Modification of Cilembu sweet potato starch with ethanoic acid

Abstract

Abstract. 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.
