Study of vanilla essential oil extraction : comparison through heat and wave principles

To extract an essential oil the method used is extraction without using organic solvent. The conventional method used is hydro distillation (HD) that applies heat principle. However, a new green technique for essential oil extraction that is microwave which is applies wave principle was developed in...
