This study aimed to compare the physicochemical characteristics and antioxidant properties of apple pomace (AP) and apple juice (AJ) to provide a basis for the utilization of AP. The samples were obtained from commercial Korean apples, Fuji (Malus pumila), and dried in a rotary drier at 80℃ for 12 hours. The total soluble solids and reducing sugar content of AJ were significantly higher than that of AP, but the pH was significantly lower. The total content of polyphenols and flavonoids of AJ was significantly higher. The corresponding content of AP was 65.2% that of AJ. The antioxidant activity (2,2-diphenyl-1- picrylhydrazyl [DPPH], 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activities [ABTS], ferric reducing antioxidant power [FRAP], and Reducing power) also showed a trend similar to that of the antioxidant components. Thus, the polyphenol content of AP reached an average of 65.2% compared to that of AJ, indicating that AP still contained a considerable amount of antioxidant components. This suggest that AP has significant potential as a sustainable ingredient for the development of apple pomace-based products.
