食品级皮克林乳液的稳定机制及稳定性研究进展

Advances in stabilization mechanism and stability control of food grade Pickering emulsion

本文综述了皮克林乳液的稳定机制,降解机制,稳定性调控以及皮克林乳液在食品行业的应用。皮克林乳液的稳定机制是通过胶体颗粒吸附在油水界面上,胶体颗粒形成固体网状结构以及形成较低程度的絮凝来稳定的。皮克林乳液的降解机制分为物理降解和化学降解,包括絮凝,聚集,沉淀,奥氏熟化以及脂质氧化等现象。现今常用来调控皮克林乳液稳定性的手段包括:粒子修饰,多种物质协同稳定,调节环境因素,调节粒子浓度等手段。本文旨在为研究皮克林乳液的稳定机制,降解机制以及在食品行业的应用提供一定的理论参考,从而扩大其在食品领域的应用范围。

The stability mechanism, degradation mechanism, stability regulation and the application of Picketing emulsion in food industry were reviewed in this paper.The stability mechanism of the Picketing emulsion is that the colloidal particles was adsorbed on the oil-water interface, the colloidal particles form a solid reticular structure and form a low degree of floccnlation. The degradation mechanism of Picketing emulsion was divided into physical degradation and chemical degradation, including flocculation, aggregation, sedimentation, Ostwald ripening and lipid oxidation. The methods commonly used to control the stability of Pickering emulsion include： particle modification, synergistic stabilization of various substances, regulating environmental factors and altering particle concentration.This article aims to provide some theoretical references for studying the stability mechanism, degradation mechanism and application of Pickering emulsion in the food industry, and to enlarge its application in the food field.
