This work presents an on-line fluorescence method for the allura red (AR) determination. The is based on quenching of dots MoS2 because their interaction with non-fluorescence dye. MoS2-dots were synthetized and characterized by spectroscopic techniques High Resolution Transmission Electronic Microscopy (HR-TEM). simultaneous injection nanomaterial dye in a flow analysis system allows determina...

Direct selective detection of erythrosine in saffron in the presence of other synthetic dyes considers its fluorescence at 532 nm excitation/548 nm emission. Saffron pre-treatment was according to the ISO 3632-2 trade standard test methods. On account of calculated quantum yield values, none of the yellow dyes is expected to interfere. Among red ones, reservations about allura red AC, azorubine...

This paper reports the application of hydrophobic deep eutectic solvents (HDES) as an environmentally friendly alternative for liquid-phase microextraction (LPME) Allura Red AC and Tartrazine in food products spectrophotometric determination these analytes. The HDES used this work were prepared by mixing octanoic acid (OctAc) or decanoic (DecAc) tetrabutylammonium bromide (N4444-Br) a molar rat...

Food colors are considered the most important component of foodstuff for enhancing aesthetic appeal products. The rapid increase in population raised demand food materials, while wastewater from as-related processing industries is used irrigation. This study was conducted to examine genotoxicity industrial on plant growth-promoting rhizobacteria (PGPR). Three predominantly synthetic colors, inc...

Abstract Amaranth imprinted nanoparticles were prepared by two-phase mini emulsion polymerization of hydroxyethyl methacrylate and ethylene glycol dimethacrylate using acrylamide methacrylic acid as functional monomers. The amaranth non-imprinted nanoparticle was with the same procedure without amaranth. attached on chip surface modified allyl mercaptan. surfaces plasmon resonance (SPR) sensor ...

The food industry relies heavily on the incorporation of artificial pigments as additives, which significantly influences market demand.
