Abstract
Objective: This study was to determine the amounts of carboxylic acids in 10 kinds of energy drinks in order to estimate the cariogenic effect of energy drinks.
Methods: Carboxylic acids in energy drinks were analyzed in polar endcapped-reversed phase column as stationary phase, and 50 mM sodium sulfate (pH 2.64 adjusted MSA) as mobile phase, and then detected at UV 210 nm. Ten kinds of energy drinks were diluted with distilled water and filtered before the analysis.
Results: All energy drinks contained citric acids, while oxalic acid, lactic acid, acetic acid, maleic acid, and succinic acid were not detected in all drinks. Tataric acid, malic acid, ascorbic acid, and fumaric acid are detected in some of drinks. The range of pH was 2.45-3.62, and that of total carboxylic acid concentration were 5.07 to 45.50 mM.
Conclusion: Considering the low pH and carboxylic acid amount of energy drinks, these drinks can sufficiently cause hardness loss in enamel. Therefore, energy drinks is harmful to oral health.
