Propyl gallate Usage And Synthesis
Description Propyl gallate (also known as propyl 3, 4, 5-trihydroxybenoate) is a kind of ester formed through the condensation of gallic acid and propanol. It appears as a fine white to creamy-white crystalline powder. It has long been used as a kind of antioxidants to be supplied to foods especially animal fats and vegetable oil, being especially effective with polyunsaturated fats. Propyl gallate, as an anti-oxidant, can protect the food and oils from the attack of hydrogen peroxide and oxygen free radicals, having an effect similar to the superoxide dismutase. It can also be applied to ethers, emulsion, waxes, and transformer oil as the antioxidants.
