In this study, microwave and ultrasound extraction were selected as process intensification tools to intensify the conventional heat reflux extraction process. Process efficiency was evaluated based on total phenolic content (ascorbic acid, neochlorogenic acid, and chlorogenic acid), scavenging ability of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric (Fe3+) free radicals, and process intensification principles and domains. Highest phenolic content and antioxidant activity were achieved using microwave extraction followed by heat reflux and ultrasound extraction. Microwave extraction was selected via decision matrix as a suitable process intensification approach based on results and its ability to satisfy process intensification principles.
