Antioxidant compounds associated with some types of dietary fibres may be responsible in part for the beneficial effects on health of high-dietary-fibre diets. The antioxidant activity of a high-dietary fibre mango peel product and of some commerical samples was determined by the ferric thiocyanate colorimetric method. At a concentration of 0.05%, the andioxidant activity of mango peel dietary fibre was 0.75 times as effective as that of 2-tertbutyl-4-hydroxyanisol (BH) and 1.4and 3.4. times higher, respectively, than that of French PARAD'OX (a commerial polyphenols concentrate) and of DL-alpha-tocopherol. All Bran, Quaker Oats, lemon and apple fibre did not exhibit any antioxidant capacity. The obtention of high-dietary-fibre products with bioacive 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.
