So, what is riboflavin-5-sodium phosphate?
Riboflavin-5-sodium phosphate, also known as food additive E101(ii), is a water-soluble derivative of riboflavin (vitamin B2) used as a yellow-orange coloring agent and a nutrient fortifier. It frequently appears in processed foods such as breakfast cereals, fortified beverages, baked goods, sauces, and infant nutrition products.
Manufacturers produce this substance by chemically phosphorylating riboflavin and neutralizing it into a stable sodium salt. The precursor riboflavin is almost universally generated through the microbial fermentation of plant-derived sugars using non-animal microorganisms like Ashbya gossypii, or through standard chemical synthesis. The subsequent phosphorylation step utilizes mineral-derived phosphates and synthetic reagents rather than animal inputs.
The verdict is vegan because riboflavin-5-sodium phosphate is derived entirely from microbial, mineral, or synthetic sources. No animal tissues, fluids, or animal-derived processing aids are utilized during its fermentation, synthesis, or chemical refinement.
How to quickly find the source of ingredients like riboflavin-5-sodium phosphate?
