Résumé

Exposure of papaya (Carica papaya L., cv. Sunrise) fruit to methyl jasmonate (MJ) vapours for 16 h at 20 °C inhibited fungal decay and reduced chilling injury development and loss of firmness during storage for 14-32 days at 10 °C and 4 days shelf life at 20 °C. MJ-treated fruit also retained higher organic acids than the controls. 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 inside the package did not induce any off-flavour 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 1 million M with MAP is beneficial for maintaining postharvest quality of papaya during low-temperature storage and shelf-life period.
