Further investigations are needed to determine the suitability of these energy drinks. Brand-1 has the lowest and Brand-4 has the highest reducing sugar providing an idea about the sugar contents of energy drinks. The reducing sugar content of the energy drinks ranged from 73.80 mg/serving to 136.08 mg/serving. The levels of caffeine in all energy drink samples are well below the maximum allowable limits set by the food regulatory bodies, except Brand-5. Quantitative 1 H NMR spectroscopy was applied for the analysis of taurine in energy drinks by Rouger 24 et al. The minimum caffeine level was observed in Brand-4 (40.34 mg/serving), while Brand-5 showed the highest caffeine content (244.57 mg/serving) showing a range from 40.34 to 244.57 mg/serving. One substantial subcategory of soft drinks that is considered to be one of the most popular is represented by energy drinks (EDs). Caffeine (generally 32 mg/100 mL) together with a wide variety of other active components such as taurine (usually 4000 mg/L) and D-glucuronolactone (generally 2400 mg/L) are the main ingredients of EDs. Results showed that the pH of the beverages were perfectly acidic ranging from 2.85 to 3.11. The consumption of energy drinks (EDs) is increasing globally while the evidence and concern about the potential health risks are also growing. The deviation between 1H NMR and LCUV/vis results was. In this paper we describe the quantification of taurine in energy drinks by 1 H NMR as an alternative to existing methods of quantification. Reducing sugar content of the energy drink was also determined spectrophotometrically. Taurine concentrations in 20 different energy drinks were analyzed by both using 1H NMR and LCUV/vis. Quantitative estimation of caffeine was performed by a simple and fast standard UV spectrophotometric method, using carbon tetrachloride as the extracting solvent. The popularity of energy drinks has been on the rise since 2006, and it is important to have an efficient way to determine the concentrations of ingredients in the drinks. However, some studies have shown that there may be risks of combining taurine with large doses of caffeine (such as those found in certain types of energy. This investigation was carried out to determine the pH, levels of caffeine and reducing sugar contents in five energy drinks available in local market in Rajshahi, Bangladesh. The concentration of taurine in two energy drinks, Monster Lo-Carb and -Hour 5 Energy, was found by using high-performance liquid chromatography. So far, the high taurine concentrations of energy drinks in comparison to the rest of the diet are scientifically doubtful, as the advertised physiological effects and the value of supplemented taurine are unproven.Though the popularity of energy drinks is increasing day by day no considerable chemical studies on it has not yet been done in Bangladesh. Risk analysis of these products is difficult due to the lack of valid toxicological information about taurine and its interferences with other ingredients of energy drinks (for example caffeine and alcohol). Source: USDA National Nutrient Database for Standard. During analysis of 80 energy drinks, a median concentration of 3180 mg/l was found in alcohol-free products, 314 mg/l in energy drinks with spirits, 151 mg/l in beer-containing drinks and 305 mg/l in beverages with wine. The human body contains 70 times more taurine than one 8.4 fl oz can of Red Bull. The determination of taurine in energy drinks by FTIR was compared with amino acid analyzer (ion chromatography with ninhydrin-postcolumn derivatization). In this article, we describe a fast and efficient analytical method (FTIR-spectroscopy) that is able to reliably characterize and quantify taurine in energy drinks. To control the currently valid maximum limits of taurine in energy drinks, a simple and rapid analytical method is required to use it routinely in food monitoring. One example is that taurine is used for energy production. The human body uses taurine for actions in cells. Taurine occurs naturally in foods with protein, such as meat or fish. Cardiac parameters from three different groups were measured. Taurine, in certain amounts, is a safe drink ingredient in the United States. In a study by Baum and WeiB, the effects of taurine and caffeine in young athletes were examined. So-called energy drinks with very high amounts of taurine (up to 4000 mg/l are usually granted by certificates of exemption) are increasingly offered on the market.
