40. Synthetic dyes used in various industries, including food, textile, and petroleum, are potential pollutants for food and environmental samples, in particular natural water samples. Sudan dyes are a class of azo dyes. They have been illegally used as additives in food products to maintain their red–orange color and thus stimulate sales of these products in the market (Qiao et al., 2011, Rebane et al., 2010, Sun et al., 2007, Soylak et al., 2011a, Soylak et al., 2011b and Stiborova et al., 2002). Sudan dyes are thought to be carcinogenic yet have been determined as a contaminant in chili powder (Calbiani et al., 2004 and Liu et al., 2007).
