CHEMICAL COMPOSITION, HEALTH PROMOTING POTENTIALS AND STORAGE PROPERTIES OF BISCUITS SUPPLEMENTED WITH ORANGE PEEL AND PULP FLOURS

📄 Project Abstract

Sweet orange is one of the most important fruits in the tropical and sub-tropical regions of the world. The fruits are usually eaten fresh but are also used for making canned orange juice, frozen juice concentrate, jams, jellies among others. Orange processing industries generate huge amounts of orange peel and pulp as by products from the industrial extraction of orange juices. These peel and pulp contain among other things high levels of vitamin C, dietary fibre and flavonoids. Dietary fibre has been used for the treatment of various gastrointestinal disorders and for such possible health benefits as lowering cholesterol levels, reducing risk of colon cancer and losing weight (Friedman, 1989). Dietary fibre has also been reported to have some nutraceutical potentials (Weingartner et al., 2008). Orange peel and pulp also contain other phytochemicals such as polymethoxylated flavones (PMF) and hesperidin which have hormonal and antioxidant actions and are also involved in enzyme stimu...
