E151 – Brilliant Black BN

E151, known as Brilliant Black BN or Black PN, is a synthetic black azo dye used as a food coloring agent. It is highly soluble in water and imparts a black hue to various food and beverage products.

Purpose in Products

E151 is utilized to provide a black or dark brown color to consumables, enhancing their visual appeal. It is commonly found in products such as:

  • Confectionery: Licorice, candies, and desserts.
  • Beverages: Flavored drinks and soft drinks.
  • Sauces and Dressings: Brown sauce and other condiments.
  • Fish Products: Lumpfish caviar and fish paste.

Health Risks

E151 may cause adverse reactions in certain individuals:

  • Allergic Reactions: As an azo dye, it may elicit intolerance in people sensitive to salicylates, potentially causing skin rashes or itching.
  • Asthma: It is a histamine liberator and may intensify symptoms of asthma.
  • Hyperactivity in Children: In combination with benzoates, it is implicated in hyperactivity in children.
  • Intestinal Concerns: In the intestines, it can be transformed by bacteria into possibly hazardous compounds.

Impact on Children

E151 has been associated with hyperactivity and behavioral issues in children, especially when combined with certain preservatives like benzoates. Parents should monitor and limit the intake of foods containing this additive in children’s diets.

Impact on Taste

As a colorant, E151 has a neutral flavor profile and does not significantly alter the taste of the products to which it is added.

Compatibility with Other Additives

E151 can be combined with other synthetic dyes to achieve various color shades. However, mixing multiple synthetic dyes may have compounded health risks, particularly concerning hyperactivity in children when combined with preservatives like benzoates.

Natural Occurrence

E151 is not naturally occurring; it is synthesized from petroleum derivatives and classified as an azo dye.

Alternatives and Substitutes

Natural alternatives to E151 include:

  • Vegetable Carbon (E153): Provides a black color and is derived from natural sources like burnt vegetable matter.
  • Squid Ink: Offers a natural black pigment, commonly used in culinary applications, though less common in processed foods.

Regulation

E151 is approved for use in the European Union but has been banned in several countries, including the United States, Japan, and Norway, due to health concerns. The Acceptable Daily Intake (ADI) is set between 1-5 mg/kg body weight. Its use is subject to specific quantitative limits, and it is important to consult local regulations for permitted uses.

Conclusion

E151 (Brilliant Black BN) is a synthetic black dye used to color various food and beverage products. While it enhances visual appeal, it poses potential health risks, including allergic reactions and hyperactivity in children. Due to these concerns, it is banned in several countries. Natural alternatives like vegetable carbon are available and may be preferable for those seeking to avoid synthetic additives.
