E106 - flavin mononucleotide

Origin

Flavin mononucleotide (FMN), also known as riboflavin-5'-phosphate, is a derivative of riboflavin (vitamin B2). It is produced through the enzymatic phosphorylation of riboflavin. FMN is a crucial coenzyme in various biological processes, particularly in redox reactions. It can be produced synthetically or derived from microbial fermentation.

Usage

In the food industry, FMN is used as a food coloring agent, providing a yellow-orange hue. Its primary application is in products where a stable and vibrant color is desired. It also functions as a nutrient supplement, contributing to the riboflavin content of the food. FMN is used in a variety of food products, including beverages, dairy products, and processed foods. Its use is limited by regulations in different countries, specifying maximum permitted levels.

Side Effects

FMN is generally considered safe for consumption at levels typically used in food. Riboflavin, the precursor to FMN, is an essential nutrient, and excess riboflavin is generally excreted in urine. However, very high doses of FMN might, theoretically, lead to gastrointestinal discomfort or other minor side effects, although such effects are rare. No significant adverse effects have been reported at levels used in food. The EFSA has established an Acceptable Daily Intake (ADI) for riboflavin (and by extension, FMN) as 'not limited', indicating a high margin of safety.

Regulatory Status

Flavin mononucleotide (E106) is approved for use as a food additive in several countries, including those within the European Union. Regulations specify the food categories in which it can be used and the maximum permitted levels. The regulatory status may vary in other countries, such as the United States, where it is generally recognized as safe (GRAS) under specific conditions of use.
