| Popis: | A simple and low-cost multipurpose analytical method using HPLC-UV-DAD was developed and validated, following international guidelines, for the determination of six synthetic food dyes: Tartrazine, Sunset Yellow, Amaranth, Allura Red, Indigotine, and Brilliant Blue. The method required a simple sample preparation step that consisted of dissolution or dilution of the samples in water, followed by pH adjustment and filtering through PVDF filters. No significant matrix effect was verified. Linear working ranges varied from 0.25 to 6.0 mg L−1. Appropriate limits of quantification (0.10 to 0.15 mg L−1), mean recoveries (90.2 to 106.6%), and repeatability and intermediate precision ( |
