Gallic acid, also known as pentaxic acid or zirtic acid, is an organic acid found in five times, golden plum, lacquer trees, oak bark, tea. No-eating acid is soluble in water, alcohol and ether, has the properties of phenols (easy to oxidize and iron trichloride solution to produce blue-black precipitation) and carbox acid (loss of carbon dioxide cokeless no-eating acid when heated).

No-eating acid can be used as a development agent, its alkaline tantalum salts are used as preservatives, often used in the pharmaceutical industry. It is the raw material used to make the hallucinogen Mescaline.

Acid method, alkali hydrolysis production of non-food acid is currently the most commonly used two production methods, acid method is directly used to hydrolyzed five times sulfuric acid in tannins, its technical characteristics are used less accessories, high purity, no food acid activity, good quality, but the product contains a small amount Sulfate ions, production is not easy to control, prone to hydrolysis overhead, hydrolyzed non-food acid action to produce coking no oesotic acid and other substances, resulting in the solubility of non-food acid plus, dark, less yield.
