我们首次报告使用单分散的麦醇溶蛋白/壳聚糖混合颗粒作为颗粒乳化剂的皮克林高内相乳液（HIPES）的发展。在pH5.0时，采用一种简单的抗溶剂方法制备了具有部分润湿性的杂化粒子。内相含量高达83%的稳定Pickering HIPE可以在低颗粒浓度（0.5-2%）下制备。杂化胶乳能有效地吸附和锚定在油水界面上，对聚结产生空间位阻作用。同时，在Pickering HIPE中的压缩液滴形成一个膨胀的三维网络框架，赋予乳液粘弹性和自立的功能。Pickering HIPES对姜黄素有保护作用，且其初级氧化产物含量略低于原料油。这项工作开辟了一个有吸引力的战略，将液体油粘弹性软固体没有人工反式脂肪，作为一个潜在的替代PHO。(C)2017爱思唯尔有限公司版权所有
We report for the first time the usage of mono-dispersed gliadin/chitosan hybrid particles as a particulate emulsifier for Pickering high internal phase emulsions (HIPEs) development. The hybrid particles with partial wettability were fabricated at pH 5.0 using a facile anti-solvent route. Stable Pickering HIPEs with internal phases of up to 83% can be prepared with low particle concentrations (0.5-2%). The hybrid latexes were effectively adsorbed and anchored at the oil-water interface to exert steric hindrance against coalescence. Concomitantly, the compressed droplets in Pickering HIPEs to form a percolating 3D-network framework endowed the emulsions viscoelastic and self-standing features. The protective effect of Pickering HIPEs on curcumin was confirmed, and the content of primary oxidation products in HIPEs was slightly lower than that in bulk oil. This work opens an attractive strategy to convert liquid oils to viscoelastic soft solids without artificial trans fats, as a potential alternative for PHOs. (C) 2017 Elsevier Ltd.
