Background

Molecular sieves are materials with selective sorption properties, and are used to separate or load mixtures of compounds based on their molecular shape and size. These materials are usually made from porous materials and molecularly imprinted polymers (MIPs).

Scope and approach

Although molecular matrices can be manufactured from either inorganic porous materials or MIPs, the former have been used more widely in the different fields of science and technology. Specifically, MIPs have been little studied as molecular sieves for food applications, as they have only very recently been introduced materials in this field. For this reason, in this review we focus on molecular sieves prepared from porous materials.

Key findings and conclusions

Molecular matrices have been mainly used as materials for food packaging, food nanoreactors, the absorption of pathogens, the controlled and sustained release of active compounds and enzymes, the stabilization and immobilization of active substances and enzymes, the detection and removal of food contaminants, and in the development of intelligent food contact materials. All these aspects are extensively reviewed in this manuscript, with particular emphasis on the literature published during the last five years.

食品用分子筛的综述

背景

分子筛是具有选择性吸附特性的材料，用于根据其分子形状和大小分离或负载化合物的混合物。这些材料通常由多孔材料和分子印迹聚合物（MIP）制成。

范围和方法

尽管分子基质可以用无机多孔材料或MIP制成，但前者已在科学和技术的不同领域中得到了更广泛的应用。具体地说，由于MIPs只是最近才被引入该领域，因此几乎没有作为食品应用的分子筛进行研究。因此，在本综述中，我们重点介绍由多孔材料制备的分子筛。

主要发现和结论

分子基质主要用作食品包装材料，食品纳米反应器，病原体吸收，活性化合物和酶的受控和持续释放，活性物质和酶的稳定和固定化，食品污染物的检测和去除以及开发智能食品接触材料。所有这些方面都在本手稿中进行了全面回顾，尤其着重于过去五年中发表的文献。
