Standardization of Microencapsulation Process of Volatile Oil of Azadirachta indica

Neem oil microcapsule gel was successfully prepared with wall material including gelatin and gum Arabic using coacervation technique by the researcher as an outcome of standardization of microencapsulation process of volatile oil of Azadirachta indica. An essential oil is the volatile lipophilic component extracted from plants. The use of medicinal plants is a universal phenomenon. The plant Neem belongs to the big mahogany family of Meliaceae and the genus Azadirachta of A. indica. The diverse biological activities of Neem essential oils can be applied on a large scale as antioxidant, antimicrobial agents comprising many important benefits including their volatility, lower level of risk to the environment than with synthetic ones. Findings of the study revealed that best results of microcapsules formation using Neem oil were obtained when the ratio of oil:gum:gelatin was kept 2:4:4, at optimized 50°C temperature having initial pH 4.5 and final pH 9.5.
