Abstract

This study was conducted to evaluate quality characteristics of citron from Namhae. The physicochemical properties, organic acid, free sugar and aroma components were analyzed and compared with citron harvested in different areas of Namhae (Seolcheon, Changseon and Idong-meyon). Total weight of citron was range of 120.51~176.56 g, total and peel weight of citron cultivated from Changseon were significantly higher than the other citron. The color of peel was not significant in cultivated area. Soluble solids was higher in citron from Changseon and Idong than Seolcheon. Total phenol and flavonoids contents in citron from Idong were higher than the others. Organic acids such as citric acid and malic acid were higher in citron from Changseon. The contents of fructose and glucose in peel and sucrose in pulp were detected higher amount. Major component of aroma profiles in citron from different region of was dl-limonene. It was amount to 57.60% in citron from Idong, 71.02% and 73.04% in citron from Seolcheon and Changseon of all aromatic components. These results were suggested that physicochemical properties and aroma components of citron have some difference by cultivation habit, period, different cultivar and producing areas.

남해 유자의 품질 특성을 알아보기 위하여 남해군 설천, 창선 및 이동 지역에서 재배된 개량종 유자의 이화학적 품질 특성을 비교하였다. 유자의 총 중량은 120.51~176.56 g으로 창선 유자가 유의적으로 무거웠으며, 총 중량에 대한 과피의 비율도 가장 높았다. 과피의 표면색은 지역간에 차이가 작았다. 과육의 수분 함량은 시료간에 유의차가 없었으며, 당도는 창선 및 이동 유자가 설천 유자에 비해 유의적으로 높았다. 총 페놀과 플라보노이드 함량은 이동 유자에서 유의적으로 높았다. 유기산은 citric acid 및 malic acid 함량이 창선 유자에서 다소 높았으며, 유리당은 fructose와 glucose는 과피에서, sucrose는 과육에서 함량이 높았다. 유자의 향기성분 중 dl-limonene의 함유 비율이 가장 높았으며, 이동 유자는 57.60%, 설천 및 창선 유자는 각각 71.02%, 73.04%를 차지하였다. 이와같이 남해 지역에서 재배된 유자간에 이화학적 특성의 차이는 토양, 수확시기, 재배 조건 등의 영향이 주된 요인인 것으로 추정된다.
