An apple snack has been developed with the purpose of introducing foods derived from fruit to reduce obesity in school children of Santiago, Chile. Apple slices of the ‘Fuji’ variety were dehydrated, with skin included, at 60°C for 4 h obtaining a product with 4.6 g/100 g of humidity and water activity (Aw) of 0.56. The apple snack presented 24.8 ± 0.3 g/100 g b.s. of dietary fiber and 550.16 ± 5.89 mgGAE/100 g b.s of polyphenols which converts into a healthy food, it also presents high antioxidant capacity measured by FRAP, with 0.59 mmolFe/100g.
