Ethyl gallate is a food additive with E number E313. It is the ethyl ester of gallic acid. Ethyl gallate is added to food as an antioxidant.

Though found naturally in a variety of plant sources including walnuts[2] Terminalia myriocarpa[3] or chebulic myrobolan (Terminalia chebula),[4] ethyl gallate is produced from gallic acid and ethanol.[5] It can be found in wine.[6]
