What is it about?
An alternative to SO2 fumigation strategy was designed for longan fruit. An optimum controlled atmosphere was developed based on the tolerance levels of longan fruit to various low levels of O2 and elevated CO2.

Why is it important?
Pericarp browning and microbial decay are the major concerns which have limited the postharvest life of longan fruits. SO2 fumigation, an inexpensive and convenient way widely been used to prevent pericarp browning and decay of longan. However, due to safety concern of SO2 to public health, an optimum controlled atmosphere as an alternative to SO2 fumigation, was proposed which extended the postharvest life of longan to 35 days at 5 C.
Perspectives
This is the first article that designed an optimum controlled atmosphere based on the tolerance levels of the produce to various levels of O2 and CO2, which also have provided a new window for the designing modified atmosphere packaging of longan fruit.
