Abstract

This study aims to determine the physical and chemical properties of porang starch. This research was carried out at the Agricultural Product Chemistry Laboratory, Faculty of Agriculture, Sriwijaya University from 22 April 2021 to September 2022. This study used a Completely Randomized Factorial Design (RALF) with two treatment factors. The treatment was repeated three times. The first factor is pH of citric acid (A1 = pH 3, A2 = pH 4, and A3 = pH 5) and the second factor is the soaking time of porang flour (B1 = 2 hours, B2 = 3 hours, B3 = 4 hours, and B4 = 5 hours). The parameters observed in this study were physical properties (swelling power (SP), solubility index (IK), and color), and chemical properties (calcium oxalate content, water content, ash content and protein content). The results showed that the pH of citric acid and the immersion time of porang flour significantly affected the decrease in calcium oxalate levels, but significantly increased the swelling power, solubility index, and water content. The immersion time has a significant effect on the increase in color in redness and yellowness. The interaction of citric acid pH and the immersion time of porang flour had a significant effect on decreasing calcium oxalate levels, but significantly on increasing swelling power and color on redness and yellowness. The best decrease in calcium oxalate levels was found in sample A1B3 (pH 3 for 4 hours), amounting to 71,68%.
