확인시험

  이 품목 1mL에 수산화나트륨시액 7mL를 넣고 수욕 중에서 흔들어 섞으면서 가열하면 이 품목은 거의 녹아서 특이한 향기가 없어진다. 이 액을 묽은황산으로 산성화하여 수욕 중에서 흔들어 섞으면서 가열하면 지방을 분리하여 특이한 향기를 발생한다.

정량법

  이 품목 약 1g을 정밀히 달아 향료시험법 중 에스테르가 및 에스테르함량측정법에 따라 시험한다.

0.5N 알콜성수산화칼륨용액 1mL ＝ 78.11mg C₉H₁₆O₂

개요

γ-Nonalactone has a strong odor reminiscent of coconut and a fatty, peculiar taste. May be synthesized by reacting methylacry- late and hexanol in the presence of ditertiarybutyl peroxide; by condensation of undecylenic acid and malonic acid; by lactonizα- tion of nonenoic acid.

화학적 성질

gamma-Nonanolactone occurs in many foods and is a pale yellow liquidwith a coconut-like aroma. It has numerous applications, similarly to those of ??-octalactone, in aroma compositions and perfumery.

용도

(Gamma)-Nonalactone is a synthetic flavoring agent that is a colorless to yellow liquid of strong, coconut-like odor. It is soluble in most fixed oils, mineral oil, and propylene glycol. It is stable in acids and unstable in alkali and should be stored in glass, tin, or aluminum containers. It is used in coconut flavors and has application in gelatins, puddings, baked goods, candy, and ice cream at 11–55 ppm. It is also termed aldehyde c-18.

제조 방법

By reacting methylacrylate and hexanol in the presence of ditertiarybutyl peroxide; by condensation of undecylenic acid and malonic acid by lactonization of nonenoic acid

일반 설명

γ-Nonanoic lactone is an oak lactone commonly found in wines aged in oak barrels. It is the main flavor component of coconut. γ-Nonanoic lactone is also a potential multi-species attractant lure for grain beetle pests.

Safety Profile

Moderately toxic by ingestion. A skin irritant. Mutation data reported. Combustible liquid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALDEHYDES.
