Can you still drink tea from a purple sand teacup overnight?

It is often assumed that overnight tea should not be drunk. Tea will turn reddish-brown after being left for a long time, in fact, this is due to the oxidation of tea polyphenols into reddish-brown tea pigments. Studies have shown that tea polyphenols and tea pigments have strong anti-cancer and antioxidant effects, although the content of vitamin C in overnight tea is greatly reduced, but it still has anti-disease effects.

However, the temperature is high in summer, and the tea is easy to turn rancid, so if it is left for more than 24 hours, it is best not to drink it, otherwise it will cause diarrhea. Overnight tea that has not deteriorated can not only be drunk, but also has the following uses: 1. Hemostasis

Overnight tea is rich in tannic acid, which can accelerate blood coagulation. Oral bleeding can be rinsed, **bleeding can be used for bathing. Second, the eye:

The tea polyphenols in overnight tea have antibacterial and anti-inflammatory effects, and if red threads appear in the eyes, you can wash them with overnight tea several times a day. 3. Solid teeth cleaning: After calcifying the fluorine in tea and the enamel of the teeth, it will enhance the resistance to acidic substances and reduce the occurrence of tooth decay; Fluoride can also eliminate plaque, and it is best to rinse your mouth with tea two or three minutes after eating.

4. Bad breath: Tea contains essential oils, the smell is fragrant, and regular gargling with tea can eliminate bad breath. 5. Anti-itching:

Wash your hair or wipe your body with warm overnight tea, the fluoride in the tea can quickly relieve itching and prevent eczema. 6. Sunscreen: **If you are sunburned by the sun, you can gently wipe it with a towel dipped in overnight tea.

Because tannic acid has an astringent effect on **, the flavonoid compounds in tea also have an anti-radiation effect. It is only a wrong point of view to make tea overnight in a pot to raise a pot, I am a senior tea artist, and I have heard a lot of arguments about this, but in fact, this kind of tea left in the pot to achieve the purpose of raising a pot is wrong. You can pour the water from the tea wash or tea into a fair cup during the brewing process and rinse the body of the pot.

Or pour the rest of the tea you drink on the body of the pot to achieve the purpose of raising the pot, of course, I mean the same kind of tea, you can't use oolong tea to pour the body of the purple clay pot for brewing Pu'er tea. Brewing more tea is actually raising a pot, just like two pots of the same type, a half-year pot and a one-year-old pot are obviously different. A one-year-old pot is obviously more delicate and glossy than a half-year-old pot in appearance.

You can't drink it for the following reasons:

After the tea is left overnight, the color deepens. It is because of the further oxidation of tea polyphenols.

A cup of clear and turquoise tea, especially if left for a long time in high temperatures, will lose its green color and increase the degree of yellowness.

This is the oxidation product of the oxidation of tea polyphenols in tea to form yellow-red and reddish-brown, mainly theaflavin, thearubigin, theabrownin, etc.

Tea leaves contain nitrosamines, which are carcinogens that increase the formation of nitrosamines when left overnight.

The weather is getting colder and colder, and the thermos cup is beginning to come in handy, and many friends will use the thermos cup to make tea and drink, so can the tea brewed in the thermos cup be drunk overnight? What kind of things can be soaked in a thermos cup? Let's take a look.

Can you still drink tea made in a thermos cup overnight?

No. If you leave it overnight, you can observe the bottom of the cup to see if there are granular dots, and if there is something similar, it is best not to drink it. If there are no other impurities, you can drink it if you are more thirsty.

Of course, it is best to make tea again, and do not make the body feel uncomfortable because of this water.

Long-term storage of water in the thermos cup will cause deterioration, and the duration of this time is affected by the objective environment. After pouring boiling water into the thermos cup, it is in a sealed state, and it is generally no problem to store it for three days, because the boiling water in the thermos cup is in a clean and sealed state, and it will not deteriorate for three days, but the water temperature will become cold. And if the tightness is poor, the corresponding shelf life.

It will also decrease.

If it is stored properly, the overnight tea can be drunk, the thermos cup tea affects the taste, we cup tea, the tea is kept at a high temperature for a long time, it is not good, the oleic acid in the cold night, theophylline overflows a lot, resulting in the investigation of his too strong, the bitter and astringent taste increases, and the taste is not good.

If it is plain water, it can be drunk overnight in a sealed state.

Because the boiled water is sterilized at high temperature, there are fewer microorganisms, and it can be drunk on the first day. If the thermos cup is open, it is best not to drink, because there will be some mosquito activity at night, if these mosquitoes lay eggs on the thermos cup, it is easy to drink cold boiled water with mosquitoes when drinking water the next day.

