Quinoline yellow, Quinoline Yellow WS, C.I. 47005, or Food Yellow 13, is a yellow food dye with a maximum absorption wavelength of 416 nm.[3]p. 119 Chemically it is a mixture of disulfonates (principally), monosulfonates and trisulfonates of 2-(2-quinolyl) indan-1,3-dione.

The color Quinoline Yellow SS (Spirit Soluble), which lacks the sulfonate groups, is a related form that is insoluble in water.

Uses

Quinoline Yellow is used as a greenish yellow food additive in certain countries, designated in Europe as the E number E104.[4] In the EU and Australia, Quinoline Yellow is permitted in beverages and is used in foods, like sauces, decorations, and coatings; Quinoline Yellow is not listed as a permitted food additive in Canada or the US, where it is permitted in medicines and cosmetics and is known as D&C Yellow 10.[5]:461 The Codex Alimentarius does not list it.[5]:461

Health effects

Quinolone Yellow WS has not been associated with any significant long-term toxicity, is not genotoxic or carcinogenic and there is no evidence of adverse effects on reproduction or development.[5]:461–463

Possible cause of hyperactivity

Since the 1970s and the well-publicized advocacy of Benjamin Feingold, there has been public concern that food colorings may cause ADHD-like behavior in children.[6] These concerns have led the FDA and other food safety authorities to regularly review the scientific literature, and led the UK FSA to commission a study by researchers at Southampton University of the effect of a mixture of six food dyes (Tartrazine, Allura Red, Ponceau 4R, Quinoline Yellow WS, Sunset Yellow FCF and Carmoisine (dubbed the "Southampton 6")) and sodium benzoate (a preservative) on children in the general population, who consumed them in beverages; the study published in 2007.[6][7] The study found "a possible link between the consumption of these artificial colours and a sodium benzoate preservative and increased hyperactivity" in the children;[6][7] the advisory committee to the FSA that evaluated the study also determined that because of study limitations, the results could not be extrapolated to the general population, and further testing was recommended".[6]

The European regulatory community, with a stronger emphasis on the precautionary principle, required labelling and temporarily reduced the acceptable daily intake (ADI) for the food colorings; the UK FSA called for voluntary withdrawal of the colorings by food manufacturers.[6][7] However in 2009 the EFSA re-evaluated the data at hand and determined that "the available scientific evidence does not substantiate a link between the color additives and behavioral effects".[6][8] On the basis of other evidence the EFSA also reduced the acceptable daily intake (ADI) to 0.5 mg/kg.

The US FDA did not make changes following the publication of the Southampton study, but following a citizen petition filed by the Center for Science in the Public Interest in 2008, requesting the FDA ban several food additives, the FDA commenced a review of the available evidence, and still made no changes.[6]

There is no evidence to support broad claims that food coloring causes food intolerance and ADHD-like behavior in children.[9]:452 It is possible that certain food coloring may act as a trigger in those who are genetically predisposed, but the evidence is weak.[6][10]
