To enhance the probiotics’ viability, novel vehicles consisting of synthetic/natural biopolymers, i.e., polyvinyl alcohol (PVOH), polyvinylpyrrolidone, whey protein concentrate and maltodextrin, encapsulated with L. plantarum KLDS 1.0328 and gum arabic (GA) as a prebiotic were fabricated by electrohydrodynamic techniques. Inclusion of cells into composites caused an increase in conductivity and viscosity. Morphological analysis showed that cells were distributed along the electrospun nanofibres or distributed randomly in the electrosprayed microcapsules. Both intramolecular and intermolecular hydrogen bond interactions exist between biopolymers and cells. Thermal analysis revealed that the degradation temperatures (>300 °C) of various encapsulation systems have potential applications in heat-treatment foods. Additionally, cells especially immobilized in PVOH/GA electrospun nanofibres showed the highest viability compared with free cells after exposure to simulated gastrointestinal stress. Furthermore, cells retained their antimicrobial ability after rehydration of the composite matrices. Therefore, electrohydrodynamic techniques have great potential in encapsulating probiotics.

为了提高益生菌的活力，由合成/天然生物聚合物组成的新型载体，即聚乙烯醇 (PVOH)、聚乙烯吡咯烷酮、乳清蛋白浓缩物和麦芽糖糊精，用植物乳杆菌包裹KLDS 1.0328 和阿拉伯树胶 (GA) 作为益生元是通过电流体动力学技术制备的。将细胞包含在复合材料中会导致电导率和粘度增加。形态学分析表明，细胞沿着电纺纳米纤维分布或随机分布在电喷雾微胶囊中。生物聚合物和细胞之间存在分子内和分子间氢键相互作用。热分析表明，各种封装系统的降解温度（> 300 °C）在热处理食品中具有潜在的应用。此外，与游离细胞相比，特别是固定在 PVOH/GA 电纺纳米纤维中的细胞在暴露于模拟胃肠道应激后显示出最高的活力。此外，复合基质再水化后，细胞保留了它们的抗菌能力。因此，电流体动力学技术在包封益生菌方面具有巨大潜力。
