Abstract

Background: The clay Montmorillonite (MMT) is among the nanofillers more frequently used in food packaging. The uniform dispersion of nanoparticles in polymers confers considerable improvement of mechanical, thermal, optical, and/or barrier properties in polymer/clay nanocomposites.

Objective: The aim is to ascertain the state of the art of the use of MMT for packaging purposes, with special emphasis on food applications.

Methods: A literature review was carried out through recent papers and patents that focused on the incorporation of MMT in polymers.

Results: This review emphasizes the interaction of MMT with polymers and their levels of incorporation in the nanocomposites. This work also highlights the analytical methodologies used for the characterization of the polymer/clay nanocomposites and the main consequences of the fillers in the properties of nanocomposites. Challenges remain about increasing the compatibility between clays and biopolymers to promote their utilization in food packaging. New strategies for immobilization of oxides, enzymes, essential oils, and other bioactive compounds are needed.

Conclusion: MMT-based composite materials are promising to be used in intelligent and active packaging.

蒙脱土在食品纳米复合材料中的应用:蒙脱土/聚合物纳米复合材料的掺入方法、表征及其性能的主要影响。
背景:粘土蒙脱土(MMT)是食品包装中最常用的纳米填料之一。纳米粒子在聚合物中的均匀分散使聚合物/粘土纳米复合材料的机械、热、光学和/或阻隔性能得到了显著改善。目的:目的是确定使用MMT包装目的,特别强调食品应用的艺术状态。方法:通过最近的论文和专利进行了文献综述,重点是在聚合物中掺入MMT。结果:本综述强调了MMT与聚合物的相互作用及其在纳米复合材料中的掺入水平。这项工作还强调了用于表征聚合物/粘土纳米复合材料的分析方法,以及填料对纳米复合材料性能的主要影响。如何提高粘土和生物聚合物之间的相容性以促进其在食品包装中的应用仍是一个挑战。需要新的固定氧化物、酶、精油和其他生物活性化合物的策略。结论:mmt基复合材料在智能、活性包装领域具有广阔的应用前景。
