E105 - Festgelb AB

Origin

Fast Yellow AB, also known as Acid Yellow 36, is a synthetic azo dye. Azo dyes are characterized by the presence of one or more azo groups (-N=N-) in their molecular structure. Fast Yellow AB was primarily used as a food coloring agent, providing a bright yellow hue. Its synthesis involves chemical reactions to couple diazonium salts with aromatic compounds.

Usage

Fast Yellow AB was historically used to color a variety of food products, including sweets, beverages, and processed foods. It was valued for its ability to impart a strong, vibrant yellow color. However, due to health concerns, its use in food has been widely discontinued and is now largely prohibited in many countries. It also saw some use in textile dyeing and other industrial applications.

Side Effects

Fast Yellow AB has been associated with several adverse health effects. Studies have indicated that it may be carcinogenic, meaning it has the potential to cause cancer. Additionally, it has been linked to allergic reactions in some individuals. Due to these safety concerns, Fast Yellow AB is no longer permitted for use as a food additive in many regions, including the European Union and the United States. Its use is restricted or banned in many other countries as well. There is no established Acceptable Daily Intake (ADI) because its use in food is not considered safe.

Regulatory Status

The use of Fast Yellow AB as a food additive is either banned or severely restricted in most countries due to safety concerns. It is not approved for use in food in the European Union or the United States. Regulatory bodies such as the European Food Safety Authority (EFSA) and the Food and Drug Administration (FDA) have not established an ADI for Fast Yellow AB due to its potential health risks. Consumers should avoid products that list Fast Yellow AB as an ingredient.
