Abstract This paper produced stable Pickering emulsions by using fibrous chitin nanofibers (ChNFs) and spherical zein colloid particles (ZCPs) complex as stabilizer. Transmission electronic microscopy showed that some ZCPs linked onto ChNFs chains but no entanglement. The main driving force between ChNFs and ZCPs might be hydrogen bond and hydrophobic interaction. ChNFs-stabilized Pickering emulsions had smaller particle size and better distribution than ZCPs-stabilized ones. Results from confocal laser scanning microscopy (CLSM) proved that both of them could adsorb on the oil/water interface as Pickering stabilizer. ChNFs aggregations were found on the oil/water interface, providing steric hindrance among oil droplets. When fixing ChNFs content, ChNFs/ZCPs complex-stabilized Pickering emulsions had larger particle size at low ZCPs content and smaller particle size at high ZCPs content. As compared to ZCPs-stabilized emulsions, they exhibited smaller particle size and higher centrifuge stability, especially at the ZCPs: ChNFs ratio more than 5 g g −1 . The CLSM proved that ZCPs altering the accumulation of ChNFs on the oil/water interface. Therefore, regulating the interaction between ZCPs and ChNFs is an effective means to regulate the physicochemical properties of emulsions.

原始几丁质纳米纤维和玉米蛋白胶体颗粒的复合物作为稳定剂用于生产稳定的pickering乳液

摘要 本文以纤维状几丁质纳米纤维（ChNFs）和球形玉米醇溶蛋白胶体颗粒（ZCPs）复合物为稳定剂，制备了稳定的Pickering乳液。透射电子显微镜显示一些 ZCPs 连接到 ChNFs 链但没有纠缠。ChNFs 和 ZCPs 之间的主要驱动力可能是氢键和疏水相互作用。ChNFs 稳定的 Pickering 乳液比 ZCPs 稳定的乳液具有更小的粒径和更好的分布。共聚焦激光扫描显微镜 (CLSM) 的结果证明，它们都可以作为 Pickering 稳定剂吸附在油/水界面上。在油/水界面上发现了 ChNFs 聚集体，在油滴之间提供了空间位阻。在修复 ChNFs 内容时，ChNFs/ZCPs 复合稳定的 Pickering 乳液在低 ZCPs 含量下具有较大的粒径，在高 ZCPs 含量下具有较小的粒径。与 ZCPs 稳定的乳液相比，它们表现出更小的粒径和更高的离心机稳定性，尤其是在 ZCPs:ChNFs 比率超过 5 g g -1 时。CLSM 证明 ZCP 改变了 ChNF 在油/水界面上的积累。因此，调节ZCPs与ChNFs之间的相互作用是调节乳液理化性质的有效手段。
