The edible complex films formed from high-amylose cornstarch(HACS),chitosan(CS) and methyl cellulose(MC) were prepared.The properties of films with mass ratio of HACS/CS 1∶ 0,2∶ 1,1∶ 1,1∶ 2,0∶ 1 and cellulose(MC) content of 0%,2%,4%,6%,8% were analyzed.Three complex films were used in the storage experiment of garden pea(Pisum.sativum.L.).The mass ratio was HACS/CS 2∶ 1,1∶ 1 and 1∶ 2(8% MC added simultaneously),respectively.The results showed that rates of weight-loss and mildewing were effectively reduced,the loss of chlorophyll and vitamin C were also delayed.Among three of them,complex film composed by HACS/CS with ratio of 2∶ 1 exhibited the best preservation effect.
