| Questions and Answers (Q&A) | Back Directory | [Description]
Ethyl caprylate (ethyl octanoate) is a kind of fatty acid ester formed from caprylic acid and ethanol. It is a kind of natural fruit flavoring agent. It is usually included in the alcohol beverage. Among the main flavoring components of None-flavor liquor, the absolute content of ethyl caprylate is not high but its flavoring contributions is higher than ethyl acetate, ethyl lactate, and ethyl butyrate, only lower than ethyl caproate. Only small amount of ethyl caprylate could produce obvious fruit aroma in Nong-flavor liquor. However, excessive content of ethyl caprylate would inhibit the performance of other flavoring components.

Aliphatic esters including ethyl caprylate are thought to be readily hydrolysed to the corresponding alcohol and acid, which are then further metabolized (Fassett, 1963). Oral adminis tration of ethyl caprylate to rats produced a ketonuria twice as great as that from acetoacetate, indicating the formation of two fragments for the production of ketone bodies, and it was suggested that caprylic acid was probably broken down by a process involving multiple alternate oxidation (Deuel, Hallman, Butts & Murray, 1936). |
