E107 โ€” Yellow 2G

Yellow 2G is a synthetic azo dye used as a food coloring. It is considered very dangerous (Danger Level: 5) and has been banned or restricted in many countries due to health concerns, including its potential as a carcinogen. Yellow 2G does not offer any health benefits and is solely used to enhance the appearance of food products.

Purpose in Products

Yellow 2G was used to add a bright yellow color to food items such as candies, baked goods, and soft drinks. Its purpose was purely cosmetic, making foods appear more visually appealing.

Health Risks

  • Severe Health Concerns: Yellow 2G is linked to allergic reactions, including asthma and rashes, especially in sensitive individuals.
  • Carcinogenic Potential: Research suggests it may be a carcinogen, which has led to its prohibition in many countries.
  • Long-term exposure to synthetic azo dyes like E107 is associated with health risks, particularly affecting liver and kidney function.

Impact on Children

Children are especially vulnerable to the effects of Yellow 2G. Studies have linked azo dyes to hyperactivity and behavioral issues in children. These risks are a key reason for its regulatory bans.

Impact on Taste

Yellow 2G affects only the appearance of food and has no impact on taste or flavor.

Compatibility with Other Additives

Yellow 2G may interact negatively with other synthetic additives, potentially exacerbating health risks. Its combination with other azo dyes could intensify allergic reactions.

Natural Occurrence

Yellow 2G is not found in nature. It is entirely synthetic, manufactured using chemical processes involving azo compounds.

Production Process

The additive is produced synthetically through the combination of aromatic compounds and diazonium salts. These chemical reactions create the azo dye, which gives the distinctive yellow color.

Alternatives and Substitutes

Safer natural alternatives to Yellow 2G include:

  • Turmeric (E100): A natural yellow colorant derived from turmeric root.
  • Annatto (E160b): A plant-based colorant offering a similar shade.
  • Beet Juice: A vibrant red or yellow alternative that is entirely natural.

Regulation

Yellow 2G has been banned or restricted in many regions, including the European Union and the United States, due to its high danger level and carcinogenic potential. It is not approved for use in food products in these regions.

Conclusion

E107 (Yellow 2G) is a synthetic food dye with severe health risks, including allergies and potential carcinogenic effects. It has no nutritional or health benefits and is banned in most countries. Safer natural alternatives like turmeric and annatto are recommended for food coloring purposes.
