Abstract : The antioxidant activity of a high dietary fibre mango peel product and of some commercial samples was determined by the ferric thiocyanate colorimetric method. At a concentration of 0.05%, the antioxidant activity of mango peel dietary fibre was 0.75 times as effective as that of 2-tert-butyl-4-hydroxyanisol (BHA) and 1.4 and 3.4 times higher, respectively, than that of French PARAD'OX (a commercial polyphenols concentrate) and of DL-?-tocopherol. All Bran, Quaker Oats, lemon and apple fibre did not exhibit any antioxidant capacity. It is concluded that the obtention of high dietary fibre products with active compounds could be useful for the food industry and the antioxidant activity may be a new property to consider in the quality evaluation of these ingredients.
