Abstract
"Three apple varieties cultivated in Chile were studied: Granny Smith, Royal Gala and Fuji (whole and apple flesh). Total polyphenol content in whole and apple flesh is presented in the decreasing order: Granny Smith > Royal Gala > Fuji. The antioxidant capacity shows significant differences among the varieties in both, whole apples and apple flesh, presenting the same decreasing order. Apple dehydration at 60 ºC for 4 hours to obtain flakes keeps polyphenol content high, with values of 372.81, 391.47 and 358.54 mg GAE/100 g wb for Granny, Royal and Fuji varieties respectively. Antioxidant capacity is 7.62, 5.1 and 4.24 mmol Fe/100 g wb for the varieties above mentioned. The addition of citric acid and sodium bisulfite - as antibrowning agents- before drying has a protective effect on polyphenols. There is a correlation between polyphenol content and antioxidant capacity in peeled fresh apples (R2 = 0.8081) and whole apples (R2 = 0.7585)."
