The objective of this study was to investigate the factors affecting the microencapsulation process of corn mint (Mentha arvensis L.) essential oil using the spray drying method. Different impact factors were evaluated including concentration of maltodextrin (20-30%), concentration of essential oils (0.5-2.0%), homogenization method, inlet temperature (130-150°C), and feed flow rate (4 -10 mL/min). The suitable conditions were the wall material concentration of 25% (w/ w), essential oil concentration of 1.5% (w/w), using rotor-stator blend, the temperature of 140°C, and feed flow rate of 8 mL/min. The microencapsulation efficiency, the microencapsulation yield and spray-drying yield were 98.9%, 68.6%, and 84.8%, respectively. |
