Assessment of scale-up parameters of microwave-assisted extraction via the extraction of flavonoids from cocoa leaves

Microwave-assisted extraction (MAE) is a promising technique for the extraction of flavonoid compounds from plants. However, it is difficult to scale up due to the complex mass transfer involved. This has prompted the study of parameters for scaling up the system by considering energy-related parame...
