Potato protein particles and fibers were produced using electrohydrodynamic processing (electrospray and electrospinning). The effect of different solvents and protein concentration on the morphology of the potato protein particles and fibers was investigated. Electrosprayed particles with average diameters ranging from 0.3 to 1.4 µm could be obtained using water and mixtures of water: ethanol (9:1) and water:glycerol (9:1). Electrosprayed particles were also obtained using the solvent hexafluoro-2-propanol (HFIP) at a protein concentration of 5% /. For protein concentrations above 10% /, using HFIP, electrospun fibers were produced. The release of vitamin B12, as a model bioactive compound, from potato protein electrospun fibers, was also investigated, demonstrating their potential to be utilized as encapsulation and delivery systems.
采用静电纺丝（电喷雾和静电纺丝）技术制备马铃薯蛋白颗粒和纤维。研究了不同溶剂和蛋白质浓度对马铃薯蛋白颗粒和纤维形态的影响。使用水和水：乙醇（9:1）和水：甘油（9:1）的混合物可以获得平均直径在 0.3 至 1.4 µm 之间的电喷雾颗粒。在 5%/的蛋白质浓度下，也可以使用六氟异丙醇（HFIP）作为溶剂获得电喷雾颗粒。对于浓度高于 10%/的蛋白质，使用 HFIP 可以制备出电纺纤维。还研究了维生素 B12（作为模型生物活性化合物）从马铃薯蛋白电纺纤维中的释放情况，表明它们有可能作为封装和输送系统。
