Article Abstract
A sulfonamide derivative synthesized from 1,8-naphthalimide-based amine and 4-methoxy-benzenesulfonyl chloride has been enwrapped into the micelles of a neutral surfactant TX-100 to form highly emissive nanomicelles MXL@TX- 100. The proposed sensor offered highly sensitive turn-off detection of Allura red (linear range = 0.66-224 µM) with the limit of detection (LOD) of 0.2 µM (R = 0.999) due to fluorescence resonance energy transfer from MXL@TX- 100 to Allura red. To the best of our knowledge, no organic compound-based sensor has been reported for the determination of Allura red so far. Additionally, nanomicelles MXL@TX- 100 were utilized for the sensing of picric acid (LOD = 0.92 µM, R = 0.998) in the linear range 3.03-928 µM. The binding constant between MXL@TX- 100-Allura red and MXL@TX- 100-picric were calculated to be 1.45 × 10 M and 1.97 × 10 M, respectively. Moreover, nanomicelles MXL@TX- 100 conveniently detected Allura red in real samples, viz. candy, soft drink, gulkand, and pharmaceutical syrup.

Food additives are chemical substances that are added to processed food to improve its flavor, texture, or appearance. Food additives can inhibit intestinal transporters, such as breast cancer resistance protein (BCRP), multidrug resistance associated protein 2 (MRP2), organic anion transporting polypeptide 2B1 (OATP2B1), and P-glycoprotein (P-gp). This inhibition could potentially affect the absorption of their substrate drugs and cause unwanted food-drug interactions.

This work investigated the effect of structural characteristics of five food dyes on adsorption onto chitosan-based biopolymeric sponges, using statistical physics models, experimental results, and FT-IR analyses to propose a detailed adsorption mechanism. Statistical physics models showed high predictive capacity. The multilayer model was the most effective for predicting the adsorption isotherms of the Indigo carmine, Allura red, and Amaranth.

For centuries, the practice of adding color to food has become deeply ingrained in culinary traditions, evolving into an indispensable aspect of food production today. Major food manufacturing companies extensively use colorants to enhance the visual appeal of their products. However, recent years have seen an increasing number of studies by researchers who have uncovered various health risks associated with food color additives.
