This project was initiated to develop a post harvest handling strategy for Longan suitable for both export and domestic marketing. Little information exists on optimum storage temperatures, packaging and humidity for the most commonly grown longan varieties in Australia. Also much of the industry relies on SO2 fumigation for post harvest handling. While SO2 works very well there are health and safety concerns about its use, which may see its removal. At the Australian longan industry strategic review and priority workshop improved post harvest handling skills and an investigation of alternative strategies to SO2 were seen as high priority.
The project results provide information, which is currently lacking – optimal storage temperature and humidity for the Australian grown varieties as well as an alternative treatment to SO2, which can be used to extend the shelf life.
