tannic acid
tsca definition 2008: gallic acid derivatives found in nutgalls, bark and other plant parts, especially oak bark. Clarifying agent for beer and wine; flavour enhancer, colour modifier, pH control agent. Permitted boiler water additive in generation of steam for use in food contact processes Tannins are astringent, bitter-tasting plant polyphenols that bind and precipitate proteins. The term tannin refers to the source of tannins used 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 carboxyls) to form strong complexes with proteins and other macromolecules. Tannins have molecular weights ranging from 500 to over 3,000. Tannins are usually divided into hydrolyzable tannins and condensed tannins (proanthocyanidins). At the center of a hydrolyzable tannin molecule, there is a polyol carbohydrate (usually D-glucose). The hydroxyl groups of the carbohydrate are partially or totally esterified with phenolic groups such as gallic acid (in gallotannins) or ellagic acid (in ellagitannins). Hydrolyzable tannins are hydrolyzed by weak acids or weak bases to produce carbohydrate and phenolic acids. Condensed tannins, also known as proanthocyanidins, are polymers of 2 to 50 (or more) flavonoid units that are joined by carbon-carbon bonds, which are not susceptible to being cleaved by hydrolysis. While hydrolyzable tannins and most condensed tannins are water soluble, some very large condensed tannins are insoluble. Tannins may be employed medicinally in antidiarrheal, hemostatic, and antihemorrhoidal compounds. Also, they produce different colors with ferric chloride (either blue, blue black, or green to greenish black) according to the type of tannin. Examples of gallotannins are the gallic acid esters of glucose in tannic acid (C76H52O46), found in the leaves and bark of many plant species. Foods with tannins include tea, wine and some fruits (Wikipedia). [HMDB]

Odor: characteristic
Use: The tannic acids were found to show potent inhibitory activity against HIV RT. Thermally processed tannic acid (PTA) showed stronger antioxidant capacity and antimicrobial activity by Rancimat and disc diffusion tests than fresh tannic acid (FTA). Soybean oil treated with PTA had 33-84% longer induction period (IP) of oxidation (8.0-14.7 h) than FTA treated oil (6.0-8.0 h), while untreated oil (control) showed only 5.9 h IP. The IP was increased (p < 0.05) with increased processing time up to 15 min, with no changes thereafter. The PTA samples had strong antimicrobial activity (inhibition zone diameter 12 mm) on 10 tested human pathogens while the FTA samples showed antimicrobial activity only on two strains, Salmonella Typhimurium (ATCC 14028) and Enterobacter sakazakii MSDH over 1- and 2-day incubation periods. 13C NMR spectra showed that PTA had a higher content of hydrolysed aromatic carboxylic acid groups than FTA. The results showed that thermally processed tannic acid for 15 min had about 67% higher antioxidant capacity and about 50% higher antimicrobial activity than its fresh counterpart. Thermal processing could be useful for enhancing antioxidant capacity and antimicrobial activity of hydrolysable polyphenols in natural plants. Gallic acid was less toxic (w/w) than tannic acid. Comparison of urinary metabolites from rumen and abomasal administration indicated that decarboxylation and reductive dehydroxylation of phenolics occurred principally in the rumen and a significant proportion was totally degraded. Rumen metabolism appeared to prevent toxicity from gallic and tannic acid at dose rates of <0.4 g/kg liveweight per day.
