ABSTRACT
Caffeine is a stimulant drug and beneficial to most human being when taken in at low-to-moderate amount, whereas at high amount it may have negative impact on health. Recently the caffeine is being added by companies in energy drinks and other beverages. The aim of this work was to determine the caffeine concentration, pH and acidity in a few energy drinks brands namely sting, booster six B, gourmet spark and powerful locally available in Lahore, Pakistan, and to compare the results with the labeled caffeine concentration and FDA recommended concentration, which is maximum 400 mg/day. The maximum amount of caffeine determined in Gourmet spark was 9.89 mg /100 ml, whereas powerful brand had minimum caffeine amount (9.34 mg/100 ml).pH were measured by pH meter at 20 oC and were found 3.47, 3.37, 3.20 and 3.57 for sting, booster six B, gourmet spark and powerful, respectively. The %age of acidity were found to be 1.267, 1.670, 1.868 and 1.785 for sting, booster six B, gourmet spark and powerful, respectively. The results showed that caffeine concentration would remain below moderate level if anybody took two serving size packs of anyone selected sample and consequently would have no negative impact on health.
