Tannins are astringent, bitter plant polyphenols that either bind and precipitate or shrink proteins. The astringency from the tannins is that which causes the dry and puckery feeling in the mouth following the consumption of red wine, strong tea, or an unripened fruit[1]. The term tannin refers to the use of tannins in tanning animal hides into leather; however, the term is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as…

Enzymatic Browning of Model Solutions and Apple Phenolic Extracts by Apple Polyphenoloxidase
Model solutions containing chlorogenic acid (CG) and (-)-epicatechin (EP), and phenolics from nine apple cv., were oxidized with apple polyphenoloxidase (PPO). Browning was determined by absorbance
Inhibition of non-haem iron absorption in man by polyphenolic-containing beverages.
It is demonstrated that herb teas, as well as black tea, coffee and coca can be potent inhibitors of Fe absorption, and this property should be considered when giving dietary advice in relation to Fe nutrition.

Antibacterial Activity of Hydrolyzable Tannins Derived from Medicinal Plants against Helicobacter pylori
Hydlyzable tannins have potential as new and safe therapeutic regimens against H. pylori infection and it remains to be elucidated whether their membrane‐damaging activity directly contributes to their antibacterial action.
Iron absorption and phenolic compounds: importance of different phenolic structures.
The content of iron-binding galloyl groups might be a major determinant of the inhibitory effect of phenolic compounds on iron absorption from the diet, whereas the phenolic catechol groups seem to be of minor importance.
