Why it’s in your food

The manufacturer’s reason.

Food manufacturers add riboflavin to fortify processed grains and cereals, helping to prevent vitamin B2 deficiencies. It can also impart a yellow color to certain products.

FAQ

Frequently asked questions.

Does riboflavin contribute to the color of food?▾
Yes, riboflavin is naturally a yellow compound. When added to foods for fortification, especially in higher concentrations, it can impart a yellow or greenish-yellow hue, which is sometimes noticeable in fortified breakfast cereals or vitamin supplements.
How is the riboflavin used in food typically made?▾
Most riboflavin used in food fortification is produced through large-scale industrial fermentation, where specific microorganisms like bacteria or fungi synthesize the vitamin. Alternatively, it can be made through multi-step chemical synthesis from simpler precursors.
Would a 1950s Italian grandmother recognize riboflavin?▾
Nonna would not recognize 'riboflavin' as a specific ingredient to add to her cooking. Her family would naturally obtain vitamin B2 from whole foods like milk, eggs, cheese, and leafy green vegetables that she regularly prepared.
