In addition, Tannic Acid has passed by SGS and FDA registration.

Use of tannic acid in food applications is far more widespread and significant amounts are used as process aids in beer clarification, aroma compound in soft drinks and juices. Equally important are applications in the wine industry, where it finds use as a natural clarifying agent, colour stabilizer and taste enhancer.

Tannic acid is still used in pharmaceutical applications to produce albumin tannate which is used as an antidiarrheal agent. Tannic acid is also used to produce tannate salts of certain antihistamine and antitussive products to impart increased stability or slow release properties to the active pharmaceutical ingredient. Further to this, tannic acid is the principle but perhaps minimally effective ingredient in antiallergen sprays.

Tannic acid is a common mordant used in the dyeing process for cellulose fibers such as cotton, often combined with alum and/or iron. The tannin mordant should be done first as metal mordants combine well with the fiber-tannin complex.

Tannic acid is used in the conservation of ferrous (iron based) metal objects to passivate and inhibit corrosion. Tannic acid reacts with the corrosion products to form a more stable compound, thus preventing further corrosion from taking place. After treatment the tannic acid residue is generally left on the object so that if moisture reaches the surface the tannic acid will be rehydrated and prevent or slow any corrosion.
