Abstract
- [Display omitted] • LBL emulsions including β-Car were encapsulated in vitreous encapsulated solids. • Polyelectrolyte shell composite by WPI/Arabic gum in LBL emulsions was 30 nm. • MD was a suitable carrier and good stabilizer to improve the stability of VES system. • Strength parameter can be linked to the stability and the β-Car loss of VES system. • Controlling of molecular mobility in wall materials slowed down β-Car degradation. β -Carotene (β - Car) is insoluble compounds in water and liable to degradation, which has health benefits for human beings. Although layer-by-layer (LBL) emulsions provide a better protection for β - Car towards environmental stresses, the handling and transportation of LBL emulsions still faces restrictions. In this paper, therefore, the LBL emulsions including β-Car were carefully prepared and encapsulated to obtain vitreous encapsulated solids (VES) using trehalose and maltodextrins (MD) as wall materials. Morphological results indicated that the LBL emulsions were formed a spheric shape, in where the polyelectrolyte shell was 30 nm. The MD exhibited the characteristics of not easy to absorb moisture, suitable carrier, and good stabilizer, which could improve the stability of VES systems at studied environmental stresses. Despite compositional effects from MD and environmental stresses, LBL emulsions changed the water sorption behavior of VES as oil dispersion in storage. Strength analysis indicated that LBL emulsions lubricated systems and increased the molecular mobility of wall materials. Structural collapse, rapid color changes, and β-Car loss were confirmed in VES systems at 0.56 a w from 25 to 45 °C after 30 days of storage. Besides, a relationship between S and β-Car loss kinetics was established, where the β-Car degraded more rapidly in a sample with quicker molecular mobility of wall materials Therefore, the controlling of molecular mobility in wall materials can slow down the β -Car degradation and improve the quality and stability of lipophilic nutrients delivery systems with high total solids.
