국내에서 생식용 및 가공용으로 널리 재배되고 있는 5종류 품종, 백도ㆍ천도ㆍ유명ㆍ대구보 및 황도의 복숭아의 휘발성 향기성분을 SDE 방법으로 추출하고, 이를 GC와 GC/MS를 사용하여 분리 확인하였다. 복숭아의 품종별 즉 백도, 천도, 유명, 대구보 및 황도에서 83, 85, 70, 74, 66종의 휘발성 향기성분이 각각 동정되었다. 확인된 성분들은 29 알코올, 27 케톤, 18 알데히드, 9 에스터, 5 에테르, 3 유기산. 6 테르펜과 그
Volatile flavor components in five varieties, Bekdo, Chundo, Yumung, Daegubo and Hwangdo, of peach (Prunus persica L.) were extracted by SDE (Simultaneous steam distillation and extraction) method using the mixture of n-pentane and diethylether(1:1, v/v) as an extract solvent. Analysis of the concentrate by capillary gas chromatography and gas chromatography-mass spectrometry led to the identification of 83, 85, 70, 74 and 66 components in Bekdo, Chundo, Yumung, Daegubo and Hwangdo, respectively. Aroma patterns (29 alcohols, 27 ketones, 18 aldehydes, 9 esters, 5 ethers, 3 acids, 6 terpene and derivatives, and 26 miscellaneous) were identified and quantified in five cultivars. Ethyl acetate, hexanal, o-xylene, (E)-2-hexenal, hexanol, (E)-2-hexen-1-ol, benzaldehyde, r-decalactone and r-dodecalactone were the main components in each samples, though there were several differences in composition of volatile components. Beside C6/ compounds, a series of saturated and unsaturated r- and -lactones ranging from chain length C6/ to Cl2/, with concentration maxima for r-decalactone and r-dodecalactone, were a major class of constituents. Lactones and peroxidation products of unsaturated fatty acid (i.e. C6/ aldehydes and alcohols) were major constituents of the extract.
