Effects of different wall materials on the physicochemical properties and oxidative stability of spray-dried microencapsulated red-fleshed Pitaya (Hylocereus polyrhizus) seed oil.

The aim of this research was to investigate the influence of the composition of the wall material on the encapsulation and stability of microencapsulated red-fleshed pitaya seed oil. Hylocereus polyrhizus seed oil was homogenized with various wall material solutions at a core/wall material ratio of...
