In this study, two kinds of chestnut-sweet potato (CSP) and pumpkin-sweet potato (PSP) were cooked by three methods: raw, steaming, and roasting. These samples were investigated in food compositions such as moisture, protein, ash, dietary fiber, fat, minerals, and vitamins. As the results of this study, the moisture contents of raw CSP and raw PSP were higher than those of steamed and roasted samples in two cultivars. The contents of protein in raw CSP and raw PSP were 2.57 g/100 g and 3.22

The potassium, phosphorus, magnesium, calcium, sodium, and iron values of PSP were 1,048.46 mg/100g, 152.02 mg/100g, 74.70 mg/100g, 57.22 mg/100g, 22.28 mg/100g, and 1.44 mg/100g, respectively, which were the highest values in tested sweet potato cultivars. The content of dietary fiber in CSP was higher generally
