According to the wine quality and production conditions, the legislation in force states that masking defects and modifications of the wines by additions that determine changes in their taste, aroma and natural composition, can be a counterfeit product. This type of fraud is sanctioned according to the law. An example of these additives are synthetic sweeteners which, although they are forbidden, may be found in wines. Synthetic sweeteners consumption may affect the consumer health, and also the consumption of fraudulent sweetened wines can be a real danger for them. To avoid all of these inconveniences for consumers and for combating fraud in the wine sector, we can highlight the frequency of synthetic sweeteners in bottled wines with a suitable liquid chromatography method. This method establishes how to identify and quantify three of the most commonly used synthetic sweeteners (acesulfame K - E950, aspartame - E951 and saccharin - E954) that can be found in the wine matrix by ultra-performance liquid chromatography (UPLC) with UV detection. The method has selectivity, detection limit and quantification limit, linearity, precision (repeatability and reproducibility), accuracy (bias and recovery).
