Sažetak
Glucosyl-hesperidin is a water soluble derivate of hesperidin. Both these derivates have many health- promoting properties such as antioxidant, anti- inflammatory and antimicrobial activities. However, the low water solubility of hesperidin disables its wide utilization in the food and pharmaceutical industries so glucosyl-hesperidin has an advantage concerning new product development. The aim of the study was to produce hydrogel beads filled with glucosyl-hesperidin by applying microencapsulation technique using vibration technology. Beads were fabricated under the same operating conditions of the encapsulator and obtained by dropping a mixture of glucosyl- hesperidin and alginate into different hardening solutions (calcium chloride or calcium chloride- chitosan) with different times of complexation (30 min or 90 min). The highest retention ability of glucosyl-hesperidin had chitosan-alginate beads, which were complexed for 30 min (590.93 mg/kg), while the lowest retention ability was observed for alginate beads with a complexation time of 30 min (409.94 mg/kg). Beads were stored for 7 days at ambient temperature and in the presence of light. The highest amount of glucosyl-hesperidin was detected in chitosan-alginate beads as after preparation. Results of this study give insight into glucosyl-hesperidin encapsulation into hydrogel beads and its behavior during storage.
