基于天然生物大分子的高内相乳液及其在食品中的应用

High Internal Phase Emulsions Based on Natural Biomacromolecules and Their Application in Foods

高内相乳液具有高黏弹性、高稳定性以及优良的质地等特性,这推动了其在食品、医疗、材料和化妆品领域的广泛探索和应用。天然生物大分子具有安全、环保和生物相容性等特点,被广泛用于稳定高内相乳液。文章对近年来天然生物大分子稳定高内相乳液的制备方法、乳化剂类型以及在封装和递送营养物质、包埋益生菌、作为饱和脂肪酸和反式脂肪酸的替代品、3D打印和制备多孔材料等食品领域的应用进行了综述,并对未来的研究方向进行了展望,为后续深入研究奠定了理论基础,以期推动在食品中的进一步开发和应用。

High internal phase emulsions(HIPEs)are characterized by high viscoelasticity,high stability,and excellent texture,which has driven their extensive exploration and application in the fields of food,medicine,materials,and cosmetics.Natural biomacromolecules are widely used to stabilize HIPEs because of their safety,environmental friendliness and biocompatibility.This paper reviewed the preparation methods of stabilized HIPEs of natural biomacromolecules,types of emulsifiers,and their applications in food fields such as encapsulation and delivery of nutrients,embedding of probiotics,as substitutes for saturated fatty acids and trans-fatty acids,3D printing and preparation of porous materials in recent years,and provided an outlook on the future direction of the research,laying a theoretical foundation for the subsequent in-depth research,with aim of promoting further development and application in food.
