Abstract:
This study was carried out to determine caffeine in fourteen brands of carbonated and energy drinks available in local market in Dharan, Nepal. Quantitative analysis of caffeine was performed by a simple and fast standard UV spectrophotometric method. Among all the soft drinks highest amount of caffeine was found in XL(I) ( 520μg/ml) and lowest was found in Tender coconut drink 52.37μg/ml. In a comparision between caffeine content in same soft drink prepared in Nepal and imported from foreign nation, it was found caffeine content in imported drink was higher. Similarly taking Recommended Daily Intake value as a reference maximum volume of soft drink a person can consume is calculated.
