Can you drink tea overnight, can you continue to 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.

Normally, overnight tea is used to gargle or drink in the morning, but from a nutritional and hygiene point of view, the vitamin C and other nutrients in the tea soup will be reduced due to gradual oxidation after the tea field has been left for a long time. In addition, at high temperature, placed for a long time, the proteins and sugars in the tea are the medium of bacteria and molds, which are easy to breed molds and bacteria, resulting in the deterioration and corruption of the tea soup, and of course the spoiled tea soup cannot be drunk.

Whether overnight tea can be drunk depends on personal understanding of "overnight tea", generally speaking, from the perspective of nutrition or tasting, tea brewing and drinking should be brewed and drunk.
