Tea scale is actually caused by our neglect of the teapot and the cleanliness of the teapot after drinking tea. Every time we make tea, we should wash the teapot and teapot with boiling water, which can reduce the formation of teapot scale. When tea stains appear, we can remove them with eggshells or wash them with lemon, because citric acid can neutralize tea stains, thus solving troublesome tea stains. We can learn how to remove tea stains, because now middle-aged and elderly people like a healthy life.
So many people pursue good tea. Some foreign researchers have found that the tea residue formed by soaking a bag of British black tea at a time is more than that formed by soaking two bags at a time. Even five bags at a time will not form tea residue, which may be because polyphenols in tea reduce the ph value of tea soup. Another patent achievement is that a small amount of citric acid is added to the tea bag to adjust the taste and reduce the consumption of tea. In addition, calcium ion is the key factor to form tea scale.
It promotes the oxidation of tea polyphenols and plays a cross-linking role in the polymerization process. The harder the water is, the more tea dregs there are. The hardness of groundwater is greater than that of surface water, and the tea residue formed by making tea with pure water is much less. Making tea with tap water can completely boil the water for a few minutes, and the calcium and magnesium in it will form carbonate water base, which can reduce the formation of tea scale. ?
Finally, there are more and more people who love tea in the above life, so let's analyze how to remove tea stains here today.
