Can tea be kept in the refrigerator, and why should the tea be put in the refrigerator

But it also depends on what kind of tea it is, like Da Hong Pao and Pu'er can't be put in the refrigerator, so Tieguanyin must be put in the refrigerator. Tea leaves are refrigerated or frozen in the refrigerator than stored at room temperature, and their freshness effect is much better, but it must be noted that the tea must be sealed with a food-grade packaging bag with good air tightness, which can prevent cross-smell and moisture. It is best to refrigerate in small packets, and take out one sachet after drinking to avoid repeated access from the refrigerator.

Do not rush to open the bag of tea just taken out of the refrigerator, and wait for it to return to room temperature before opening the bag, so as to avoid the water vapor in the air condensing on the cold tea leaves and getting damp and deteriorating.

Hello! Do not put hot food or water directly into the refrigerator, this is not good for the refrigerator, it is recommended to cool down and put it in the refrigerator! The main reasons:

1 The inside of the refrigerator should be maintained at about 4 degrees so that the food stored in the refrigerator can last for a long time. When you put something hot in the fridge, the temperature in the fridge will rise. Then you have not met the condition that "the inside of the refrigerator should be maintained at about 4 degrees", which will make the food stored in the refrigerator easy to spoil.

2 When you put hot things in the refrigerator, it will bring some heat into the refrigerator, and the refrigerator needs to work twice as hard to bring the temperature down, which consumes electricity and also increases the burden on the refrigerator. 3 For even though hot food is put in the refrigerator, the surface temperature of the food decreases, but the temperature inside changes more slowly, and harmful substances can grow. 4 Hot food will increase the temperature around you, and the refrigerator has to operate at high power and will produce moisture, which will freeze on the cold plate and freeze.

In addition, the food will also absorb the odor in the refrigerator when it is cold and shrinking.

Unopened tea leaves can be stored in the refrigerator; It is best not to keep the tea leaves in the refrigerator after opening.

The sealed tea can be placed in the refrigerator and taste better.

Of course, you can't let ...... goBut if you're not afraid of stomach upset (you can try it......But I haven't tried it, I'm afraid I'm ......

No, it should be kept in a dry place.

Storing tea leaves in the refrigerator can keep them in a low temperature environment and maintain the freshness of the tea leaves. Because once the tea is stored at room temperature, it will cause oxidation of many substances in the tea leaves, and it is very suitable to store it in the refrigerator. However, it is worth noting that the dryness of the tea leaves should be ensured when putting them in the refrigerator.

When storing tea leaves in the refrigerator, the temperature should be just right, generally 0 to 6 degrees is appropriate. Because the adsorption performance of tea is relatively good, it should not be stored with other foods that are easy to produce peculiar smells, and the tea should be stored in clay pots or tin pots before storage, and sealed well after taking the tea every time, so as to avoid too much contact with air than the tea, and also maintain the color and taste of the tea.

Tea leaves can be kept fresh in the refrigerator, and they can be stored for a longer time, so that the tea leaves will not change their taste.

1. Whether the tea is put in the refrigerator is related to the degree of fermentation, there is a relatively simple way: unfermented and lightly fermented tea should be put in the refrigerator, intuitively speaking, it is green tea. It contains all green teas, such as Longjing, Biluochun, Maofeng, Anji White Tea, etc., as well as lightly fermented fragrant Tieguanyin, fresh varieties of Fuding White Tea, Baihao Yinzhen, White Peony, etc.

Black tea, Pu'er tea, flower tea, and strong aroma Tieguanyin, these teas with a relatively high degree of fermentation do not need to be put in the refrigerator, and generally follow several principles: sealed, protected from light, dry, and no peculiar smell.

2. The purpose of putting tea in the refrigerator is to reduce the speed of oxidation reaction of the components in the tea and prevent the aging of the tea and the deterioration of the aroma.

For example, green tea and fragrant Tieguanyin contain more active substances, which are more susceptible to the storage environment, especially the effects of temperature and moisture changes. At minus 5 degrees Celsius, the oxidation rate of tea becomes very slow, which greatly delays the deterioration rate of tea leaves; At minus 20 degrees Celsius, oxidation is minimal.

