재래종 배의 휘발성 향기성분

Volatile Flavor Components from Traditional Cultivars of Pear (Pyrus pyrifolia N.)

  • 발행 : 2002.04.01

초록

SDE 추출법과 GC/MS 분석방법으로 재래품종인 봉리, 황실리, 영목리 배를 시료로 하여 각각 72종, 59종, 66종의 휘발성 향기성분을 분리 동정하였다. 모든 품종에서 ethyl acetate가 주요한 ester 화합물로 확인되었으며, 다량의 ethanol과 acetic acid가 함유되어 있었다. 황실리와 영목리에서 다량 확인된 nonanoic acid는 봉리에 소량 함유되었으며, 봉리에서 주요 성분으로 확인된 butyl acetate가 황실리와 영목리에서는 동정되지 않았으나, 황실리와 영목리에서는 단지 $4{\sim}5$개의 ester류가 전체 향기구성에 큰 비중을 차지하고 있었다. 또한 관능기로 분류하여 볼 때, 분리 동정된 성분들 중에서 봉리는 ester와 alcohol류, 황실리에서는 alcohol류 그리고 영목리에서는 ester, acid, alcohol류가 휘발성 향기성분의 조성에 큰 비중을 차지하고 있음을 보여주어 세 가지 재래품 종간의 휘발성 향기성분의 조성에 차이점이 있었으며, 서양배와 개량품종 배와도 차이점을 보여주었다. 봉리, 황실리, 영목리에서 추출된 휘발성 향기성분의 함량은 각각 6.069, 4.285, 6.552mg/kg을 차지하였다.
