COMPLEXOS DE INCLUSÃO BINÁRIOS, TERNÁRIOS E QUATERNÁRIOS CONTENDO ÓLEO ESSENCIAL DE Lippia sidoides

The aim of this work was the production and characterization of binary, ternary and quaternary complexes based on β-cyclodextrin (β-CD) and Lippia sidoides essential oil (EO). OE:β-CD formulations at proportions of 1:10 to 2:10 (binary); added with surfactant or polymer (ternary) or with both (quaternary) were prepared and submitted to spray drying at optimized operating conditions (inlet gas temperature: 160 °C, drying gas flow rate: 60 m3/h; feed flow rate: 4 g/min; pressure and flow rate of the atomizing air: 2.5 kgf/cm2 and 17 lpm). The responses evaluated were the encapsulation effici...
