The first aim of present work was to investigate the effects of a semi-commercial postharvest treatment with 1-MCP on the quality of Pink Lady apples as functions of fruit ripening stage, 1-MCP dose and storage time. The second aim of this study was to evaluate the effect of 1-MCP treatment carried out on fresh pineapples and MAP of their fresh cut products with an alternative modified atmosphere (86.13 kPa N2O, 10.13 O2, and 5.07 kPa CO2) on the physiological and quality changes of minimally processed pineapple during refrigerated storage. The results showed that 1-MCP treatment and MAP in a N2O enriched atmosphere had a positive effect on the inhibition of respiration and ethylene production. From a microbiological viewpoint, N2O MAP extended the shelf-life of the products of 3-4 days by increasing the lag phase of microbial growth.