How long can you keep the water in the thermos cup.

Pour boiling water in the thermos cup at night may not be able to drink it that night, the next day the water will become overnight water, overnight water in a sealed state is best drunk the next day, to the third day after it is not recommended to drink, although the boiling water has been sterilized at high temperature, but the overnight water will be in contact with the air, after two nights will produce a large number of microorganisms, easy to produce nitrite, so more than three days after it is not recommended to drink.

The thermos cup can't hold anything.

Milk. However, because milk is rich in nutrients, vitamins and other nutrients are easy to be destroyed at high temperatures, and the microorganisms in it are also easy to multiply rapidly at the right temperature, resulting in spoilage, diarrhea and abdominal pain.

Juices with high acidity.

The juice should not be kept at a high temperature in the first place, so as not to destroy the vitamins. In addition, fruit juice with high acidity is also easy to react with the inner wall of the thermos cup, which affects human health.

This generally does not drink overnight tea, overnight tea, then this may increase the probability of carcinogenicity, it is best to make tea on the same day, drink the tea of the next day on the same day, it is best to replace the gun, and then drink this may be more scientific.

If you can make sure that the tea has not spoiled, or if you have not had diarrhea after drinking the tea, you can drink it overnight. The purple clay pot in the tea set is precisely because of its unique air permeability and can keep the tea for a long time and should not deteriorate, which is deeply loved by tea drinkers. Purple sand is a porous material with a double pore structure, with fine pores and high density, and is fired at high temperature to make it breathable and impermeable.

However, it should be noted that it is not easy to deteriorate compared to other tea utensils, even if the tea brewed in the purple clay pot cannot ensure the quality for more than 24 hours, and it is not suitable to drink at this time.

If the overnight tea is left for too long or in the summer high temperature period, the tea is easy to become rancid and tasteful. At this time, not only vitamins and other nutrients have been lost, but also the proteins and sugars in the tea have oxidized and decomposed, and become nutrients for bacteria and molds to multiply, resulting in the deterioration of tea. This spoiled tea must not be consumed, otherwise it will cause diarrhea.

It should be noted that according to the individual's physique, the tolerance to spoiled tea is different. It may not matter if some people drink the same pot of tea, but people with sensitive gastrointestinal tract or the elderly and children may have adverse reactions. Therefore, it needs to be analyzed on a case-by-case basis.

Personally, I don't think you can drink tea overnight, and the tea should be warm before drinking, but after reheating, the mellow is no longer there.

The concept of overnight tea is: tea that has been left for more than 12 hours can be called overnight tea.

Brew tea with cool white and drink it the next day, it is best.

The newly bought pot can, if the old pot is not as much as possible, from a health point of view, after the purple clay pot has been brewed on the same day, the tea should not be put for too long, 1 2 days will definitely be no problem, and it will not be rancid, only in this way the pot is clean and has its own Yaguang. If the tea will be spoiled for 1 or 2 days, then there must be something wrong with the purple clay pot.

You can put it, you can't drink it, but you can use tea water to raise the pot It will look very good.

This is a pot, but you can't drink it, and you can't stay overnight.

Of course, you can put it, but you can't drink tea.

Absolutely. 1. Thoroughly wash the inside and outside of the pot. Whether it is a new pot or an old pot, remove the wax, oil, dirt, and tea dirt on the body of the pot before raising.

2. Do not get oily. The purple clay pot is the most resistant to oil stains, and it must be cleaned immediately after dipping, otherwise the soil tire will not be able to absorb the tea, leaving all the oil marks.

3. Make real tea. The more times the tea is brewed, the more tea juice the pot absorbs, and the soil tire absorbs to a certain extent, and it will penetrate the surface of the pot to emit a moist and jade-like light.

4. Wipe and brush moderately. After the tea juice is poured on the surface of the pot, use a small brush with soft bristles to brush the tea pins in the pot, rinse it with boiling water, and then use a clean tea towel to wipe it slightly, and do not keep pushing and rubbing.

5. Clean up and dry after use. After brewing the tea, the tea residue should be removed to avoid peculiar smell, and it needs to be reorganized.

6. Let the pot have time to rest. After brewing for a period of time, the teapot needs to rest, so that the soil tire can be dried naturally and thoroughly, and it can be more absorbed when it is used again.

According to these six steps to raise the bright pot, although the speed of cultivation is slow, but the brightness can last, and it is not afraid of human hand touch.
