Riboflavin, also known as vitamin B2 or lactoflavine, is a water-soluble vitamin used in food and beverage production as a yellow-orange colour. Under the E-number E101, it imparts a stable yellow hue to a range of products while also functioning as a nutrient in fortified foods. Its category, vitamin and mineral, reflects its role in enrichment and colouring, and it is authorised under Reg. 231/2012 and Reg. 1333/2008.
Manufacturers use riboflavin in beverages, dairy, cereals, and sauces where a yellow colour or vitamin fortification is needed. It is typically supplied as a crystalline powder, sparingly soluble in water, and is stable under normal processing conditions but sensitive to light. Formulators should store it protected from light and consider its solubility when incorporating it into liquid systems.
