塑料已成功地用作包装材料，但环境问题的增加导致对替代生物相容性材料的兴趣越来越大。应用于食品包装领域的生物纳米复合材料的开发是纳米研究的一个主要新兴领域。包封可以使用诸如喷雾干燥、喷雾冷却和激冷、流化床包衣、凝聚、脂质体包埋、共结晶、纳米乳液、空气悬浮、冷冻干燥、界面聚合、分子包合和溶胶-凝胶的程序进行。基于脂质的纳米结构如脂质体和固体脂质纳米颗粒用于递送显示抗微生物和抗氧化活性的生物活性分子。脂溶性维生素可以掺入纳米乳液中，加入聚合物纳米颗粒中，是植物化学物质如槲皮素和姜黄素的合适载体。纳米纤维也可用于将生物活性物质纳入食品包装中。本章介绍了将生物活性化合物封装到纳米结构中的方法，然后可以将其纳入包装材料中，以提高食品质量和安全性。
Plastics have been successfully used as packaging materials, but increased environmental concerns lead to a growing interest on alternative biocompatible materials. The development of bionanocomposites for application in the food packaging sector is a major emergent fields in nano-research. Encapsulation can be done using procedures such as spray drying, spray cooling and chilling, fluidized bed coating, coacervation, liposome entrapment, co-crystallization, nanoemulsion, air suspension, freeze-drying, interfacial polymerization, molecular inclusion and sol-gel. Lipid-based nanostructures such as liposomes and solid-lipid nanoparticles are used for the delivery of bioactive molecules showing antimicrobial and antioxidant activities. Fat-soluble vitamins can be incorporated in nanoemulsions, which, added to polymeric nanoparticles, are suitable vehicles to phytochemicals like quercitin and curcumin. Nanofibers can also be used to incorporate bioactive substances in food packaging. This chapter presents methods for encapsulation of bioactive compounds into nanostructures, which can then be incorporated into packaging materials to improve food quality and safety.
