Abstract
This study aimed to evaluate hydrogel properties produced by electrospraying alginate/AHSG (Alyssum homolocarpum seed gum) dispersions at different mixing ratios (0:100, 25:75, 50:50, 75:25, and 100:0). The results revealed that the ζ-potential and electrical conductivity of dispersions decreased with increasing the alginate to AHSG ratio. The dispersions were able to be atomized from the tip of the nozzle without the need for surfactant addition. The apparent viscosity increased with increasing alginate to AHSG ratio. The size of particles decreased, and their sphericity increased when the alginate to AHSG ratio increased. Intermolecular hydrogen bonds were formed between alginate and AHSG. The thermal stability of hydrogel increased as the alginate to AHSG ratio increased. At a mixing ratio of 75 alginate:25 AHSG, the porous structure of alginate hydrogel beads reduced. The XRD spectrum indicated that the crystalline structure of gums transformed into the amorphous state after the electrospraying.
