The effect of the new anti-ethylene compound 1-methylcyclopropene (1-MCP) in
combination with polyethylene bags on the ripening of harvested banana fruit
was investigated. 1-MCP treatment delayed peel colour change and fruit
softening, and extended shelf life in association with suppression of
respiration and C2H4 evolution. Banana fruit ripening was
delayed when exposed to 0.01¯1.0 
l
1-MCP/l for 24 h, and increasing concentrations of 1-MCP were generally more
effective for longer periods of time. Similar results were obtained with fruit
sealed in polyethylene bags (0.03 mm thick) containing 1-MCP at various
concentrations, but longer delays in ripening were achieved. The greatest
longevity of about 58 days was realised by packing fruit in sealed polyethylene
bags with 1-MCP at either of 0.5 or 1.0 l/l.
Analyses of C2H4 and CO2 concentrations within
polyethylene bags confirmed that 1-MCP suppressed both C2H4
evolution and respiration. Thus, application of 1-MCP in combination with the
use of polyethylene bags can greatly extend the postharvest life of banana
fruit.
