Performance of microwave-assisted extraction of proanthocyanidins from red sorghum grain in various power and citric acid concentration

Optimized microwave-assisted azadirachtin extraction using response surface methodology

“…The solvent will respond to the microwave emission based on its dielectric properties. The heat generation is produced by the solvent's resistance to ionic migration causing friction between the molecules in the extraction medium [ 40 , 41 ]. The transmission of microwaves to the solvent represents the energy transferred from the magnetron and is controlled by the regulation in the power supply in the microwave [ 42 ].…”
