MODELING SOLID–LIQUID EXTRACTION KINETICS OF TRANS-RESVERATROL AND TRANS-ε-VINIFERIN FROM GRAPE CANE (pages 103–112)

摘要

Solid–liquid extraction of resveratrol and viniferin from grape cane samples wasndescribed by using first-order kinetic model, Peleg’s model, two-site kinetic modelnand modified Gompertz equation. Goodness of fits of the models were evaluated byncomparing the adjusted determination coefficient and root mean square error andnmean percentage error values.Although the two-site kineticmodelwith four parametersndescribed the data better, Peleg’s model, with only two parameters, couldnexplain the data with a slight loss of goodness of fit. The modified Gompertznequation showed theworst performance for describing the solid–liquid extraction ofnstilbenes.
