| 摘 要： | 以高直链玉米淀粉(HACS)、壳聚糖(CS)和甲基纤维素(MC)为原料制备可食性复合膜,研究了HACS/CS质量配比分别为1∶0、2∶1、1∶1、1∶2及0∶1,MC添加量(占干基淀粉)分别为0%、2%、4%、6%及8%时的成膜性能,并从中选取HACS/CS质量比为2∶1、1∶2、1∶1添加8%MC的3种膜进行荷兰豆保鲜实验。结果表明:3种膜均能有效降低荷兰豆的失重率和霉变率,减缓叶绿素和Vc的损失。其中,质量比HACS/CS为2∶1的膜,综合保鲜效果最好。

| Abstract: | 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. |
