E106 – Riboflavin-5-Sodium Phosphate
ColouringDescription
Yellow-orange powder, synthesized from riboflavin (Vitamin B2) by phosphorylation with phosphorus oxychloride or other phosphorylating agents, followed by neutralization with sodium hydroxide
Notes
E106, also called riboflavin-5'-phosphate sodium, is created by chemically modifying vitamin B2 (riboflavin) through a process called phosphorylation, where a phosphate group is attached to the vitamin molecule. This modification makes the vitamin more stable and water-soluble than regular riboflavin. The process typically involves treating riboflavin with phosphoric acid compounds under controlled laboratory conditions to create this yellow-orange powder. This additive functions as both a nutritional supplement and a natural food coloring agent. It provides the same essential vitamin B2 benefits as regular riboflavin while giving foods an attractive golden-yellow color. You might find it in vitamin-fortified cereals, energy drinks, nutritional supplements, and processed foods where manufacturers want to add both nutritional value and appealing color. E106 is considered very safe since it's essentially a modified form of an essential vitamin that our bodies need for proper metabolism and energy production. It's suitable for vegetarians and vegans, and complies with most religious dietary requirements. Unlike synthetic artificial colors, this additive actually provides health benefits while enhancing food appearance, making it a preferred choice for health-conscious food manufacturers.
