Abstract : To prolong the preservation stage of mango, the fresh mango fruit was used as experimental materials to study the effects of chitosan quaternary ammonium salt coating on mango storage. The results showed that mango was stable for 18 days at room temperature (26-30°C) when quaternary ammonium salt of chitosan solution concentration was 0.50%, pH was 5.50 and soaking time was 150 s. The weight loss ratio was 1.80%-3.07% and the soluble solids content was 17.8%-22.7%. The application of chitosan quaternary ammonium salt coating effectively slowed down the losses of water and soluble solids, achieving the purpose of extending the shelf life and improving the quality.
