Curcumin

Curcumin is the main active compound found in turmeric, a spice derived from the root of the *Curcuma longa* plant. It is responsible for turmeric's vibrant yellow-orange color. Curcumin is typically extracted from turmeric using solvents and then purified.

Curcumin is primarily used as a natural yellow food coloring (E100) in a variety of products. It can be found in cheeses, yogurts, butter, and mustard. It is also used in some baked goods, confectionery, and beverages to impart a yellow hue.

In the US, curcumin is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. It is also approved as a food additive in the EU. JECFA has evaluated curcumin and established an acceptable daily intake. Research suggests curcumin has antioxidant and anti-inflammatory properties, but more studies are needed to confirm these effects in humans at typical dietary intake levels. Some studies have explored its potential therapeutic uses, but it is not approved as a drug.
