【 摘 要 】

Cilembu sweet potato harvest was abundant, its use was still limited. Starch was required by various industries. Starch is generally beige, and requires a long time for the drying process. The purpose of this research was to produce a modified starch with ethanoic acid. The method used in this study was the experimental method. The results showed acid modified starch yield was 18%, with the color characteristics of L∗: 96.38 ± 0.82; a∗: -0.70±0.02; b∗: 2.70±0.03; C: 2.79±0.02. Native starch yield was 16%, with the color characteristics of L∗: 93.55 ± 0.91; a∗: -0.86±0.06; b∗: 2.93±0.04; C: 3.05±0.03. The conclusion of this study was modified starch of Cilembu sweet potato using ethanoic acid have higher yield and more white bright than native starch.
