The Correlation Between Quality Changes and Skin Thickness of the Stored Citrus Fruit

Abstract

The storage time of citrus fruit at two different storage temperatures was predicted by quality changes such as weight loss, %Brix and skin thickness. The less weight loss of citrus fruits during storage at $3^{\circ}C$ was observed, compared to those stored at $25^{\circ}C$, whereas %Brix of citrus fruits increased slightly without any difference between storage temperatures. Skin thickness of fruit, represented by pixel, also changed more rapidly at the higher storage temperature. Above parameters with a storage time followed the 0 order reaction pattern. The relationship of skin thickness and storage time of the citrus fruit were resolved to a simple linear equation, and storage time could be predicted using this equation.

서로 다른 온도($3^{\circ}C와\;25^{\circ}C$)에서 저장한 감귤류에서의 과피 두께와 품질변화간의 상관관계를 살펴보았다. $3^{\circ}C보다\;25^{\circ}C$에서 저장한 감귤의 중량손실은 컸으나 당도(%Brix)는 저장온도에 상관없이 일정하게 증가함을 보였다. 픽셀로 표현되어지는 과육의 두께도 높은 저장온도에서 급격하게 변화됨을 보였다. 위와 같은 성분들은 시간에 따른 0차 반응속도로 분석한 결과 각 온도에서의 반응상수들이 구하여졌다. 과육의 두께를 회기선형모델에 적용한 결과, 저장기간을 예측할 수 있었고 그때의 중량감소나 당도변호가 과육 두께의 함수로 표현되어질 수 있었다.
