Can you drink tea overnight? Can you drink tea overnight

I like to brew a pot of tea and drink it slowly, but I often can't finish it, so I can only leave it overnight and drink it again the next day. Many people say that overnight tea can breed bacteria and produce nitrite so it can't be consumed, is this true?

As long as it is stored properly, overnight tea is okay to use. Many people worry about nitrite production, but they don't have to. CCTV reporters have done experiments to send a cup of tea brewed for 12 hours, a cup brewed for 24 hours, and a cup of freshly brewed tea to the Beijing Institute of Nutrition Source for testing.

The results showed that the nitrite content of the tea with 12 hours and 24 hours and the freshly brewed tea did not change significantly, and the highest content was only about 1 4 of the national drinking water standard.

As for the breeding of bacteria, the sugar and amino acid content in tea is very low, and it is not a good "culture medium" for bacteria, and if the lid is closed, it is difficult for bacteria in the air to fall into the teacup, so there is no need to worry too much.

So how long can tea generally sit without spoiling? How to store tea well?

The question of how long it will spoil is not conclusive, which is closely related to factors such as the preservation environment, the condition of the tea, and the variety of tea, but if there is a peculiar smell or obvious changes in color and texture, it is better not to drink it.

It is recommended to close the container with a lid or plastic wrap for unfinished tea, and then put it in the refrigerator for storage, 8 12 hours will generally not deteriorate, after all, one of the fashionable cold brew tea preparation methods is to add cold water and tea leaves to the container, and then put it in the refrigerator to soak and extract for 8 hours.

The tea leaves made before going to bed at night, and when I got up the next day to drink them, the tea leaves did not deteriorate, and of course there was no problem with drinking. If the tea leaves are steeped for too long, especially if the temperature is high, it 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.

These products are non-toxic and do not cause harm to the human body. This change is day and night, and the temperature is higher during the day, and the change is a little bigger. But if the tea is soaked for too long, bacteria will breed and deteriorate, of course, you can't drink it, and it doesn't matter if you drink it for no more than 24 hours.

Tea will turn reddish-brown after being left for a long time, which 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 rancidity, so if it is left for more than 24 hours, it is best not to drink it, otherwise it will cause diarrhea.
