Abstract

      Longan (Dimocarpus longan) fruit is one of the most popular fruits in Viet Nam. However, postharvest pericarp browning and rapid decay limit the postharvest life of longan fruit. In the present study, the effect of different postharvest treatments on fruit quality was investigated. The incidence of microbial disease, browning index, weight loss, polyphenol content and other nutrional quality attributes were determined at harvest and 10, 20, 30, 35 days after storage. Results suggested that pericarp browning, microbial disease, and fruit quality deterioration could be better delayed compared to the control at 35 days after storage by dipping fruits in carbendazim 0.1%, followed by oxalic acid 4 mM, finally packed in polypropylene bag with 0.008% of relative perforation area and stored at 4 ±1oC and relative humidity of 95%.
