Sign in to saveAlso known as E 324, E324, 2,2,4-Trimethyl-6-ethoxy-1,2-dihydroquinoline, Ethoxyquine, 1,2-Dihydro-6-ethoxy-2,2,4-trimethylquinoline, 6-Ethoxy-1,2-dihydro-2,2,4-trimethylquinoline, Ethyl 2,2,4-trimethyl-1,2-dihydro-6-quinolinyl ether, 1,2-Dihydro-2,2,4-trimethyl-6-ethoxyquinoline
Ethoxyquin (EMQ) is a quinoline-based antioxidant used as a food preservative in certain countries and originally to control scald on pears after harvest (under commercial names such as "Stop-Scald"). It is used as a preservative in some pet foods to slow the development of rancidity of fats. Ethoxyquin is also used in some spices to prevent color loss due to oxidation of the natural carotenoid pigments.

==Regulation== Ethoxyquin was initially registered as a pesticide in 1965 as an antioxidant used as a deterrent of scald in pears through post-harvest indoor application via a drench and/or impregnated wrap.
