Changes in physical, chemical properties and antioxidant levels during postharvest ripening of ‘Frangi’ papaya (Carica papaya L.) were studied over a period of eight days after harvest. In general, a significant increase in weight loss (2.5–8%), lightness value (49.54–63.1), chroma (32.3–59.3), soluble solids concentration (7.9–17.6%), ascorbic acid content (169–322 mg 100 g−1 fresh weight (FW)), total phenolic content (0.515–0.686 mg GAE (gallic acid equivalents) g−1 FW), ethylene production (5.83–81.3 μl kg−1 h−1), respiration rate (24.5–59.0 ml CO2 kg−1 h−1), β-carotene (0.045–0.201 mg 100 g−1 FW) and lycopene content (0.08–0.244 mg 100 g−1 FW) was observed during storage, whereas there were a reduction in titratable acidity (0.162–0.075%), firmness (108–7.7 N) and hue angle (157–96.8°). ‘Frangi’ papaya particularly after 4 days of ambient storage showed improved antioxidant activity (0.32–1.55 mM Fe(II) g−1 FW).
