Longan ‘Huong Chi’ (Dimocarpus longan Lour.) is one of the most favorite and widely exported fruits in Vietnam, but the trading of longan faces considerable challenges due to rapid pericarp browning and decay. Our study aimed to determine the effects of modified atmospheres generated by low-density polyethylene (LDPE), polypropylene bag (PP), and LifeSpan L201 films on the quality and pericarp browning of ‘Huong Chi’ longan fruit pre-treated with 3.0 % citric acid and stored at 5oC. The results showed that LifeSpan L201 and LDPE packaging created an equilibrium atmosphere of 10.66 ± 0.78% O2, 4.44 ± 0.64% CO2, and 15.04 ± 0.89% O2, 2.96 ± 0.61% CO2,  respectively. The modified atmospheres generated by LifeSpan L201 and LDPE delayed pericarp browning, maintained the total soluble solids (TSS) and vitamin C content, and reduced decay in longan fruit. Meanwhile, the PP packaging resulted in an improperly modified atmosphere which led to severe decay and browning in cold storage conditions.
