Evaluation of the microencapsulation of orange essential oil in biopolymers by using a spray-drying process.

ABSTRACT: Essential oils are volatile compounds commonly used by several industries, easily degradable, which restrains their applications. Therefore, we developed and validated a methodology for producing microcapsules loaded with orange essential oil, using a spray-drying process. The experimental design results showed that the combination between a low flow transfer rate (0.15 L h^-1) of the colloidal suspension, a higher drying air flow rate (536 L h^-1), and an inlet air temperature of 150 °C to the spray-dryer were the most important parameters for the atomization efficiency. The method optimization resulted in microcapsules with powder recovery between 7.6 and 79.9% (w w^-1), oil content ranging from 8.9 to 90.4% (w w^-1), encapsulation efficiency betwe
