Original Article


Physico-chemical and sensory quality of juice from purple passion fruit under different storage temperature and time were assessed. The maximum loss in fruit weight was recorded under room temperature (25 ± 1°C) followed by at 11 ± 1°C. There was an increase in juice percentage up to 9 and 13 days under room temperature and storage at 11 ± 1°C respectively. The optimum flavour in juice was up to 5 days at 25 ± 1°C and up to 21 days at 8 ± 1°C. A significant reduction in sourness was recorded on 5th day under all treatments and the scores for sourness became almost constant after 17 days. The maximum increase in the mean scores of sweetness on 5th day was observed at 25 ± 1°C followed by at 11 ± 1°C. The optimum level of juice sweetness was maintained up to 21 days at 8 ± 1°C. Total soluble solids content increased in initial stage followed by reduction. There was a reduction in the titrable acidity up to 21 days at 8 ± 1°C. A decreasing trend in the reducing and non-reducing sugar of passion fruit was observed under all the treatments. Fruits stored at 25 ± 1°C, developed off-flavour in juice after 5 days, while storage at 8 ± 1°C produced no off-flavor even up to 21 days. Fruits can be stored for 5 days only at 25 ± 1°C as the overall sensory quality of juice reduced significantly afterwards, while juice maintained the optimum overall quality up to 21 days at 8 ± 1°C.
