Influence of spray drying parameters on the physicochemical characteristics of microencapsulated pomelo (Citrus grandis (L.) Osbeck) essential oil.

ABSTRACT: This study aimed to evaluate the encapsulation of pomelo (Citrus grandis (L.) Osbeck) essential oils using the spray drying technique. The parameters of the process include concentration of maltodextrin (20-35% by wt%/wt%), concentration of essential oil (1-2.5% by wt%/wt%), inlet temperature of spray drying (120-180 °C), and feed flow rates (120-240 mL/h) were soundly examined. The utilization of suitable parameters as the concentration of maltodextrin at 30% (by wt%/wt%), the concentration of essential oil at 1.5% (by wt%/wt%), the inlet temperature of 140 °C, and feed flow rate of 120 mL/h showed the highest drying yields (90.05%), microencapsulation yield (75.59%), and microencapsulation efficiency (89.44%). TGA and DSC results verified higher stability of Citrus grand
