Broccoli raab florets were treated with 1LL−1 of 1-MCP for 24 h at 20 ◦C and then stored, together
with the untreated control, at 5 ◦C for 14 days in a humidified air flow and air + 100LL−1 of ethylene.
Treatment with 1-MCP markedly extended the shelf life, reducing postharvest deterioration, retarding
chlorophyll degradation, and delaying visual quality loss and flowering, as was also the case with samples
stored in the presence of exogenous ethylene. Untreated broccoli raab florets stored either in air or
in air + ethylene showed a significant increase in ammonia during storage, suggesting stressful storage
conditions. These results indicate that a 1-MCP treatment could be a good candidate for extending shelf
life, maintaining visual quality and reducing loss of quality in broccoli raab florets.
