ascorbic acid contents (Genovese et al., 2008), and, consequently, it was affected by drying processes. Lyophilization was shown to cause a slight decrease in FC and DPPH (13–14%) and a 26% reduction in FRAP (Fig. 1). Spouted bed drying resulted in temperature-independent decreases in antioxidant capacity. Folin–Ciocalteu reducing (46–67%) and DPPH scavenging capacities (61–71%) reductions were greater than those for the FRAP (22%–46%). This behavior could be explained by differences in losses of ascorbic acid, proanthocyanidins and total phenolics among the processes (Table 3).
