Litchi fruit were soaked for 2 min in a solution of 0.1% N-Acetyl Cysteine (AC) +1% Isoascorbic Acid (IAA) and held for 7 days at 25 C and 80-90% relative humidity for quality assessments. Use of AC and IAA combination significantly reduced fruit decay and browning, markedly inhibited polyphenol oxidase activity and maintained higher level of anthocyanin in pericarp tissues. Fruit treated with 0.1% AC +1% IAA had good visual appearance. The use of the combination of 0.1% AC +1% IAA could be considered for commercial application in inhibiting pericarp browning and maintaining flesh quality of litchi fruit during storage.
