In the food sector, one of the most important economic activities is the dairy industry, which has been facing many challenges in order to meet the increasing demand by consumers for natural and minimally processed products with high quality. In this sense, the application of innovative and emerging technologies can be an interesting alternative, for example, the use of nanotechnology in packaging and as delivery systems. This technology has the potential to improve the quality and safety of dairy products, representing an interesting approach for delivering food preservatives and improving the mechanical, barrier and functional properties of packaging. Several applications and promising results of nanostructures for dairy product preservation can be found throughout this review, including the use of metallic and polymeric nanoparticles, lipid-based nanostructures, nanofibers, nanofilms and nanocoatings. In addition, some relevant examples of the direct application of nanostructured natural antimicrobials in milk and cheese are presented and discussed, as well as the use of milk agar as a model for a preliminary test. Despite their high cost and the difficulties for scale-up, interesting results of these technologies in dairy foods and packaging materials have promoted a growing interest of the dairy industry.
在食品领域，最重要的经济活动之一是乳制品行业，为了满足消费者对天然且加工最少的高品质产品日益增长的需求，该行业一直面临诸多挑战。从这个意义上说，应用创新和新兴技术可能是一个有趣的选择，例如，在包装和作为递送系统中使用纳米技术。这项技术有潜力提高乳制品的质量和安全性，是一种递送食品防腐剂以及改善包装的机械、阻隔和功能特性的有趣方法。在这篇综述中可以找到纳米结构在乳制品保鲜方面的几种应用和有前景的结果，包括金属和聚合物纳米颗粒、脂质基纳米结构、纳米纤维、纳米薄膜和纳米涂层的使用。此外，还介绍并讨论了纳米结构天然抗菌剂在牛奶和奶酪中的直接应用的一些相关实例，以及使用牛奶琼脂作为初步测试模型的情况。尽管这些技术成本高昂且扩大规模存在困难，但它们在乳制品和包装材料方面取得的有趣成果激发了乳制品行业越来越浓厚的兴趣。
