Product Name:Propyl Gallate
English Name:Propyl Gallate
CAS No.:121-79-9
Aliases:Gallic acid propyl ester, 3,4,5-Trihydroxybenzoic acid propyl ester, n-Propyl gallate, PG
Molecular Formula:C10H12O5
Physical Properties:White or off-white crystalline powder, sparingly soluble in water, slightly soluble in cottonseed oil, peanut oil and lard, freely soluble in ethanol, ether and propylene glycol. The pH of a 0.25% aqueous solution is about 5.5. Melting point approximately 146~150°C. It produces purple or dark green color with copper, iron and other metal ions, is hygroscopic, unstable to light, and has poor heat resistance.
Uses:Primarily used as a food antioxidant to prevent, inhibit or delay oxidative rancidity of oils and fats, thereby improving the stability and shelf life of food products. It is widely applied in edible oils, fried foods, dried fish products, fat-rich biscuits, canned foods and cured meat products. In addition, studies have shown potential pharmacological effects in treating cardiovascular and cerebrovascular diseases, inhibiting platelet aggregation, and dilating blood vessels.
