| description | Caffeine is a stimulant that is commonly found in many foods and drinks that we consume. Concerns exist about the potential adverse health effects of high consumption of dietary caffeine, especially in children and pregnant women. Recommended caffeine intakes corresponding to no adverse health effects have been suggested recently for healthy adults (400 – 450 mg/day), for women contemplating pregnancy (300 mg/day), and for young children age 4 – 6 years (45 mg/day). Different brands of soft and energy carbonated beverages available on the Romanian market were analysed for caffeine by HPLC with a diode array UV-VIS detector at 217 nm. The column was a reverse phase C18 and the mobile phase consisted of potassium dihydrogen orthophosphate buffer (0.02 mol/L, pH 4.3) and acetonitrile (88:12, v/v). The caffeine contents in energy drink samples ranged from 16.82 mg/100 mL to 39.48 mg/100 mL while the carbonated soft drink group showed caffeine content in the range of 9.79 – 14.38 mg/100 mL. In addition, the concentrations of caffeine have been converted into the daily intake doses based on beverages consumption. The mean values of caffeine daily intakes were 124 mg and 49 mg through the ingestion of energy drinks and soft drinks, respectively. |
