4905 Propyl gallate Propyl gallate is found in corn. 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. Propyl gallate has been shown to exhibit pro-oxidant and radical scavenger functions (A7908, A7909). 121-79-9 4947 C10H12O5 White powder. 150 °C Decomposes 3.5 mg/mL at 25 °C No indication of carcinogenicity to humans (not listed by IARC). 2014-09-11T05:19:10Z 2014-12-24T20:26:58Z http://en.wikipedia.org/wiki/Propyl_3,4,5-trihydroxybenzoate C11155 D011435 true CCCOC(=O)C1=CC(O)=C(O)C(O)=C1 C10H12O5 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 InChIKey=ZTHYODDOHIVTJV-UHFFFAOYSA-N 212.1993 212.068473494 Exogenous Solid 1.80 HMDB33835 CHEMBL7983 4778
