Artificial sweeteners such as acesulfame-potassium (ACE-K). saccharin (SAC), and aspartame (ASP), play a vital role in the food industry. Despite apparent benefits, several studies report adverse reactions on consumers. EFSA is currently re-evaluating several individual sweeteners, including ASP, Ace-K and SAC that shall be completed by 31 December 2020. Our goal was to evaluate, by liquid chromatography with ultraviolet detection (LC-UV), their levels in non-alcoholic beverages from the Portuguese market (soft drinks, sport drinks, energy drinks, and nectars), and estimate the exposure of the Portuguese adolescent/adult population. ACE-K was found in 85.7% of the samples, in mean levels of 97.4 mg/L. ASP and SAC, detected in 37.5% and 33.9% of the samples, were found in averages of 161.5 and 55.0 mg/L, respectively. The maximum limits set for ASP were exceeded in one energy drink. SAC exceeded the maximum permitted level (MPL) level in 3 soft drinks based on tea extracts. In 4 samples SAC was found but not mentioned in the label, and in one of these samples exceeded the MPL. The estimated daily intake (EDI), calculated in mg per kilogram of body weight per day, of ACE-K, SAC and ASP was found to be below the acceptable daily intake (ADI), both for Portuguese adolescents and adult population. Traditional soft drinks accounted for the highest EDIs representing 1.8%, 2.3% and 0.6% for ACE-K, SAC and ASP, respectively, of the ADI. Considering the previous report in Portugal it is observed that the population is currently exposed to a greater amount of artificial sweeteners, which may indicate a trend for more artificial sweeteners' usage in order to reduce sugar intake.
