Tannins are a broad class of complex phenolic compounds that are comprised of two chemical groups the hydrolyzable tannins (gallotannins) and the condensed tannins (proanthocyanidins). Tannins bind to and precipitate proteins, producing the astringent activity of tannin-containing herbs. Tannins are natural components of many herbs and common foods, and some tannins are used in the processing of foods, alcoholic beverages, and medicines. [Pg.966]

Red fruits such as strawberries, raspberries and blueberries, black tea, red wine and nuts are the main sources of gallic acid and ehagic acid (Tomas-Barberan and Chfford 2000). These phenolic acids exist in free form or as components of complex structures such as hydrolysable tannins (gallotannins in mangoes and ehagitannins in red fruits (Clifford 2000 also see Chapter 7). [Pg.323]
