摘　　要：为弥补琼脂基抗菌包装膜研究空白,将不同浓度Nisin(乳酸链球菌素)加入琼脂中,采用流延法制备出一种新型抗菌包装膜,并对抗菌膜抑菌性和膜性能指标进行了测试。结果表明:随抗菌剂添加量的增加,厚度、抑菌活性、雾度、阻隔性、断裂伸长率均呈上升趋势,而透光率、色泽、抗拉强度则明显下降,且在不同湿度条件下对膜的机械性能也存在一定影响。对琼脂基抗菌膜进行了讨论与展望,为工业化生产提供依据。In order to make up the research blank of agar based antibacterial packaging film,Nisin with different concentrations was added to agar,a new type of antibacterial packaging film was prepared by casting method,and the bacteriostasis and membrane performance of were tested.The results showed that with the increase of the amount of antibacterial agents,the thickness,the bacteriostasis activity,the fog,the barrier and the elongation at break all increased,while the transmittance,color and tensile strength decreased obviously,and the mechanical properties of the membranes were also affected under different humidity conditions.The agar based antibacterial film was discussed to provide the basis for industrial production.
