説明
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.
化学的特性
CLEAR COLOURLESS LIQUID
天然物の起源
Reported found in apple, apricot, orange juice, grapefruit juice, guava, pineapple, cheddar cheese, other cheeses,
butter, beer, cognac, rum, whiskey, cider, grape wines, cocoa, coconut meat, passion fruit, mango, pawpaw and mastic gum leaf oil.
使用
Ethyl caprylate is a flavoring and fragrance agent.
製造方法
Usually prepared by esterification of caprylic acid with ethyl alcohol and sulfuric acid as catalyst; also by alcoholysis of
coconut oil in the presence of HCl.
定義
ChEBI: A fatty acid ethyl ester resulting from the formal condensation of octanoic acid with ethanol.
一般的な説明
Ethyl octanoate is a powerful odourant found in mead (a traditional drink that contains alcohol).
安全性プロファイル
Mddly toxic by
ingestion. A skin irritant. Combustible
liquid. When heated to decomposition it
emits acrid smoke and irritating fumes. See also ESTERS.
発がん性
Not listed by ACGIH, California
Proposition 65, IARC, NTP, or OSHA.
代謝
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).
