This research characterized flour and raw starches isolated from red and white ,sweet potato, cultivars. Their composition, determined by proximate analysis, is typical of ,sweet potato, cultivars. These cultivars have high amylose content (32−34%) and exhibit a Ca-type X-ray diffraction pattern. Similar gelatinization characteristics were detected for both starches with onset temperature of 67 ...

Dietary fiber (DF) was extracted from ,sweet potato, residues after ,starch, isolation of 10 varieties using a sieving method. The proximate composition of ,sweet potato, residues, chemical composition, monosaccharide composition, and physicochemical properties of DF were investigated. The average yield and DF content of DF products from 10 ,sweet potato, varieties were 9.97 and 75.19%, respectively.

Sweet potato leaves can also be used to support small-scale aquaculture, even though the phytic acid content (3.29%) is considered high for fish growth (DONGMEZA et al., 2009). Other antinutritional compounds reported in sweet potato leaves are tannic acid and oxalic acid at levels of 491 and 470mg 100g-1 respectively (MOSHA et al., 1995).
