Abstract
The aim of this research was to evaluate the influence of 1-methylcyclopropene (1-MCP) and modified atmosphere packaging on the maturation of banana cultivar Prata harvested in the maturation stage 1. Banana hands were treated at room temperature with 0 and 60 ppb 1-MCP in sealed plastic chambers of 0.19 m3, during 24 hours.
Following the exposition to 1-MCP, a set of three fruits were packed in polystyrene trays and packed using XtendTM film (Stepac, L. A., Israel) for modified atmosphere generation and kept under ambient (AA) and modified atmospheres (MA) at 15°C and 90±2% of Relative Humidity and room temperature (23±2°C and 85±2% RH). At each evaluation period, three replications (1 set of three fruit/rep) from each treatment were used. 1-MCP application delayed the onset of respiratory peak, also maintained fruit gloss and retarded the increase in the a* and b* values, which is a result of the also delayed transition from the green to the yellow skin color.
However, the development of the skin yellow color was very irregular at 15°C storage.
On the other hand, 1-MCP treatment resulted in a more intense skin yellow color development for fruits kept at room temperature.
