研究了含有 ZnO 和银纳米颗粒的纳米复合低密度聚乙烯 (LDPE) 薄膜对莲藕 (NelumbonuciferaGaerth) 在 4 °C 下保存 12 天的影响。纳米填料不仅抑制了需氧菌的生长（<4 log cfu g−1），而且抑制了酵母菌和霉菌的生长，纳米填料中的最大生长量仅为3.3 log cfu g−1，而对照中的最大生长量为5.6 log cfu g−1。在含有纳米 ZnO 和纳米银颗粒的包装中观察到抗坏血酸 (AA) 降解最少 (39.2 mg/100 g) 和褐变率 (0.56)。纳米包装样品中的果实腐烂和丙二醛含量得到有效降低。结果表明，纳米氧化锌和纳米银镀膜作为替代非热技术可以将鲜切莲藕的保质期延长至9天。
The effect of nanocomposite low-density polyethylene (LDPE) films containing ZnO and silver nanoparticles on preservation of lotus root (NelumbonuciferaGaerth) store at 4 °C for 12 days was investigated. The nano-packing not only suppressed the growth of aerobic bacteria (<4 log cfu g−1), but also inhibited the increasing of yeast and molds, the maximum growth of which reached only 3.3 log cfu g−1 in the nano-packing while 5.6 log cfu g−1 in control. The least degradation of ascorbic acid (AA) (39.2 mg/100 g) and browning rate (0.56) were observed in package containing nano-ZnO and nanosilver particles. Fruit decay and MDA content were efficiently reduced in nano-packing samples. The results reveal that nano-ZnO and nanosilver coated film as an alternative non-thermal technology can extend the shelf life of fresh-cut lotus root up to 9 days.
