壳聚糖是从甲壳动物废弃物中获得的有价值的产品之一。壳聚糖的独特特性（抗菌、抗氧化、抗癌和抗炎）增加了它在各个领域的应用。除了独特的生物学特性，壳聚糖或基于壳聚糖的化合物可以稳定乳化液。然而，研究表明，由于壳聚糖的高亲水性，它不能用作有效的稳定剂。因此，本综述旨在提供关于改善壳聚糖乳化特性的最新研究概述。通常，改进壳聚糖乳化特性有两种不同的方法。第一种方法试图通过改变壳聚糖的结构来改善其稳定性。第二种方法使用大分子多糖、蛋白质、表面活性剂、精油和多酚等具有比壳聚糖粒子更好的润湿性和乳化特性的化合物与壳聚糖结合以创建复合粒子。最近，使用基于壳聚糖的粒子稳定 Pickering 乳液的趋势有所增加。因此，近年来进行了更多的研究，以改善基于壳聚糖的粒子的稳定特性，特别是使用静电相互作用方法。在静电相互作用方法中，已经进行了大量的研究，试图使用蛋白质和多糖来增加壳聚糖的稳定性能。版权所有©2023 Elsevier B.V. 出版。

Chitosan is one of the valuable products obtained from crustacean waste. The unique characteristics of chitosan (antimicrobial, antioxidant, anticancer, and anti-inflammatory) have increased its application in various sectors. Besides unique biological properties, chitosan or chitosan-based compounds can stabilize emulsions. Nevertheless, studies have shown that chitosan cannot be used as an efficient stabilizer because of its high hydrophilicity. Hence, this review aims to provide an overview of recent studies dealing with improving the emulsifying properties of chitosan. In general, two different approaches have been reported to improve the emulsifying properties of chitosan. The first approach tries to improve the stabilization property of chitosan by modifying its structure. The second one uses compounds such as polysaccharides, proteins, surfactants, essential oils, and polyphenols with more wettability and emulsifying properties than chitosan's particles in combination with chitosan to create complex particles. The tendency to use chitosan-based particles to stabilize Pickering emulsions has recently increased. For this reason, more studies have been conducted in recent years to improve the stabilizing properties of chitosan-based particles, especially using the electrostatic interaction method. In the electrostatic interaction method, numerous research has been conducted on using proteins and polysaccharides to increase the stabilizing property of chitosan.Copyright © 2023.
