Purpose and Function

Red 2G (E128) is a synthetic azo dye that was historically used to give a red color to various food products. It was commonly found in:

  • Meat products: Used to enhance the appearance of sausages and burgers by giving them a bright red color.
  • Bakery products: Found in some baked goods and confectioneries to achieve a red hue.

While Red 2G (E128) was once widely used, its safety has been called into question, leading to its prohibition in many regions.

Potential Risks and Side Effects

Red 2G (E128) has been linked to several health concerns, primarily due to its potential breakdown into aniline, a chemical known to have toxic effects. Key concerns include:

  • Carcinogenicity: One of the primary concerns regarding E128 is its potential to break down into aniline, which has been linked to carcinogenic effects in laboratory studies. Prolonged consumption of aniline is thought to increase the risk of cancer.
  • Allergic reactions: Like many synthetic azo dyes, Red 2G may cause allergic reactions in sensitive individuals, particularly those with asthma or sensitivity to certain food dyes. These reactions can range from skin rashes to respiratory issues.
  • Regulatory bans: Due to concerns about its potential carcinogenic effects, Red 2G (E128) has been banned in the European Union and many other countries. It is no longer permitted in food products.
