E101ii - Riboflavine-5′-phosphate

Origin

Riboflavin-5′-phosphate, also known as flavin mononucleotide (FMN), is a derivative of riboflavin (vitamin B2). It is produced through phosphorylation of riboflavin, often using enzymatic or chemical processes. It is found naturally in various foods and is also manufactured synthetically for use as a food additive. The synthetic production typically involves fermentation processes using microorganisms or chemical synthesis.

Usage

Riboflavin-5′-phosphate is primarily used as a food coloring agent, providing a yellow-orange hue. It is also used as a nutrient supplement, contributing to the vitamin B2 content of food products. It is commonly found in dairy products, cereals, sauces, and processed foods. As a food additive, it enhances the visual appeal of foods and beverages. Furthermore, it is used in pharmaceutical preparations and dietary supplements due to its vitamin B2 activity. It is water-soluble, making it suitable for use in aqueous solutions.

Side Effects

Riboflavin-5′-phosphate is generally considered safe for consumption. Riboflavin itself has a high safety profile, and excess amounts are typically excreted in urine. There are no significant side effects associated with its use as a food additive at permitted levels. The Acceptable Daily Intake (ADI) for riboflavin is considered 'not specified' by many regulatory bodies, indicating a very low risk of adverse effects. However, as with any food additive, some individuals may experience rare allergic reactions or sensitivities. High doses of riboflavin supplements may cause a yellow discoloration of urine, which is harmless.

Regulatory Status

Riboflavin-5′-phosphate is approved for use as a food additive in many countries, including the United States, the European Union, and Canada. In the EU, it is designated as E101ii. Regulatory bodies such as the European Food Safety Authority (EFSA) and the U.S. Food and Drug Administration (FDA) have evaluated its safety and established guidelines for its use in food products. It is subject to purity criteria and usage levels specified in food additive regulations.
