Tannic acid also called tannic acid, is a polyphenol compound found in coffee, tea, persimmon, pomegranate and other plant tissues. These plants are particularly high in tannin content when plants are not yet mature period. The tannin structure is very complex, but it can usually be generated into hydrolysis of glucose, gallic acid or other acid polyphenols (tannins). Tannins is with taste of astringency in food, capable of forming a precipitate with protein, alkaloid, pectin, can form black substance with ferric iron.

Because of the tannins have above nature, it leads to many grams of food, such as eating seafood,at the same time, you can not eat grapes, hawthorn, pomegranates, persimmons and other fruits, otherwise there will be vomiting, abdominal distension, abdominal pain, diarrhea, etc.. Because these fruits contain tannic acid which will form precipitation after meeting protein from food, easily have the formation of digestible substances. Again, as after a meal not drinking tea, because the tannic acid in tea can be combined with the protein in food, generating non digestible sediment. In this propaganda, people have a very bad impression on tannin, think tannin is detrimental to the physical health of the material, so, will try to seperate the food containing tannin and protein. In fact, it is impossible to completely separate, and in real life, there is no strict adherence to this discipline. Such as some restaurants give the guests a fruit after the meal, but the guests did not feel uncomfortable. These reactions are only a loss of some nutrients, and the amount of loss is very small, so why do you make a fuss about it? What cause vomiting, stomach bleeding and anemia caused is just  exaggerated.

In fact, everything has two sides. We can not only see the negative side but ignored its favorable side. The tannin reacts with protein to form precipitate which is not digestible. Tt seems to be a waste of a portion of the protein, but from another perspective that the effect of tannin can inhibit obviously many kinds of bacteria, fungi and microbes, because tannins can be applied to bacteria, fungi and microbes, to solidify bacteria and microbe protein, and killed them. People often use tannin's sterilization and convergence effect, for the treatment of intestinal diseases, such as cholera, typhoid, dysentery, enteritis and so on; in addition, the tannin also has antiseptic effect on skin sores, festering pus, inflammation, oral ulcers, sore throat.
