| Abstract:
Future commercial success of Arazá industry in Colombian amazonic region depends on extending fruit life quality. 1 methylcyclopropene (1-MCP) has been successfully used for this purpose in our laboratory. To implement 1-MCP on a commercial scale, fruit were harvested in local orchards and treated with 1-MCP at 0 or 1 ppm for 1 h at 27°C, after which they were stored at two temperatures (13 or 27°C and 80±5% RH). The arazá fruit remained firm enough in both treatments during storage and shelf life periods of 10 and 4 d, respectively. The acidity and levels of organic acid composition in 1-MCP treated fruit was consistently higher than in untreated fruit irrespective of the storage temperature. The 1-MCP treatment reduced the respiration rate and ethylene production at 13°C and 80±5% RH. Consistently, 1-MCP also delayed the typical decrease in Hue angle associated in ripening for 10 d at the same conditions. Additionally, information about specific management of the 1-MCP treatment for this region is provided. In conclusion, the increase in fruit quality and shelf-life will encourage growers to produce arazá fruit for the fresh market and deliver it to the rest of the country. | |
