摘要

In this study, a multi-response optimization was applied to determine the optimal postharvest treatment factors for Vietnamese longan 'Huong Chi' throughout the whole storage period. Instrumental measurements were used to analyze quality attributes including soluble solids content, total acidity, weight loss, pericarp color, total phenolics, pericarp browning and microbial disease of the fruit at harvest and after 10, 20, 30, and 37 d of storage. The optimal postharvest treatment for export fruit, in which no fungicide residue is allowed, consisted of dipping the fruit for 10 min in a 7 mM oxalic acid solution and draining them. For fruit for the local market, the optimal treatment consisted of dipping the fruit for 1 min in a 0.06% solution of carbendazim, followed by a 10min dip in a 6.5 mM oxalic acid solution and finally draining. In both cases, fruit should be packed in a polypropylene bag with a relative perforation area of 0.01% and stored at 4 +/- 1 degrees C. The overall quality of Iongan fruit could thus be maintained for 37 d of storage.
