“…Sudan dyes are widely applied in flavored beverages, which caused a lot of food safety problems (18). In addition, Sudan I may exist in drinks containing Sunset yellow because it is probably produced in Sunset yellow synthesis (19).…”

Edible colorants, as an important part of food additives, can not only enhance the sensorial attributes of foodstuffs, but can also increase one's appetite. They hold a very important position in food processing. In the past decades, the illegal addition of the inedible colorants has become one of the major issues of food safety. Industrial dyes, especially some azo dyes, are illegal additives frequently found in foodstuffs. They cannot provide any nutrients for the human body and even have toxicity, carcinogenic, or mutagenic effects, which may cause serious damage to consumers' health. There is an increasing demand to detect the inedible azo dyes in foodstuffs for health and safety reasons. In this review, the types and the physicochemical properties of the inedible azo dyes adulterated in foodstuffs and beverages are summarized, and the emphases are focused on the sample pretreatment methods and analytical techniques for monitoring of these dyes in foodstuffs and beverages.

“…In addition, SY and TZ could be oxidized electrochemically, a process that is accompanied by the release of electrons which could be correlated to the quantity of the electrolyzed colorant. The oxidation reactions of SY and TZ are presented in Figure 2 [10][11][12][13] . Electrochemical methods are simple, available, selective and convenient to use.…”

An electrochemical probe, highly sensitive for the detection of two colorants; sunset yellow (SY) and tartrazine (TZ), was examined. The probe was fabricated by modifying carbon electrodes with an iron-zirconium binary transition metal oxide, Fe2Zr2O7. In the presence of the oxide, SY and TZ exhibit well resolved oxidation peaks at 0.80 and 1.0 V, respectively, in pH 2.00 buffer solution. The developed method exhibits linear response in the range 1.9×10–5– 2.7×10–4 M for both SY and TZ. The corresponding limits of detection were found to be 5.7×10–6 M for SY and 1.3×10–5 M for TZ.
