| Abstract:
'Tommy Atkins' mangoes were harvested at stage 2 maturity and treated in a day later with 1-methylcyclopropene (SmartFresh™, 100 and 500 nL.L-1), at room temperature for 12 hours. Some fruits were wrapped with Xtend™, for modified atmosphere generation and the effects of 1-MCP and modified atmosphere (with or without MA) were evaluated during 25 days of storage at 11.5 ± 1.7 °C and 86.1 ± 8.4 % RH, followed by 7 days at 25.4 ± 0.2 °C and 97.6 ± 1.2 % RH. Sensory analysis was carried out once, after storage. Luminosity (*L) measured in the green part of the mango skin was affected by 1-MCP doses until the 25th day, and values were higher in fruits stored without MA. Effects of were only noticed in *L and Chroma (C) characteristics of pulp color. *L values were lower and C values were higher when MA was used. Modified atmosphere was efficient in protecting fruits from weight loss during cold storage. Fruits stored without MA and treated with 100 nL.L-1 were firmer but this was not detected by the sensory panel. Sensory analysis revealed that ripening was accelerated for fruits stored under MA and for those treated with 500 nL.L-1 and kept without MA. Judges did not notice differences in aroma, color or firmness between the control and 100 nL.L-1 treated fruits. | |
