| Abstract | ||||
| Indonesia has the highest population of sago plant globally. The plant contains high carbohydrates and supporting food diversification. Therefore, this study examined the effect of lactic acid hydrolysis and hydrogen peroxide oxidation (HPO) under ultraviolet irradiation (UV-i) time on the properties and characteristics of modified sago starch. Furthermore, the pH, water content, color, carbonyl groups, carboxyl groups, swelling power, solubility, oil absorption capacity (OAC), baking expansion, frying expansion, Fourier Transform Infrared (FTIR), and X-Ray Diffraction (XRD) were analyzed. The results showed UV-i time and hydrogen peroxide oxidation (HPO) had a significant effect (P | ||||
