Abstract: The compound oil, including garlic oil, pepper oil, ginger oil and clove oil, was microencapsulated using β-cyclodextrin as composite wall material, the microcapsule preparation technology condition was optimized through orthogonal experiment, and the optimum technology conditions for compound oil microencapsulation was Moil∶Mβ-cyclodextrin=1∶10, Moil∶Methand=1∶10, the temperature of microcapsule was 50℃, and the time was 1h. The release kinetics of microcapsules was investigated under different temperature conditions by using Avrami’s formula, and release kinetic equation of microcapsules was built at 20℃.
