All treatments were stored at 5°C and 90-95% RH for 60 days followed by shelf life at 20°C for 14 days. CaCl2 at 2% significantly maintained fruit weight, peel thickness and fruit firmness. Also, 1% chitosan alone or + 2% CaCl2 showed the lowest significant decay percentages. Furthermore, 1% chitosan exhibited the lowest significant respiration rate, h° score and TSS value, it showed the highest significant general appearance scores, and maintained the higher contents of ascorbic acid and anthocyanin pigment compared with untreated ones
