Electromigration methods in the determination of synthetic food dyes

A disposable tartrazine sensor fabricated with a synchronously activated nanocomposite comprising gadolinium molybdate nanoflowers anchored on functionalized carbon nanofibers

“…Several analytical detection techniques have been established to detect and eliminate TRZ, which include thin-layer chromatography, 9 high-performance liquid chromatography, 10 capillary electrophoresis, 11 and spectrophotometry. Recently, chromatographic techniques have been integrated with other analytical tools to determine azo food dyes; for instance, LC-UV-Vis and LC-MS have been used to analyze various food matrices.…”

“…5 The European Food Safety Authority (EFSA) and the United States Food and Drug Administration restrict the concentration of azo food dyes in commercial products to ensure an innocuous supply to consumers.
