Propyl gallate is an antioxidant used in foods especially animal fats and vegetable oils. Synergistic with other antioxidants such as Butylated hydroxyanisole <ht>DNB28-K</ht> and 2,6-Di-tert-butyl-4-methylphenol <ht>HCH42-H</ht>. Especially effective with polyunsaturated fats. Indirect food additive arising from paper or board packaging, adhesives and food contact polymers Propyl gallate is an anti-oxidant. It protects against oxidation by hydrogen peroxide and oxygen free radicals, in a catalytic manner similar to superoxide dismutase. Propyl gallate, or propyl 3,4,5-trihydroxybenzoate is an ester formed by the condensation of gallic acid and propanol. It is an antioxidant added to foods containing oils and fats to prevent oxidation.[citation needed] As a food additive, it is used under the E number E310.\n\nPropyl gallate has been shown to exhibit pro-oxidant and radical scavenger functions (A7908, A7909)."}]
