Today, there is an ever-growing interest on natural food ingredients both by consumers and producers in the food industry. In fact, people are looking for those products in the market which are free from artificial and synthetic additives and can promote their health. These food bioactive ingredients should be formulated in such a way that protects them against harsh process and environmental conditions and safely could be delivered to the target organs and cells. Nanoencapsulation is a perfect strategy for this situation and there have been many studies in recent years for nanoencapsulation of food components and nutraceuticals by different technologies. In this review paper, our main goal is firstly to have an overview of nanoencapsulation techniques applicable to food ingredients in a systematic classification, i.e., lipid-based nanocarriers, nature-inspired nanocarriers, special-equipment-based nanocarriers, biopolymer nanocarriers, and other miscellaneous nanocarriers. Then, application of these cutting-edge nanocarriers for different nutraceuticals including phenolic compounds and antioxidants, natural food colorants, antimicrobial agents and essential oils, vitamins, minerals, flavors, fish oils and essential fatty acids will be discussed along with presenting some examples in each field.

各种纳米载体对食品生物活性成分和保健食品的纳米封装的系统评价

如今，食品行业的消费者和生产者对天然食品成分的兴趣都与日俱增。实际上，人们正在市场上寻找不含人造和合成添加剂并能促进健康的产品。这些食品生物活性成分的配制应能保护它们免受恶劣的过程和环境条件的影响，并可以安全地输送到目标器官和细胞。纳米封装是解决这种情况的理想策略，近年来，已经有许多研究通过不同技术对食品成分和保健食品进行纳米封装。在这篇综述文件中，我们的主要目标是首先对适用于食品成分的纳米封装技术进行系统概述，即基于脂质的纳米载体，受自然启发的纳米载体，基于特殊设备的纳米载体，生物聚合物纳米载体和其他各种纳米载体。然后，将讨论这些尖端的纳米载体在不同营养品中的应用，包括酚类化合物和抗氧化剂，天然食用色素，抗菌剂和精油，维生素，矿物质，香料，鱼油和必需脂肪酸，并在每个实例中提供一些示例。场地。
