Microencapsulation of Lippia sidoides essential oil was carried out by spray drying. Blends of maltodextrin and gum arabic were used as carrier. Spray dried microparticles
were characterized using conventional (thermogravimetry, evolved gas analysis) and combined (thermogravimetry-mass spectrometry
analysis) thermal analysis techniques in order to evaluate the abilities of carriers with different compositions in retaining
and in releasing the core vs. dynamic heating. Thermal analysis was useful to evaluate the physico-chemical interactions between
the core and carriers and to determine the protective effect of the carriers on the evaporation of essential oil.
