Abstract
Purple sweet potato PSP) is a type of tuber crops that contains high carbohydrate in the form of starch, and anthocyanin pigments which have antioxidant activity. Processing PSP into flour and starch, besides increasing shelf life, also increases the added value of the tuber product. Processing of PSP starch produces solid waste, and in this study, it is processed into flour containing fiber. Flour, starch, and fiber flour from are then made into composite flour composite flour with a ratio of 75:15:10, and are used as raw materials for making plain bread. Chemical characteristics including proximate composition, anthocyanin content, and dietary fiber content, as well as energy adequacy level, and dietary fiber from bread produced were analyzes, and compared with bread made from 100% PSP flour and 100% wheat flour. The results showed bread made from composite flour consisting of flour, starch and fiber flour of PSP had insignificant different for protein and carbohydrate content, lower fat, and ash content than bread made of 100% PSP flour, and 100% wheat flour, but it has a higher content of dietary fiber. The daily energy adequacy level of bread from flour, starch and fiber of PSP is 6.88%. Keywords: Purple sweet potato flour, solid waste of starch, bread, fiber
