Penentuan Gejala Chilling Injury Buah Belimbing (Averrhoa Carambola L.) yang disimpan pada Suhu Rendah

Abstract

In this study, the changes in quality of star fruits stored in low temperature was examined and the chilling induced of star fruits during storage period was examined by the changes in the rate of ion leakage. The quality of star fruits during storage was examined through the changes in respiration rate, firmness, total soluble solid, weight loss, ion leakage, and visual appearance daily. The sample of star fruits were stored at three different temperatures, i.e. 5 and 10 oC and room temperature. Ion leakage was determined by calculating the slope of percentage of total ion leakage with time. It was resulted that the peak of the rate of ion leakage for fruits stored at 5 ºC was found after 1 day storage. The increase in the rate of ion leakage indicates the chilling induced of cell membrane. This chilling injury caused the fruits has the quality lower than that fruits stored at 10ºC after period of time which was indicated by the lower total soluble solid.
