Özet
Their low toxicity, low-volume use, and, most importantly, excellent solubilisation properties have made deep eutectic solvents valuable and popular. This study aims to develop a new-generation, ultrasonic-assisted, green deep eutectic solvent-mediated microextraction procedure for the spectrophotometric determination of curcumin, a dye found in various food products. The method steps for the microextraction procedure were established by analysing the effects of numerous parameters. This method was applied to real samples of different brands and types of beverages, curry sauces, food supplements, and lozenges, and curcumin dye was detected in all six real samples. The determination of curcumin dye in the products used as real samples in this study was performed for the first time using the DES compound, formed by combining thymol and menthol in a 1:2 molar ratio. This demonstrates the study's innovative nature and its contribution to the literature. The optimal working range for the procedure is 10-4000 & micro;g L-1, the detection limit is 3.35 & micro;g L-1, and the quantification limit is 11.19 & micro;g L-1. The validity and accuracy of the procedure were also demonstrated by performing addition/recovery tests and intra- and inter-day sensitivity studies. Under ideal circumstances, the correlation coefficient (R2) was 0.9995; the extraction recoveries ranged from 95.03% to 103.77%; and the intra- and inter-day relative standard deviations (RSDs) were 4.07% and 4.59%, respectively. With a very high enrichment factor (125) and recovery values above 95%, this method has proven to be a dependable, highly sensitive, and innovative analytical method. These values demonstrate that the developed method has satisfactory accuracy and validity. The procedure developed for curcumin extraction from food samples is both innovative and environmentally friendly. The greenness of the method was also evaluated using the qualitative green assessment tool, including AGREEprep and BAGI.
