Artificial Colors

Also known as artificial colorants

What are artificial colors?

Artificial colors are food additives used to provide or enhance characteristic colors in food products. They are obtained from synthetic processes, and are typically made up of complex hydrocarbons, nitrogen and sulfur ions.¹  

Compared to naturally extracted colors, artificial colors are more stable, economical, and  available in a wider variety of colors. They are available in various forms: 

  • Liquid 
  • Liquid-gel
  • Gel-paste
  • Powder
  • Oil-based

Origin

The origin of food colorants dates back to 1500 BC. The production of synthetic colorants is attributed to William Henry Perkin, who in 1856 accidentally discovered aniline purple. Shortly after, food colorants became more common. By the 1900s, around 695 food colorants became available.¹

Due to current the current natural and clean label trend, artificial colorants are becoming less appealing to consumers.¹

Function

In baking, artificial colors are used to provide color to frostings, cake batters, breads, cookies, muffins and fillings.¹ Artificial colors are used in baked goods to:¹

Commercial production

Artificial colors are manufactured through the following process:3

Application

Two main categories of artificial colors are used in food production:

Artificial colors are used in the manufacture of several baked goods such as cakes, cookies, muffins and cupcakes. Also, they are common in the production of frostings, fillings and jellies.1,2

Some considerations when using artificial colorants:¹,²

A concentration of 1.5 – 3% of water-soluble colorant provides a good dough dispersion. Lakes are preferred due to their oil-soluble nature.1,2

Regulations

Currently, seven FDA-certified food colorants are permitted for  use in food products. Two other artificial colors (Orange B and Citrus Red #2) are approved for external use in particular food products.4

In the EU, color additives are regulated by the EC NO1333/2008.5

FDA approved artificial colors:1,2,4,5
