Yellow 6 is a synthetic food colorant (food dye, food coloring) with a reddish-yellow hue used to color beverages, cereals bakery goods, confections, and ice cream.
It is also used to color dietary supplements, oral and externally applied drugs, cosmetics, and as a pigment in printing inks.
This dye is supplied in the form of orange-red crystals. Its common name is sunset yellow FCF and its molecular formula is C16H10N2Na2O7S2. It is permanently listed by the FDA as a certified food color additive.
Large scale production of sunset yellow started in the US in the 1920’s and it is now used worldwide.
The colorant is an azo dye. Azo compounds are formed from arenediazonium ions reacting with highly reactive aromatic compounds, in what is called a ‘diazo coupling reaction.’ Sunset yellow is one of the most widely used colorants in foods.
Yellow 6 is made in one of 3 ways:
- By diazotizing 4-aminobenzenesulfonic acid using hydrochloric acid and sodium nitrite or sulfuric acid and sodium nitrite. The diazo compound is then coupled with 6-hydroxy-2-naphthalene-sulfonic acid. The dye is isolated as the sodium salt and dried. The trisodium salt of 3-hydroxy-4-[(4- sulfophenyl)azo]-2,7-naphthalenedisulfonic acid may be blended with the principal color.
- Coupling of diazotized sulfanilic acid with 2-naphthol-6-sulfonic acid.
- Coupling of Sulphanilic acid + Schaeffer’s acid (diazotisation/azo coupling)
The health & food industry intentionally has very limited studies on the dangers of toxic food dyes and, then, uses the same excuse that not enough information is available to conclude whether these dyes are actually dangerous!
In other words, they avoid the study, and then they use the excuse that not enough studies have been conducted. What a world!
Food dyes Yellow 5 and Yellow 6 are called a slow death, so, justifiably, they are banned in Europe.
So,don’t eat this colored stuff that looks like food and TELL YOUR FRIENDS ABOUT IT.
