Abstract

Having a very thick rind which is frequently believed as a good physical barrier to fruit deterioration from a high transpiration rate, the mangosteen fruit hardly receives any postharvest technology to lengthen its fruit shelf-life and maintain its high fruit qualities. This research was aimed at studying postharvest applications of sugar-esther blend of KD-112 and plastic wrapping applied to different fruit stages in affecting fruit shelf-life and qualities of mangosteen. This study used a Completely Randomized Design with five replicates arranged in a factorial 4 × 3 × 2. The first factor was mangosteen fruit stage (stage 0, 2, 3, and 4), the second one was KD-112 (0, 7, and 14%), and the third one was plastic wrapping (without and with one layer of plastic wrapping). The results showed that by harvesting mangosteen at younger fruit stages 0 and 2, its fruit shelf-life extended significantly up to 3-5 days longer compared to harvesting at later stages. However, because there might be a risk of misjudge in determining the physiological maturity when the fruits were still at stage 0, stage 2 seemed to be the most appropriate stage for harvest. A single treatment of KD-112 was able to extend fruit shelf-life by 4-6 days longer and to increase fruit firmness by 4-5 kg/cm2 firmer than the control. A single plastic wrapping treatment was able to extend fruit shelf-life by 5 days longer than the control. By combining both treatments of 14% KD-112 and plastic wrapping, and applied to fruit stage 2, fruit shelf-life of 21 days could be achieved, that was 8 days longer than fruit of the youngest stage receiving no fruit coatings, while its fruit qualities were not affected.
