Analytical Standards for Food Color Additives

Neat Standards for Artificial and Natural Food Colors

Deuterated Internal Standards Food dyes are popular in the food industry and are used to make products appear fresher and healthier. They are also used to give colorless foodstuff a more characteristic appearance as well as to change the original colors to preferred artificial ones.

However, certain food coloring additives have been banned in many countries since they have been found to have a detrimental effect on consumers’ health. For precise detection of all regulated food color additives, Sigma-Aldrich offers a comprehensive range of standards, including neats and deuterated analytical standards.

Neat Standards for E Numbers

In the European Union, E numbers are used as codes for food color additives. E numbers 100-199 include not only artificial food colors derived from petroleum, but also natural additives originating from sources such as vegetables, insects, or mixtures made from natural foodstuffs. However, although some E number food dyes are not allowed in the EU and US, some are still used illicitly in food products. For a precise quality control of food products, Sigma-Aldrich provides a broad range of neat standards.

Deuterated Internal Standards for Artificial Food Color Additives

Our food dye standard portfolio includes deuterated internal standards of some banned food colors. These standards provide accurate detection, as they show an optimal mass unit difference between the analyte and the standard, which prevents interference. In order to guarantee that your products are free of illegal contaminants, we offer Leucomalachite Green, Malachite Green, and Sudan as deuterated neat standards in 10 mg bottles. We offer Sudan I-d5 dissolved in acetonitrile.
