Popis: | This study aimed to evaluate the possibility of using gum arabic (GA) with different protein materials namely whey protein isolate (WP), sodium caseinate (SC), and soybean protein (SP) as wall materials to encapsulate Pulicaria jaubertii extract (PJ) using freeze-drying. Four formulations of microencapsulation of Pulicaria jaubertii extract (MPJE) were produced, including WPGA-MPJE, SCGA-MPJE, SPGA-MPJE, and GA-MPJE. The formulations were stored at 4 °C and 25 °C for 28 days to assess the storage stability. The results indicated that mixtures of proteins with GA improved the physicochemical properties and bioactive content of the MPJE compared to GA-MPJE. The SCGA-MPJE formula showed optimal values of particle size (450.13 nm), polydispersity index (0.33), zeta potential (74.63 mV), encapsulation efficiency (91.07%), total phenolic content (25.51 g GAE g−1 capsules), and antioxidants compounds, as well as presented a lower release of bioactive composites with high oxidative stability during storage at 4 °C and 25 °C. The microstructure of MPJE formulations showed a flat surface without any visible cracking on surfaces. The microcapsules prepared from protein mixtures with GA, especially the SCGA-MPJE formula, are the most efficient in encapsulating the plant extract derived from the PJ, which could be useful for application in various industrial fields. |
