However, inadequate precooling and sulfur dioxide fumigation resulted in unexpected losses and short shelf life. A L<jats:sub>9<\/jats:sub>(3<jats:sup>4<\/jats:sup>) orthogonal test was conducted to screen out ideal dosage of sodium metabisulfite (factor A), precooling method (factor B), and precooling duration (factor C) to improve the storability of longan fruit stored for 48\u00a0hr at room temperature (RT) (25\u2103). The overall qualities of all of the treated longan fruits after a 48\u2010hr storage (OQST) and during the 5\u2010day shelf at 25\u2103 (OQSF) were better than those of the control fruits. The treated fruits showed brighter fresh color (higher L*, b*, C*, and h\u00b0 values but lower a* value), higher flavonoid, and chlorophyll contents. Moreover, the SO<jats:sub>2<\/jats:sub> residue was concentrated in pericarp but little in aril for any of the 12 treatments. The multivariate variance analysis showed that factor A was dominant to determine both of the OQST and OQSF, while factor B affected the OQST, and factor C affected the OQSF. In total, \u201c0.22% sodium metabisulfite\u00a0+\u00a04\u00a0hr precooling\u00a0+\u00a0uncovered precooling\u201d was considered to be an ideal treatment.
