Natural antimicrobial agents have been investigated as alternatives to synthetic ones for ensuring food safety and quality. However, the practical use of these preservatives in the food industry is limited due to their negative impact on the odor and taste of food products, as well as the early loss of functionality due to their rapid diffusion and interaction with food components. The incorporation of natural antimicrobial agents into edible coatings has been investigated to control diffusion of active compounds and maintain their concentrations at a critical level on a food surface. Recently, nanoencapsulating and multilayered/nanolaminate delivery systems have emerged as promising tools to enhance the functionality of edible coatings. This review highlights the potential use of polymeric edible coatings for the incorporation of natural antimicrobial agents and the improvement of their controlled release in food systems. The methods used to assess the antimicrobial activity of encapsulated natural antimicrobial agents and the most recent findings regarding the application of nanoencapsulating and multilayered/nanolaminate delivery systems in food products are also discussed.
天然抗菌剂已被作为合成抗菌剂的替代品进行研究，以确保食品安全和质量。然而，由于这些防腐剂对食品的气味和味道有负面影响，以及它们与食品成分快速扩散和相互作用导致功能过早丧失，它们在食品工业中的实际应用受到限制。将天然抗菌剂纳入可食用涂层已被研究，以控制活性化合物的扩散并将其浓度维持在食品表面的临界水平。最近，纳米包封和多层/纳米层状递送系统已成为增强可食用涂层功能的有前途的工具。本综述强调了聚合物可食用涂层在纳入天然抗菌剂以及改善其在食品系统中的控释方面的潜在用途。还讨论了用于评估包封天然抗菌剂抗菌活性的方法以及关于纳米包封和多层/纳米层状递送系统在食品中应用的最新发现。
