Synergistic with other antioxidants such as Butylated hydroxyanisole <ht>DNB28-K</ht> and 2,6-Di-tert-butyl-4-methylphenol <ht>HCH42-H</ht>. Especies 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. Propyl gallate is found in corn. 3,4,5-Trihydroxybenzene-1-propylcarboxylate 3,4,5-Trihydroxybenzoic acid n-propyl ester 3,4,5-Trihydroxybenzoic acid propyl ester 3,4,5-Trihydroxybenzoic acid, propyl ester Benzoic acid, 3,4,5-trihydroxy-, propyl ester E310 FEMA 2947 Gallate, propyl Gallic acid n-propyl ester Gallic acid propyl ester Gallic acid, propyl ester n-Propyl 3,4,5-trihydroxybenzoate n-Propyl ester of 3,4,5-trihydroxybenzoic acid N-propyl gallate n-Propyl-3,4,5-Trihydroxybenzoate N-propyl-gallate Nipa 49 Nipagallin p Nipanox S 1 PG Pro gallin p Progallin p Propyl 3,4,5-trihydroxybenzoate Propyl galiate Propyl gallate Propyl gallate (NF) Propyl gallic acid Propylester kyseliny gallove Sustane PG Tenox PG C10H12O5 212.1993 212.068473494 propyl 3,4,5-trihydroxybenzoate propyl gallate 121-79-9 CCCOC(=O)C1=CC(O)=C(O)C(O)=C1 InChI=1S/C10H12O5/c1-2-3-15-10(14)6-4-7(11)9(13)8(12)5-6/h4-5,11-13H,2-3H2,1H3 ZTHYODDOHIVTJV-UHFFFAOYSA-N belongs to the class of organic compounds known as galloyl esters.
