摘　　要：探讨不同工艺条件下纳米SiOx粒子在水解胶原、海藻酸钠复合体系中的分散情况,在此基础上确定了水解胶原/海藻酸钠/纳米SiOx三元复合膜的制备工艺。实验进一步研究了纳米SiOx的加入量对复合膜力学性能、透水气性、抑菌性能的影响。结果表明,适量纳米SiOx可使复合膜抗张强度抑菌性能增加、透水气性减小,在食品保鲜领域具有一定的应用价值。The ratio of hydrolyzed collagen and sodium alginate solutions, dosage of dispersant and nano- SiOx, stirring strength and methods, ultrasonic disposal time were studied in this paper, on these basis, hydrolyzed collagen/sodium alginate/nano-SiOx complex film were prepared. Then the tensile strength, water vapor transmission and antibacterial ability of complex film were determined. The results showed that the tensile strength and antibacterial ability of the film were decreased however water vapor transmission increased after the addition of nano-SiOx, so this film can be used for the preservation of some foods.
