dc.description.abstractSmartphone digital image colorimetry, coupled with a deep eutectic solvent-based liquid-liquid microextraction, was used to determine the Brilliant Blue FCF colorant in energy drinks. The Brilliant Blue FCF determination using the smartphone digital image colorimetry (SDIC) method offers several advantages, including fast and practical application, low cost, and high efficiency. Colorimetric determinations were performed using the “RGB Color Detector” application. DES was obtained by mixing tetrabutylammonium chloride (TBAC) with decanoic acid (DecA) in a 1:2 ratio. The optimum conditions for microextraction were a pH of 5.0, a DES volume of 300 μL, a sample volume of 15 mL, an ultrasonic time of 2 min, and a centrifuging time of 3 min at 4000 rpm. The LOD and LOQ values for the technique were determined to be 0.001 μg mL−1 and 0.003 μg mL−1, respectively. The RSD was determined to be 2.54 % for intraday measurements and 3.04 % for interday measurements. The correlation coefficient was 0.9996, indicating that acceptable linearity was attained. Additionally, the developed microextraction method has been demonstrated to comply with green chemistry principles by applying the Green Analytical Procedure Index (GAPI) tool. © 2025 Elsevier B.V., All rights reserved.en_US
