Friends who have drunk Pu 'er tea know that Pu 'er tea will turn reddish brown if it is kept 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 resistance.
Cancer, anti-oxidation, although the content of vitamin C in overnight tea is greatly reduced, it still has anti-disease effect. Pu 'er tea can be drunk overnight, but under certain conditions.
1. Although Pu 'er tea can be drunk overnight, it should not be separated for too long. If it has been more than 24 hours, please give up.
Second, if you can't finish it today and want to enjoy it tomorrow, please follow the following steps:
1. The last bubble, completely empty the water in the pot. Generally speaking, the main reason why you can't drink overnight tea is that bacteria are easy to breed in the tea soup after a night, but it is unlikely to affect the tea itself (it is hard to say for more than 24 hours). Dry the water in the dry pot and keep the bottom of the leaves dry, and there will be no problem.
2. Cover the lid firmly and turn the pot upside down. The famous "broth bacteria test" tells us that it is bacteria in the air that make broth deteriorate. Here we turn the pot upside down, with the spout facing down, so as to avoid the bacteria at the bottom of the leaves as much as possible.
When you want to continue making tea the next day, pour boiling water into the pot twice, quickly pour it out, and you can continue to enjoy it. The purpose of quick tea washing here is to wash away as many bacteria as possible from the bottom of leaves, and also to avoid the waste of tea quality.
But it is not recommended to drink regularly:
Drinking tea advocates instant drinking, both from the perspective of health and taste. Whether overnight tea can cause cancer is currently recorded. Red and green tea contains a small amount of secondary amine, but it is not carcinogenic. However, if the temperature is right and the time is long, the tea soup will change color and even become sour due to the effect of vitamins. Especially in summer, overnight tea soup often turns dark or dark brown, a bit like.
