Overview

E100 - Curcumin

Curcumin (E100) is the bright yellow pigment found in turmeric. As a food additive, it is used mainly to give a warm yellow to yellow‑orange color to many foods and drinks. It is popular because it is plant‑derived and brings a familiar, appetizing hue.

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.
