Yellow 2G

Yellow 2G is a synthetic food dye that belongs to the class of azo dyes. It is also known as Food Yellow 3, E107, and C.I. Food Yellow 3. Yellow 2G is used in a variety of food products to impart a yellow color. However, its use has been controversial due to potential health concerns.

History

Yellow 2G was first synthesized in the late 19th century as part of the development of synthetic dyes. It was initially used in textiles before being adopted for use in food products. The dye is produced through a chemical reaction between aniline, a compound derived from coal tar, and sulfanilic acid.

Use in Food Industry

Yellow 2G is used in a variety of food products, including beverages, candies, and baked goods. It is particularly popular in the confectionery industry due to its bright, vibrant color. However, its use is not universal, with some countries banning or restricting its use due to health concerns.

Health Concerns

There have been several studies investigating the potential health effects of Yellow 2G. Some studies have suggested that the dye may cause allergic reactions in some individuals, particularly those with a sensitivity to salicylates. Other studies have raised concerns about potential carcinogenic effects, although these findings have been disputed.

In 2007, a study published in The Lancet suggested a possible link between consumption of food dyes, including Yellow 2G, and increased hyperactivity in children. However, the European Food Safety Authority (EFSA) has stated that the evidence is inconclusive and has not recommended a ban on the dye.

Regulation

The use of Yellow 2G in food products is regulated by various national and international bodies. In the European Union, the dye is designated as E107 and is approved for use in certain food products. However, it is banned in several countries, including the United States, Canada, and Norway.
