Abstract:
Energy drinks are the beverages which include variable combination of different energy enhancing ingredients similarly soft drinks are the combination of different flavouring agents, sugar, carbon dioxide and water. This research did to determine the pH, TDS, Electrical conductivity, Caffeine and Sodium concentration in ten soft drinks and six energy drinks available in local market of Lahore, Pakistan. pH, TDS and electrical conductivity were measured by pH meter (pH 7110) and TDS/Conductivity meter (3145 conductivity meter) respectively. Caffeine was extracted from samples by solvent extraction method using CCl4 as extracting solvent, caffeine's quantitative estimation was performed by UV-Visible spectrometer (CECIL 7200) at 270 nm. Sodium content in samples were determined by flame photometer. The pH of the soft drink and energy drinks was found in the range of 2.42-3.35 and 2.89-3.31respectively. The TDS of soft drinks and energy drinks was found in the range of 139.5-486 mg/l and 237817 mg/l respectively. The conductivity of soft drinks sample and energy drinks sample was in the range of 229-808 µS and 394-1362 µS respectively. The caffeine content in soft drinks and energy drinks was found in the range of 10.5-34 mg/serving and 15-79.5 mg/serving respectively. The concentration of sodium in soft drinks and energy drinks was found in the range of 10 to 50 mg/serving and 30 to 105 mg/serving respectively. Soft drinks and Energy drinks are acidic in nature, values for TDS, Conductivity and Concentrations of caffeine and sodium were higher for Energy drink samples than Soft drink samples.
