General description

Carmoisine is a synthetic azo dye, commonly added to food, beverages, medicine, and cosmetics.[1] It is frequently used alone or in combination with Allura red (E 129) and Ponceau 4R synthetic dyes.[2] It is reported to be used for purposes where the food needs to be heat-treated post-fermentation.[3]

Application

Carmoisine may be used as an analytical reference standard for the quantification of the analyte in the following:
  • Food samples using spectrophotometric analysis technique.[1]
  • Sweets and beverages using differential pulse polarography.[2]
  • Synthetic mixtures and beverages using high performance liquid chromatography with diode array detection (HPLC-DAD).[4]

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
