The dietary fiber, total phenolic content, and antioxidant activity of orange peels [electronic resource].

Includes reference.

This investigation was carried out on the dried orange peels. High dietary fiber content was prepared from orange peels. The dietary fiber composition, total phenolic compounds and antioxidant activity of dried orange peels were studied. Methanolic orange peel extract as a natural source of antioxidant was evaluated during 6 months storage of refined sunflower oil at ambient temperature.The total dietary fiber content in orange peels was 70.95%, with an appreciable amount of soluble fiber (21.64%). Insoluble dietary fiber was the predominant fraction in orange peels (49.31 %). The studied orange peels contained the best ratio of soluble/insoluble fractions (1.02.28).
