    摘要:

    皮克林乳液作为一种新型分散体系,是由微米级或纳米级的固体颗粒定向吸附于油水界面而形成的稳定系统。Pickering固体颗粒通常由淀粉、壳聚糖、蛋白质等有机化合物,以及二氧化硅、二氧化钛、碳酸钙等无机物加工得到。近年来,皮克林乳液的高效开发及其在食品领域的扩大应用,其稳定剂研究热点逐渐由无机态转向绿色安全且生物相容性良好的有机态固体颗粒。纳米淀粉颗粒(SNP)是以天然或改性淀粉为原料,由酸解、沉淀、研磨、超声等物理化学方法制得的纳米级尺度的有机颗粒,具有独特的纳米效应,以及来源广泛、可生物降解等优势。与传统乳化剂相比,SNP可在油水界面形成强有力的物理屏障,不易发生液滴聚结,在功能性营养物质的包埋和递送中具有更好的稳定性。基于此,本文综述纳米淀粉的制备方法和皮克林乳液的稳定机制,阐述纳米淀粉基皮克林乳液在食品领域的应用。

    Abstract:

    Pickering emulsion is a novel dispersion system, which can be stably formed via the directional adsorption of micron or nanoscale solid particles at the oil-water interface. The micron or nanoscale solid particles are usually composed of organic compounds such as starch, chitosan or protein, as well as inorganic substance such as silica, titania or calcium carbonate, etc. In recent years, due to the rapid development of Pickering emulsion and its extensive application in the food field, the research focuses more on the green, safe, and biocompatible organic material rather than inorganic counterparts. Among them, starch nanoparticles (SNP), which have unique nano-effects, wide range of sources, biodegradability and other advantages. Nano-scale organic particles are made from natural or modified starch, which are processed by physical and chemical methods such as acid hydrolysis, precipitation, grinding and ultrasonic. Compared with traditional emulsier, SNPs can form a powerful physical barrier at the oil-water interface, droplet coalescence is less prone to occur, and have better stability in the encapsulation and delivery of functional nutrients. Therefore, the preparation method of nanostarch and the stabilization mechanism of Pickering emulsion were reviewed in this paper. The application of nanostarch-based Pickering emulsion in food field were elucidated.
