FooDB NameHeptanoic acid
DescriptionPresent in essential oils, e.g. violet leaf oil, palm oiland is also present in apple, feijoa fruit, strawberry jam, clove bud, ginger, black tea, morello cherry, grapes, rice bran and other foodstuffs. Flavouring ingredient. It is used as one of the components in washing solns. used to assist lye peeling of fruit and vegetables Heptanoic acid, also called enanthic acid, is an organic compound composed of a seven-carbon chain terminating in a carboxylic acid. It is an oily liquid with an unpleasant, rancid odor. It contributes to the odor of some rancid oils. It is slightly soluble in water, but very soluble in ethanol and ether.; Heptanoic acid, also called enanthic acid, is an organic compound composed of a seven-carbon chain terminating in a carboxylic acid.
