Nutritional characteristics of dehydrated fruits are also evaluated as quality parameters. Ascorbic acid content is usually adopted as the quality index of nutrients in food processing and storage [6]. Authors assume that if a significant portion of vitamin C content is retained after processing, other nutrients are also likely to be
preserved because the ascorbic acid is extremely unstable to heat, oxygen, light, pH, moisture content, and heavy metallic ions (Cu2+, Ag+ e Fe3+)
