Polyphenol microcapsule as well as preparation method and application thereof

The invention discloses a polyphenol microcapsule as well as a preparation method and application thereof, and belongs to the technical field of nano materials. The polyphenol microcapsule disclosed by the invention is prepared by emulsifying plant polyphenol serving as a core material and sodium alginate and chitosan serving as wall materials through an emulsifier. The plant polyphenol-sodium alginate/chitosan nano composite microcapsule prepared by the invention has high encapsulation efficiency and low particle size, not only improves the stability of the plant polyphenol and plays a slow release role, but also realizes effective improvement of the antioxidant and antiallergic effects of the plant polyphenol through synergistic interaction. 本发明公开了一种多酚微胶囊、其制备方法及应用，属于纳米材料技术领域。本发明的多酚微胶囊，是以植物多酚为芯材，以海藻酸钠和壳聚糖为壁材，经乳化剂乳化制备而成。本发明所制备的植物多酚-海藻酸钠/壳聚糖纳米复合微胶囊，具有高包封率和低粒径，不仅提高了植物多酚的稳定性，起到缓释作用，还通过协同增效来实现植物多酚抗氧化和抗过敏功效的有效提高。
