and deteriorate.

2. Avoid high temperatures.

The best storage temperature for green tea leaves is 0 5. If the temperature is too high, the amino acids, sugars, vitamins and aromatic substances in the tea will be decomposed and destroyed, so that the quality, aroma and taste will be reduced.

3. Avoid sunlight.

Sunlight will promote the oxidation of green tea leaf pigments and esters, and can decompose chlorophyll into demagnesium chlorophyll. Green tea leaves are stored in glass containers or transparent plastic bags, and after being exposed to sunlight, their internal substances will have a chemical reaction, which will deteriorate the quality of green tea leaves.

I recently drank Tieguanyin, which has been sitting for twenty years. After cold brewing, it feels good for internal heat. I didn't notice anything unusual about my body.

No matter what kind of tea you have, you can't drink it for a long time! Because after a long time, mold can grow, and the tea has also deteriorated, and drinking it is not good for the body!

If the tea is intact, fresh and without discoloration and odor, you can continue to drink, otherwise do not drink, so as not to be harmful to health.

Can you still drink moldy green tea.

Definitely can't drink it.

If green tea becomes moldy due to moisture or other reasons, its internal nutrients will not only be contaminated by mold, but also produce corresponding mycotoxins, so that the taste and nutritional value of green tea are greatly reduced, and there may be health hazards, so it cannot be continued to drink.

What happens if the tea leaves are moldy and drunk.

A small amount of edible moldy tea leaves soaked in water may be fine, or abdominal pain may occur.

Diarrhea, vomiting and other physical symptoms, but if you drink more moldy tea for a long time or at one time, it will cause greater damage to the liver and other organs, and can induce major diseases.

The difference between tea and mold.

Taste difference. Many people say that from the appearance, the fine fluff on the tea is as difficult to distinguish as moldy tea, which is not to worry at all, if you can't tell whether the tea is moldy or not in appearance, then get close to the tea and smell it to see if there is a musty smell, generally moldy food will have a heavier musty smell, which is obviously different from the tea fragrance of the tea itself.

How long can you not drink the leaves.

Usually, the shelf life of tea leaves in sealed packaging ranges from 12 months to 24 months, which will be indicated on the packaging bag of the tea. The shelf life of bulk tea is shorter, and when buying, try to choose the new tea of the year to buy.

At the same time, it depends on the degree of tea fermentation, Pu'er tea is a fully fermented tea, of course, the longer it is put the better, Tieguanyin is a semi-fermented tea, so the shelf life can not be stored like Pu'er tea, if you want to put it for a long time before drinking, it is recommended that you put the sealed tea leaves in the refrigerator freezer. This allows it to be stored for a longer period of time. It also does not affect the taste.

The shelf life of tea is related to the variety of tea, and the shelf life of different tea leaves is also different. Like Pu'er tea, black tea, etc., are fully fermented products, and the shelf life can reach 10 to 20 years. Therefore, the state does not set a shelf life for it.

In general, it is better to be fresh. Like green tea, the shelf life is generally about one year at room temperature. However, the main factors that affect the quality of tea are temperature, light, and humidity.

If stored properly, these factors are reduced or eliminated, and the tea leaves can last for a long time. To judge whether the tea is expired, there are mainly the following aspects: to see whether it is moldy or old; Whether the green tea turns red, and the soup color turns brown and dark; The concentration, astringency and freshness of the taste decrease, in addition to the shelf life on its packaging, and if it is a loose tea, it is best not to drink it for more than 18 months.

Usually, the shelf life of tea leaves in sealed packages varies from 12 months to 24 months. The shelf life of bulk tea is shorter, because the process of placing it outside in bulk will absorb moisture and odor, which not only makes the tea lose its original tea flavor, but also makes it easier to deteriorate. For example, green tea is generally better to be fresh.

The shelf life is generally about one year at room temperature.
