Abstract

This study was carried out to investigate the effect of storage period on flavor components of Korean kiwifruits (Actinidia deliciosa Planch.) stored at $20^{\circ}C$. The major volatile components of Korean kiwifruits analyzed by GC and GC-MS were pentanal, methyl butanoate, ethyl pentanoate, heptanone, (E)-2-hexenal, ethyl hexanoate, 1-hexanol, cyclohexanol, butyl hexanoate, linalool oxide, linalool, butyl heptanoate, methyl benzoate, ethyl benzoate. Among them, (E)-2-hexenal was the major component in premature fruit but on further ripening ethyl butanoate began to dominate the component profile.

한국산 양다래의 저장기간이 향기성분의 변화에 미치는 영향을 구명하고자 $20^{\circ}C$ 저장시료의 향기성분의 변화를 저장기간별로 측정하여 비교하였다. 동시증류 추출방법에 의해서 pentanal, methyl butanoate, ethyl butanoate, hexanal, propyl butanoate, ethyl pentanoate, heptanone, (E)-2-hexenal, ethyl hexanoate, 1-hexanol, cyclohexanol, butyl hexanoate, linalool oxide, linalool, butyl hepatanoate, methyl benzoate, ethyl benzoate가 GC/MS로 동정되었다. 저장기간에 따라 (E)-2-hexenal과 ethyl butanoate의 함량변화가 많았다. 숙성이 되지 않은 상태에서는 풋풋한 향기의 원인물질인 (E)-2-hexenal이 다량 존재하였으나 ethyl butanoate는 발견되지 않았다. 그러나 숙성과정이 진행됨에 따라서 (E)-2-hexenal은 감소하였으며 향긋한 과일향을 나타내는 ethyl butanoate는 급격히 상승하였다.
