Overview

E101 - Riboflavin

Riboflavin (E101) is a yellow food color that also happens to be vitamin B2. It adds a warm yellow tint to foods and drinks, and it is widely used for both coloring and vitamin fortification. It occurs naturally in many foods and has a long record of safe use in the U.S. and EU.

E251 - Sodium nitrate

Sodium nitrate (E251) is a preservative used mainly in long-cured meats and a few traditional cheeses. In these foods, it acts as a slow source of nitrite, which helps keep the food safe and keeps the cured color and flavor. When used within regulations, it is considered safe for the general population.
