Turmeric has been used as a spice, and also as a colorant, for centuries. It is known for its characteristic bright yellow shade. Turmeric has been known to provide many health benefits for years, whether being used for its medicinal benefits even as a simple home remedy, or more recently, having been scientifically shown to provide cardiovascular and anticarcinogenic benefits, due to its high antioxidative content and properties.
The coloring component for turmeric is known as Curcumin. The pigment is extracted from the root Curcuma Longa, which is cultivated primarily in India. Turmeric provides very bright yellow shades in many applications, including bakery, confectionery, dairy, and many prepared foods.
The market forms available include the insoluble pigment, oleoresins, and emulsion and encapsulated forms, both in powder and in liquid forms. Turmeric is known to have excellent heat stability, but it may be unstable when exposed to light in some applications. Specialized formulations are available to provide the additional stability requirements needed for many of these applications.

Annatto has been used for centuries throughout Latin American countries both as a colorant in foods, and also as a seasoning, also known as “achiote”, to provide an earthy flavor note to many customary cuisines. Historically it was used for body painting and coloring one’s face. As it was also used for treating health disorders and ailments, such as heartburn and nausea, it has now been scientifically shown to provide many health benefits, as an anticarcinogen, antimicrobial, antioxidant and anti-inflammatory.
Annatto is grown and harvested in South America, Africa and the Caribbean, from the seeds of the Bixa Orellana L. shrub. The pigment naturally occurs as the oil soluble form, as Bixin, a carotenoid, and is extracted from the exterior of the seeds. The water soluble form is generated using a simple processing step to create Norbixin, which is used widely in water based applications, including cheese and other dairy applications.
Annatto, as either Bixin or as Norbixin, has good to fair stability in most applications. It provides golden yellow to yellowish-orange shades when used. It is available as oil based systems, water soluble forms, acid stable forms, or as emulsified or encapsulated forms, for additional functionality and stability.

Beta Carotene is a carotenoid which is found in many vegetables and fruits. Carotenoids are a group of naturally derived colors found mostly in plants, algae, fungi and bacteria, providing the characteristic, and often bright colors we see in nature.
Sources rich in beta carotene include sweet potatoes, carrots, squash, cantaloupe, apricots and broccoli. However, most of the beta carotene which is used as a colorant in typical food and pharmaceutical applications is what is known as the “Nature Identical” form.
Beta Carotene is one of the first Exempt Colors which was approved and is now regulated and listed as “Nature Identical”, meaning that it is a synthetically produced form which is literally identical to the form found in nature, in vegetables and fruits. Beta carotene is also derived from natural sources, including the fungal form Blakeslea trispora and the algal form, from Dunaliella salina. Any form that is used in the US must meet the FDA specifications.
Beta carotene is oil soluble in its inherent state, as is true with all carotenoids, and can be used for oil based applications, like popcorn oils and spreads. It can also be emulsified or encapsulated, in order to provide a wide shade range, from bright yellow, to egg-shade yellow and deep reddish-orange shades, depending on both the formulation and the application. The formulation is critical in determining both the color stability and shade that will be provided in the final application.
These water miscible and water dispersible forms may be used for coloring beverages, confectionary, dairy and other water based applications.
