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.

E338 - Phosphoric acid

Phosphoric acid (E338) is a clear, tart-tasting acid used to control acidity and sharpen flavor in many foods and drinks. It also binds trace metals, which helps stop off-flavors and color changes. You’ll most often see it on the label of colas and other soft drinks.
