Fruits and vegetable wastes-Potato peels-Guava seeds -Pomegranate peelsHypercholesterolemia -Liver functionsHigh fiber cake.The present investigation aimed to assess the possibility of using some fruits and vegetable wastes including potato peels, guava seeds and pomegranate peels as different sources of dietary fiber. Dietary fiber from potato peels, guava seeds and pomegranate peels were used in preparation high fiber cakes at the levels 5, 7 and 10% dietary fiber. Thirty male albino rats were fed with basal diet and0.25% cholesterol for 6 weeks to induce hypercholesterolemia then the diet was administered with the best dietary fiber cakes (5% dietary fiber) for another 6 weeks. The results showed that the pomegranate peels contained a high percentage of crude fiber, ash and total dietary fiber. Insoluble fiber in tested wastes was higher than soluble fiber. Regarding to the reheological properties of the prepared cake samples, the addition of the wastes dietary fiber at high levels led to increase the water absorption while the mixing time and mixing stability of the dough were decreased. The organoleptic properties recorded the higher grades for the cake samples prepared with 5 and 7% guava seeds followed by 5% of potato peel and 5% pomegranate peel. The feeding experiments of rats for other six weeks on the tested cake samples at the level 5% (which was the best choice in organoleptic and rheological properties) led to decrease the relative body weight of rats and reduced the levels of triglycerides, liver cholesterol, serum cholesterol and LDL-cholesterol. The liver functions for all the groups of rats feeding with tested cake samples were within normal limits and the absorption of iron and copper were retarded.Copy Right, IJAR, 2017,.

Introduction:-Potato, guava and pomegranate are considered among the most popular fruits and vegetables grown in Saudi Arabia. These fruits and vegetable are a highly preferred in processing for their color , flavor beside, it is a good source of vitamins , minerals and fiber (Anon, 1998). It is well known that guava seeds and pomegranate peels are widely processed from fresh juices industry while potato peels is a waste from the potato chips industry. Potato peels, guava seeds and pomegranate peels are the most important wastes remaining after the processing of potato, guava and pomegranate respectively. These wastes represented about 20.2, 32.5 and 42.3% of the fresh weight of potato, Corresponding Author:-Nermin N. El-Nashar.
