Agro-industrial co-products derived of fruit processing represents an important source of bioactive compounds as fiber, antioxidants and prebiotics. The objective of this work was to determine the content of fiber, antioxidant capacity and prebiotic activity of three flours obtained from commonly co-products (banana peel, apple peel, and carrot bagasse). The results showed a higher total fiber content in carrot bagasse, and lower in apple peel. Significantly differences were found in antioxidant activity. Fruit co-products flours were a suitable carbon source increasing specific growth rate with a reduction in duplication time as compared to glucose. The prebiotic activity was positive in the three co-products, all flours survived at pH 1.0 and showed resistance to simulated gastric acid for about 60 min. Banana peel, apple peel and carrot bagasse showed to be a good source of bioactive compounds as fiber and antioxidants and can be used as prebiotics for lactic acid bacteria.
