Methyl jasmonate and modified atmosphere packaging (MAP) reduce decay and maintain postharvest quality of papaya ‘Sunrise’

Exposure of papaya (Carica papaya L., cv. Sunrise) fruitto methyl jasmonate (MJ) vapors (10-5 or 10-4 M) for 16 h at 20 °C inhibited fungal decay and reducedchilling injurydevelopment and loss of firmness during storage for 14–32 days at 10 °C and 4 days shelf life at 20 °C. MJ-treatedfruitalso retained higher organic acids than the controlfruit.Low density polyethylene film packaging prevented water loss and further loss of firmness as well as inhibiting yellowing (b* values) of papaya fruit.The modified atmosphere created (3–5 kPa O2 and 6–9 kPa CO2) inside the package did not induce any off-flavor development during storage at 10 °C. The postharvest quality of papaya was enhanced significantly by combining the MJ-treatments and MAP. Use of MJ at 10-5 M with MAP is beneficial to maintaining postharvest quality of papaya during low temperature storage and shelf-life period.
