Quantitative determination of artificial sweeteners and sucrose in energy drinks and mango juice available in Dhaka city

Abstract

Energy drinks and mango juice are popular beverages. Apart from the natural ingredients and some additives present in these drinks, sugar is an important component of both. It has been established that, other than providing sweetness, sugars are potent to bring about health consequences for their consumers. Sweeteners, both artificial (aspartame, sodium cyclamate, and saccharin) and natural (sucrose), were our centers of interest. This study aimed to determine the presence and levels of these sweeteners in energy drinks and mango juice. Spectrophotometric methods were used to determine the concentration of the mentioned sugars. For this purpose, a total of 42 samples of 7 different brands were collected from different locations in Dhaka city, Bangladesh. The methods were found to be linear over the concentration range of 10-26 µg/mL (r2=0.9989), 137-320 µg/mL (r2=0.9891), 2.5-24 µg/mL (r2=0.9915) and 2354-2784 µg/mL (r2=0.9985) for aspartame, sodium cyclamate, saccharin, and sucrose, respectively. Mango juice contained a relatively lower amount of saccharin compared to energy drinks. In the case of aspartame, one brand of energy drinks had the least amount. Moreover, both energy drinks and mango juice had a similar content of sodium cyclamate, but one brand of mango juice had a relatively low content of sodium cyclamate.
