Special Considerations
Longan are fumigated with SO2 in Thailand and other
countries to prevent skin browning and to control postharvest
disease (Tongdee 1994). Although very effective,the treatment is not approved for use in the U.S. for fruit
to be sold as fresh. Asian consumers prefer longan in
bunches. They assume that single fruit have fallen from
the bunch because it has been dropped or that fruit are
not fresh. Individual fruit may also have a higher rate
of weight loss.
