摘　　要：利用壳聚糖膜在果蔬上的保鲜效果,并通过纳米纤维素对壳聚糖膜在性能上的加强,以求制得保鲜效果更好的膜。本研究首先以糠醛渣为原料制备了纳米纤维素,然后分别以2%的壳聚糖+1.5%的醋酸溶液+(0~10%)的纳米纤维素制得纳米纤维素-壳聚糖复合膜。发现在机械强度上,纳米纤维素含量为4%的复合膜性质最好,并随着纳米纤维素含量的增加,复合膜吸水性,透湿性以及断裂伸长率都逐渐的有所降低。The effect of chitosan on fruit and vegetable preservation and nano- cellulose on properties of chitosan membrane in the reinforcement can make a better film. Nano-cellulose was prepared from furfural residue,and then nano-cellulose- chitosan complex film was made adding 2% ＋ 1. 5% of chitosan acetic acid solution（ 0 ~ 10%） of nano-cellulose. Test results showed that on mechanical strength,composite membrane properties of nano-cellulose content of4% was best,and with increase of nano-cellulose content,composite membrane water absorption,moisture penetration and elongation gradually decreased.
