In this paper (purchase required) the authors developed an LC-MSMS method to identify and quantify fourteen illegal dyes in chili products, including chili powder, chili sauce, chili flavour, and snacks. They validated the method following the guidelines of CIR EU 2021/808 (the prescriptive requirements for methods for veterinary drug residues in animal products) at four concentration levels ranging from 5 to 70 µg/kg,. The method's applicability was further confirmed through successful proficiency testing (PT) participation.
An analysis of 2350 samples purchased on the Egyptian market over four years revealed that 18.62 % of chili powders, 14.05 % of sauces, 12.87 % of flavorus, and 11.32 % of snacks contained illegal dyes. Sudan IV and Red B were the most frequently found dyes in chili powders (15.86 % each), while Sudan I was the most common in sauces (13.72 %), flavours (12.54 %), and snacks (9.36 %).
