Kinetics of Ultrasound-Assisted Extraction of Anthocyanin from Purple Roselle Calyces under different pH Conditions

This research presents that the higher temperature results on higher extracted anthocyanin. In addition, it was found that pH 2 was preferable for obtaining greater anthocyanin content. Employing the second-order kinetics model in this research confirmed the good fitting of the model and experimental data.
