Previous investigations suggested the orange essential oil as antimicrobial and natural antioxidant; however, the high volatility and sensibility due to extern factors are imitating its applications. Thus, the encapsulation is an ideal alternative of protection for essentials oils and the molecular inclusion has greater advantages compared to others, but the drying method and temperature can influence its characteristics and stability. Therefore, the orange essential oil was microencapsulated into beta-cyclodextrin (β-CD), and was evaluated the effect of drying by stove, lyophilization and atomization (160, 180 and 200 °C) on humidity, water activity, encapsulation efficiency, yield, and stability (82% relative humidity for 36 days). The microparticles were analyzed by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). The best drying method was lyop...
