Illegal Dyes
Illegal dyes testing in Food, often referred to as colour additives, are commonly used in many of the foods we eat on regular basis. Artificial food dyes are responsible for the bright colours of candy, sports drinks and baked goods. They are added for a variety of reasons such as for
- Enhancing color
- Imparting flavor
- Increase shelf life of a product, and
- Making products more fun and appetizing.
- Attracting consumers
While many color additives used in food products are recognized as safe or GRAS (Generally Recognised as Safe), studies have reported that there are certain possible links between the consumption of foods containing dyes as an ingredient to increased hyperactivity in children.
List of illegal dyes include, but not limited to -
- Acid yellow 36 (Metanil Yellow)

Adverse Effects
Extensive research needs to be done on these illegal dyes to clear doubts related to their safety. Regulations are setting up maximum upper limits up to which a dye can be used in food products. Some illegal dyes are reported to be responsible for hyperactivity in children and much study is ongoing in this area.
Some dyes may also contain cancer causing components. A Detailed toxicological review is also provided for each dye in terms of both their genotoxic and carcinogenic properties.
