Abstract

This study aimed to determine the effect of citric acid and sodium bicarbonate (NaHCO3) addition on quality of carbonated ginger juice drink. This research was carried out on November 14th until December 9th 2022 at the Chemical, Sensory, and Agricultural Product Processing Laboratory, Agricultural Product Technology Study Program, Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University. The method used in this study was a completely randomized factorial design (RALF) with two treatment factors, namely citric acid concentration (0.10% w/v and 0.20% w/v) (factor A) and sodium bicarbonate concentration (NaHCO3) (1500 ppm, 3000 ppm, and 4500 ppm) (factor B). Each treatment was repeated 3 times. Observed parameters were pH, total titrated acid, total dissolved solids, and organoleptic tests (hedonic tests of carbonation effect and taste). The results showed that addition of citric acid (factor A) had a significant effect on the pH value of carbonated ginger juice drink. Moreover, sodium bicarbonate (NaHCO3) (factor B) had a significant affected the total pH and value titrated acid. Based on hedonic test, A2B1 treatment (citric acid concentration of 0,20% and sodium bicarbonate (NaHCO3) concentration of 1500 ppm) had the highest level of panelist preference (3,33 of carbonation effect and 3,30 of test).
