Low density polyethylene (LDPE) based nanocomposite films made from different levels of nanoclay, compatibilizer and thickness were evaluated for the storage stability of sugarcane juice for 60 days under ambient condition. During the storage period, important physico-chemical properties such as pH, total sugars, total soluble solids and overall acceptability were decreased with respect to increased level of nanoclay and compatibilizer as well as decreased thickness of film. Total plate count was nil till the storage period of 15 days and then there was an increase in microbial population. Similarly, the overall color difference was also increased during the storage period. The better storage stability with respect to biochemical characteristics, overall acceptability and microbial load was recorded in the 100 µm thick LDPE nano composite films developed from 93 percent LDPE, 2 percent nanoclay and 5 percent compatibilizer.
对由不同含量的纳米粘土、增容剂和厚度制成的低密度聚乙烯（LDPE）基纳米复合薄膜，在环境条件下对甘蔗汁进行60天的储存稳定性评估。在储存期间，随着纳米粘土和增容剂含量的增加以及薄膜厚度的减小，诸如pH值、总糖、总可溶性固形物和总体可接受性等重要的物理化学性质均有所下降。在储存15天之前，总平板计数为零，之后微生物数量增加。同样，在储存期间总体色差也有所增加。由93%的LDPE、2%的纳米粘土和5%的增容剂制成的100微米厚的LDPE纳米复合薄膜，在生化特性、总体可接受性和微生物负荷方面具有更好的储存稳定性。
