Pickering乳液是指使用固体颗粒稳定的乳液,大多数用于稳定Pickering乳液的天然有机胶体颗粒的乳化性较差,需要采用一定的手段改性。目前,蛋白质基颗粒已被广泛应用于食品级Pickering乳液,而多糖基颗粒的研究相对较少。相比于单一多糖和多糖-多糖/蛋白颗粒,通过非共价或共价相互作用构建的多酚-多糖复合物颗粒不仅具有优良的乳化性,而且还能提高Pickering乳液的氧化稳定性,赋予其可调控的流变特性、广谱抗菌特性等。但是,有关于多酚-多糖复合物在食品级Pickering乳液中的应用鲜见系统的介绍。因此,本文在介绍Pickering乳液的稳定机理及多酚-多糖复合物的形成机制的基础上,综述了多酚-多糖复合物在食品级Pickering乳液中的应用,以期为多酚-多糖复合物在食品、药品、化妆品等领域中的应用提供参考。
