“…In spite of previous studies on drying processes of tangerine peels [ 12 , 16 , 17 ], there is no detailed report on the influence of different drying methods on the nutraceutical components in tangerine peels, which are important indexes for assessing the quality of dried tangerine peel. This study systematically investigated the influence of different drying methods (sun drying, hot-air drying, freeze drying, vacuum drying, and medium- and short-wave infrared drying) on the main compositions of tangerine peels (moisture, soluble solid, reducing sugars, total sugar, crude fiber, titratable acid, ash content, and minerals), major functional components (total phenolic compounds, total flavonoids, hesperidin, synephrine, and vitamin C), and the antioxidant activity of the dried tangerine peels.…”
