| Wall materials | Core materials | Concentration | Results | Reference |
|
| Individual MD and MD-GA combination (4 : 1) | Lemongrass EO | 15–30% | MD in individual form at 30% of concentration effectively encapsulated lemongrass EO at high encapsulation efficiency (84.75%) and oil retention (89.31%) | Thuong Nhan et al. [34] |
| MD and GA combination | Lavender EO | MD (25–58.33 of total solid) and GA (25–50% of total solid) | The highest encapsulation efficiency was obtained and minimum oil loading | Burhan et al. [33] |
| HPMC-MD-CSD mixtures (1 : 1:0 and 2 : 1:1) | Oregano EO | NA | The relation 2 : 1 (WM : C) without CSD enhanced the antioxidant activity and retention of volatile compounds after 90 days of storage | Asensio et al. [59] |
| Mesquite gum (MG), nopal mucilage (NM), and MG-NM mixtures (1 : 3, 1 : 1, and 3 : 1) | Lemon EO | 30% of total solid content (w/w) | MG-NM combination exhibited a synergic effect in giving rise to desirable retention and shelf-life extension for lemon EO | Cortés-Camargo et al. [60] |
| MD-IP, MD-OSA, and MD-OSA-IP | Avocado EO | OSA equals to 3% MD base and IP : MD ratio equals to 1 : 9 | The OSA modification of MD reduced by about 80% the oxidation of the EO as compared to its nonmodified counterpart | Sotelo-Bautista et al. [61] |
| GA, MD, MS, GA-MD mixtures (3 : 1, 1 : 1, 1 : 3), GA-MS mixtures (3 : 1, 1 : 1, 1 : 3), and GA-MD-MS mixtures (1 : 1: 1, 4: 1: 1, 1: 4: 1, and 1: 1: 4) | Lemon EO | 30% | GA produced the highest encapsulation efficiency, followed by MS and MD. | Kausadikar, Gadhave, and Waghmare [62] |
