Konjac glucomannan complex film solution,carboxymethyl chitosan film solution and starch film solution were used to coat pomelo fruit（Guanxi Honey Pomelo）.The coated fruit were storaged at room temperature,and their physiological and biochemical parameters were determined,such as pulp organic acids,respiration rate,ethanol concentration,weight loss,catalase activity,etc.The results showed that the coated fruit were lower in all the parameters determined than the control,and that the coatings effectively extended the shelf life of the pomelo fruit.The pomelo fruit had a shelf life of upto 80 days when coated with starch film solution,upto 90 days when coated with the carboxymethyl chitosan film solution,and upto 120 days when coated with the konjac glucomannan complex film solution.
