Abstract

Pineapple and dragon fruit have good antioxidant content so that they can be developed into more attractive preparations, one of which is effervescent granules with varying concentrations of citric acid and sodium bicarbonate. This study aims to determine the effect of variations in citric acid and sodium bicarbonate concentrations on the physical properties of effervescent granules. Method: This study is an experimental study with a combination of pineapple juice and dragon fruit juice formulated in effervescent granule preparations with varying concentrations of citric acid and sodium bicarbonate. The physical properties were then tested including pH, water content, flow rate, angle of repose, dissolving time and Loss On Drying (LOD). Results: The results of this study showed that the three formulas met the requirements except for the examination of pH in F1 and angle of repose in F2, F3 did not meet the requirements. pH ranged from 4-7, moisture content between 0,40-1,00%, flow speed between 5,35-9,96 seconds, angle of repose 39.11-48.92, dissolving time between 3,01-1,48 seconds and Loss On Drying (LOD) ranged from 1,31- 4,4%. Conclusion: The higher concentration variation of citric acid and sodium bicarbonate affects pH, water content, flow rate, angle of repose, dissolving time and Loss On Drying (LOD).
