Effect of the different infrared levels on some properties of sage leaves

This study aims to investigate the effect of different infrared powers (IP) (38 W, 50 W, 62 W, 74 W, and 88 W) on drying kinetics, total phenolic content (TPC) and individual phenolics, antioxidant activity (AA) and antibacterial activity, and color quality of sage leaves. IP level significantly affected (p0.80). This study suggested that sage leaves should be dried at 88 W regarding lower drying times and color changes, lower phenolic degradation, and higher antibacterial activity.
