Hybrid electrospinning of pullulan and citrus pectin to load astaxanthin: Preparation, characterization, and functional evaluation.

Pullulan (PUL) is a widely used agent for electrospinning. However, nanofibers electrospun solely from PUL exhibit a highly hydrophilic nature and a bead-like structure. In this study, 1-5 wt% citrus pectin (CP) was introduced to construct a hybrid electrospinning system to investigate the effects of CP concentration on the properties of the electrospun nanofibers.
