Seven dyes were initially approved under the Pure Food and Drug Act of 1906, but several have been delisted and replacements have been found. [3]
[edit]Current seven
In the USA, the following seven artificial colorings are permitted in food (the most common in bold) as of 2007:
- FD&C Blue No. 1 – Brilliant Blue FCF, E133 (blue shade)
- FD&C Blue No. 2 – Indigotine, E132 (indigo shade)
- FD&C Green No. 3 – Fast Green FCF, E143 (turquoise shade)
- FD&C Red No. 40 – Allura Red AC, E129 (red shade)
- FD&C Red No. 3 – Erythrosine, E127 (pink shade, commonly used in glacé cherries) [4]
- FD&C Yellow No. 5 – Tartrazine, E102 (yellow shade)
- FD&C Yellow No. 6 – Sunset Yellow FCF, E110 (orange shade)
The above are known as "primary colors"; when they are mixed to produce other colors, those colors are then known as "secondary colors".
