In this study, the modeling of the concentration of sage extracts and the effect of concentration on the quality properties of sage extracts were investigated. For this purpose, applications were performed in two different concentration systems: thermal vacuum concentration (75, 80 and 85 ºC, 250 mbar pressure) and microwave vacuum concentration (180, 300, and 450W, 250 mbar pressure). The desired 40 °Bx concentration level in the shortest time was reached by the microwave vacuum concentration application at 450 W. 13 different mathematical models were used to describe the concentration kinetics. While the best fit with the sage samples concentrated by thermal method was the Modified Henderson and Pabis model, the model that showed the best fit for the samples concentrated by the microwave method was Midilli. It was observed that there was no significant difference in the physicochemical properties of the concentrated samples.
