Abstract:
Microwave assisted extraction (MAE) is a rapidly growing extraction technology. It is a process which extracts a solute in a solvent from a solid mixture/micelle/solution substance at optimum conditions of process. The important parameters include solvent type, solvent volume and concentration, extraction time, temperature and microwave power level. In the present study, an antioxidant sesamol was extracted from sesame oil by using MAE process. Optimum conditions for microwave extraction were found at the power level of 800 watt for 7 min of microwave heating with the sample to solvent ratio maintained at 2:25 (w/v). At the optimum processing condition, the amount of sesamol extracted was 374.81 mg/kg of sesame oil. By comparing MAE and the conventional soxhlet extraction processes, it was found that two times more recovery is possible in MAE process within significantly less time than the soxhlet extraction method.