Therefore, green tea and fragrant Tieguanyin should be stored in the refrigerator, and they should be frozen. The refrigerator compartment of the refrigerator is generally 0-5 degrees, although it is better than room temperature, but there is a certain humidity, and the oxidation of tea leaves will still occur slowly, affecting the shelf life. If the amount is small, you can drink it at any time on weekdays, and you can also put it in the refrigerator; If it is a tea with a large amount of bulk, it is best to be able to separate small packages, otherwise frequent opening and closing in and out of the freezer will easily absorb water vapor and accelerate deterioration.

Precautions for refrigerator storage: sealed, anti-channeling.

Tea leaves are highly hygroscopic and taste-absorbent, so they must be sealed. And it's best to keep it on its own, not with smelly items.

It can reduce the reaction rate of oxidation of the components in the tea, prevent the aging of the tea and the deterioration of the aroma, and can better play a certain preservation effect. Generally, whether the tea leaves are put in the refrigerator or not is related to the degree of fermentation, and not all tea leaves are suitable for putting in the refrigerator. In general, green tea is best stored in the refrigerator.

Generally, the tea leaves stored in the refrigerator are usually relatively fragrant and have a low degree of fermentation, and are easy to deteriorate, such as green tea, Longjing, Tieguanyin, etc.

For tea leaves suitable for storage in the refrigerator, it is recommended to set the temperature to about minus 5 degrees Celsius, at which time the oxidation rate of tea will become very slow, which also greatly delays the deterioration rate of tea leaves.

Tea leaves can be stored in the refrigerator, but it is important to note that not all teas are suitable for storage in the refrigerator. There will be different ways to store different types of tea. Some teas are suitable for frozen storage in the refrigerator, while others are not. The details are as follows:

Tea leaves suitable for storage in the refrigerator:

Green tea, fragrant oolong tea, and dehumidifying tea. Among the six major types of tea, green tea is the most likely to deteriorate, and extra attention is required when preservation, you can put the tea leaves in the tea canister and seal it, cover it in a sealed bag and put it in the refrigerator; In addition, the fragrant Tieguanyin and the dehumidifying tea that is more popular in the oolong tea can be stored in the refrigerator.

Green tea, fragrant oolong tea, and dehumidifying tea are suitable for storing in the refrigerator.

Tea leaves that are not suitable for storage in the refrigerator:

Black tea, Pu'er tea and white tea are naturally due to the later transformation, especially Pu'er tea, which pays attention to the drinking value reflected in the later aging.

Putting these two types of tea in the refrigerator, in addition to the above-mentioned moisture problem, in the low temperature environment of the refrigerator, the activity of biological enzymes in the tea will also decrease, which will affect the efficiency of tea transformation.

Jasmine tea due to its own aroma, if placed in the refrigerator, its aroma will gradually become weaker.

But there is a special case here, which is the snow in Bitan. Because Bitan Piaoxue added jasmine in the later stage of the production process, it is appropriate to put it in the refrigerator, which is conducive to the preservation of the fragrance of flowers, but the aroma will also be lost after long-term storage.

Tea leaves stored in the refrigerator as appropriate:

Temperature has a great influence on the storage quality of black broken tea, and the quality component of tea leaves is stored at a lower temperature (0-5) for one year, and the quality composition changes little, and the moisture only increases. After one year of storage, the reduction of theaflavins content was 18 times higher than that of low-temperature treatment, while the increase of theabrownin was doubled. This makes the tea leaves stored at low temperature still fresh and mellow, while the tea stored at room temperature turns brown and the fragrance becomes dull.

Therefore, because black tea is a fully fermented tea, it is allowed to be stored at room temperature in most cases, and it has little impact on the quality of tea.

Some high-quality, delicate raw materials of Duanluzhong black tea, usually have a higher content of theaflavins, in the case of sealing, it can be stored in the refrigerator at a low temperature for a period of time. This is beneficial for slowing down the browning rate of black tea.

Precautions for storing tea leaves in the refrigerator:

In the family, if it is not a refrigerator specially used to store tea, some other food will generally be placed, and tea is extremely easy to absorb flavor, so when storing, be sure to wrap the tea leaves.

In the case of loose tea, it is recommended to put the tea leaves in a clean, odorless sealed bag and tea canister before storing them in the refrigerator. If it is non-loose tea, it is recommended to check whether the sealing of the tea package is good, and then put a clean sealed bag, so as to avoid the taste of the tea mixed with other things.
