The pectin yield was increased from 320 to 510 w by due to the heating principles of ionic conduction and dipole rotation of MAE [16]. The electromagnetic energy was transferred rapidly on the bio-molecules by ionic conduction and dipole rotations, which result more power was dissipated inside the solvent and plant materials which generate molecular movement and heating [17]on the extraction system rapidly and enhanced the คลาย
of the cell wall matrix quickly, increases the penetration of the solvent into the plant matrix which leads to enhanced the leaching of pectin from plant material to solvent. The yield was decreased with increasing the power beyond 510 w
