Physicochemical Properties of Sago Flour Food Bars Fortified with White Sweet Potato Flour and Sidat Fish Flour

Food bars are alternative fast foods with high calorific value because they are enriched with various nutrients available in natural ingredients. While the benefits that can be obtained from food bars made from various flour are the nutritional value in food bars such as calories, carbohydrates, reducing sugars, protein fats, water, ash, and fibre. Sweet potato (Ipomoea batatas) is a type of plant whose roots are edible. All sweet potato varieties can be used in making flour, sweet potato flour is a crushed sweet potato which is partially removed from its water content. The use of protein fortification of eel fish will enrich the nutrition of food products. The purpose of this study is expected to provide information about sweet potato plants as a source of carbohydrates that can be processed in making white sweet potato flour and eel fortification sago flour as an alternative food. So the researchers used a Completely Randomized Design, which consisted of one factor with the type of sweet potato flour, sago flour, fortification of eel fish meal. Morphological results of starch granules morphology in food bar products using Scanning Electron Microscopy (SEM). Starch granules micrographs in food bars in all treatments show that starch granules are not compact and still have quite large fibre between starch granules, and have non-uniform starch granule density due to fibre. In addition, the nutritional content of food bars shows that the use of sweet potato flour and sago flour, as well as the fortification of 5% eel fish meal (T2), provides the best value of formulation treatments that are recommended for development as food bar products. However, it is necessary to add other nutrients such as vitamins, minerals to enrich the nutritional value of food bars as energy and nutritious fast food.
