1. Product Overview
Tannic acid is a typical water-soluble plant tannin, belonging to natural plant polyphenol compounds, which is distinctly different from insoluble condensed tannins. Sourced from high-quality Galla Chinensis, our tannic acid powder features high purity, good water solubility and stable chemical properties. As verified by Cornell University Department of Animal Science, plant tannins can bind and complex with proteins, endowing tannic acid with unique astringent, antibacterial and antioxidant activities.
Widely existing in natural foods such as tea, fruits, wine and edible forage, tannic acid is a safe and efficient natural functional ingredient. Our product adopts professional plant extraction and purification technology, reaching medicine-grade standard, and is applicable to pharmaceutical, food, cosmetic, feed and industrial fields.
