This research highlights the application of a supramolecular solvent (SUPRAS) in a novel preconcentration procedure. The distinct properties and behavior of this SUPRAS enhance extraction capacity, allowing for better monitoring of curcumin levels in food samples. Critical process parameters were examined and optimized via multivariate methods to improve the efficiency of curcumin assessment.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Optimal data in curcumin estimation were determined: vortex time of 1.5\u2009min, salt dosage of 3.2% (w\/v), pH\u20095.6 solution and 197\u2009\u03bcL of extraction solvent. The predicted data agree with the measured data, and the observed validation error, ranging from 0.78% to 3.14%, remains within statistically acceptable thresholds, indicating model robustness. The detection limit was 2.4\u2009\u03bcg\u2009L<jats:sup>\u22121<\/jats:sup>, and the linear range for detection was determined to be 8\u2013600\u2009\u03bcg\u2009L<jats:sup>\u22121<\/jats:sup>. Various food samples were analyzed using the proposed model, demonstrating acceptable extraction efficiency and validating the model's accuracy.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>A rapid, sensitive, cost\u2010effective and straightforward method based on a microextraction supramolecular solvent model has been expanded for detecting curcumin in food samples.
