Anacardium occidentale L. leaves extraction via SFE: Global yields, extraction kinetics, mathematical modeling and economic evaluation

The purpose of this work was to obtain extracts from Anacardium occidentale leaves using supercritical fluid extraction (SFE). The use of ethanol and isopropyl alcohol as co-solvents was evaluated. Mass transfer kinetics experiments were performed, and overall extraction curves were modeled. SFE pro...
