A new era is rising in food packaging and preservation, with a consequent focus on transition to "greener" and environmentally friendly techniques. The environmental problems that are emerging nowadays impose use of natural materials for food packaging applications, replacement of chemical preservatives with natural organic extractions, such as essential oils, and targeting of new achievements, such as further extension of food shelf-life. According to this new philosophy, most of the used materials for food packaging should be recyclable, natural or bio-based, and/or edible. The aim of this work was to investigate use and efficiency of a novel food packaging developed based on commercial LDPE polymer incorporated with natural material halloysite impregnated with natural extract of thyme oil. Moreover, a direct correlation between the stiff TBARS method and the easiest heme iron measurements method was scanned to test food lesions easier and faster. The result of this study was development of the LDPE/10TO@HNT film, which contains the optimum amount of a hybrid nanostructure and is capable to be used as an efficient active food packaging film. Furthermore, a linear correlation seems to connect the TBARS and heme iron measurements.
食品包装与保鲜领域正在迎来一个新时代,随之而来的是对向“更绿色”和环保技术转型的关注。当前出现的环境问题促使在食品包装应用中使用天然材料,用天然有机提取物(如精油)替代化学防腐剂,并致力于取得新成果,如进一步延长食品保质期。按照这种新理念,大多数用于食品包装的材料应是可回收的、天然的或生物基的,和/或可食用的。这项工作的目的是研究一种新型食品包装的使用情况和效率,该包装基于商业低密度聚乙烯(LDPE)聚合物开发,其中掺入了浸渍有百里香油天然提取物的天然材料埃洛石。此外,研究了僵化的硫代巴比妥酸反应物(TBARS)方法与最简单的血红素铁测量方法之间的直接关联,以便更轻松、快速地检测食品损伤情况。本研究的结果是开发出了LDPE/10TO@HNT薄膜,其含有最佳量的混合纳米结构,能够用作高效的活性食品包装薄膜。此外,TBARS与血红素铁测量之间似乎存在线性关联。
