Gallic acid is a naturally occurring polyphenolic organic acid with the chemical formula C₇H₆O₅. Widely found in plants such as Chinese nutgalls, tea leaves, and various fruits, it possesses antioxidant, antibacterial, and anti-inflammatory properties and is commonly used in the pharmaceutical, food, and chemical industries.
It appears as a white to pale yellow crystalline powder; it is sparingly soluble in water but soluble in organic solvents. It is strongly acidic, prone to oxidation (forming quinone-like substances), and decomposes at high temperatures. Primary sources include Chinese nutgalls (galls formed by insect parasitism), tea leaves (especially green tea), pomegranates, and oak bark.
Microbial synthesis: Certain fungi and bacteria can produce gallic acid through metabolic pathways.
Application
Antioxidant: Scavenges free radicals and delays oxidative damage to cells.
Antibacterial and anti-inflammatory: Used to treat skin infections, oral ulcers, etc.
Pharmaceutical synthesis: Serves as a precursor for synthesizing tannic acid, Vitamin C, etc.
Preservative: Inhibits microbial growth and extends shelf life.
Flavor stabilizer: Prevents the oxidative rancidity of fats and oils.
Dye fixative: Used in textile dyeing and leather tanning.
Photosensitive material: Used in the preparation of semiconductors and photoresists.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
