Abstract

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 (169-322mg100g-1 fresh weight (FW)), total phenolic content (0.515-0.686mgGAE (gallic acid equivalents) g-1FW), ethylene production (5.83-81.3μlkg-1h-1), respiration rate (24.5-59.0mlCO2kg-1h-1), β-carotene (0.045-0.201mg100g-1FW) and lycopene content (0.08-0.244mg100g-1FW) was observed during storage, whereas there were a reduction in titratable acidity (0.162-0.075%), firmness (108-7.7N) and hue angle (157-96.8°). 'Frangi' papaya particularly after 4 days of ambient storage showed improved antioxidant activity (0.32-1.55mMFe(II)g-1FW). © 2013 Elsevier B.V.
