Postharvest behavior of Araza fruit treated with 1-MCP and stored at two temperatures

Araza Fruit harvested at green mature stage in Caqueta (Colombia) were treated with 0 (control in air) or 1000 ppb 1-MCP for 1 hour at 20°C and packed in macroperforated bags (liners) commonly required by UK supermarkets. Then fruit quality was inspected after 1 week at 7°C and 95% or at 12°C and 95% PH, with or without an additional shelf life period (3 days at 20°C and 70% RH). The goal of this project is to determine critical points associated to this treatment during postharvest handling from harvest to consumers in Colombia. 1-MCP delayed respiration rate, ethylene production and decrease in Hue angle colour parameter (around 8°) in green mature fruit compared with control fruit at 7°C and 12°C. Shrivelling and chilling injury in the form of skin scald were delayed by 1-MCP. Anthracnose development after the shelf-life period, was also delayed in treated fruits at both temperatures.

This short 1-MCP treatment was an useful coadjutant to extend shelf-life of green-mature araza fruit even when stored at suboptimum temperature.
