    Product Overview:

    Gallic acid (GA) is a component of hydrolyzable tannins, also known as gallic acid, and its chemical name is 3,4,5-trihydroxybenzoic acid. The content of gallic acid in Yunnan Pu'er tea is relatively high, and it has multiple biological effects such as antibacterial, anti-inflammatory, anti-tumor, and anti-mutation.

    Gallic Acid powder Usage and Synthesis.

    Gallic acid itself has significant antioxidant effects, and also has many other effects such as anti-tumor, trypanosome killing, liver protection and anti-hepatitis B virus. Recent studies have pointed out that gallic acid may be one of the effective components of Pu'er tea that inhibits the synthesis of cholesterol in HepG2 cell lines.

    On the overall level, the gallic acid content in Pu'er tea (9.01 mg/g) is higher than that of some other plant Chinese medicinal materials. In this sense, gallic acid is one of the important physiologically active components of Pu'er tea.

    Uses and functions of Gallic Acid.

    Gallic acid has many uses in pharmaceuticals, inks, dyes, food, light industry and organic synthesis. Gallic acid and trivalent iron ions generate blue-black precipitates, which are the raw materials of blue-black ink; they are also used in leather making in industry; they can also be used as photographic developers.

    Propyl gallate is an antioxidant and can be used in edible oils to prevent rancidity and deterioration. In medicine, gallic acid is a hemostatic astringent and a mild local irritant.

    It has antibacterial effects and can treat bacillary dysentery. It has astringent, hemostatic and antidiarrheal effects. It can be used as a preservative. It can prepare pyrogallic acid, drugs, inks, mordant dyes and explosion-proof agents.

    It is also used as a developer and an analytical reagent for detecting free inorganic acids, dihydroxyacetone, alkaloids and metals.

    Gallic Acid

    Advantage of Gallic Acid.

    Product Method of Bulk Gallic Acid.

    Made from gallnut. The main component of gallnut is tannic acid, which belongs to the hydrolyzed tannin, soluble in hot water, has astringent taste, and is an amorphous complex organic matter.

    my country's gallnut tannic acid is a complex mixture of gallic acid, digallic acid and glucose in the form of glycosides or esters. Tannic acid generates gallic acid and glucose by pressurized hydrolysis.

    During hydrolysis, gallic acid ester is first generated, and then digallic acid ester is hydrolyzed into gallic acid. The hydrolysis temperature is 133-135℃ and the pressure is 0.18-0.2MPa.

    The reaction starts from the pressure increase to 0.18MPa and is maintained for 2h to reach the end point. Compared with normal pressure hydrolysis, it can save sulfuric acid and steam, and the production capacity can be increased by 25%.
