The postharvest Litchi (Litchi chinensis Sonn.) fruit was treated with colour protective agent composed of 1% citric acid and 3% NaCl and stored in modified atmosphere (5%CO2/5%O2/90%N2) at (4±1)°C. The anthocycanin, moisture content and the browning index of the pericarp were investigated as factors responsible for the decline of the exterior quality, while the soluble solid content, titratable acidity and the ascorbic acid content of pulp were measured as factors responsible for the decline of the interior quality. The results showed that both the exterior quality and interior quality of Litchi fruit with postharvest treatments were better than that without any treatments. The shelf life of the samples which were dipped in the colour protective agent and packaged in modified atmosphere bags could prolong to 39 days. The good fruit rate was more than 90% with the browning index 1.52.
