Descripción

Descripción general

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

Aplicación

Carmoisine may be used as an analytical reference standard for the quantification of the analyte in the following:

• Food samples using spectrophotometric analysis technique.
• Sweets and beverages using differential pulse polarography.
• Synthetic mixtures and beverages using high performance liquid chromatography with diode array detection (HPLC-DAD).

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

Envase

Bottomless glass bottle. Contents are inside inserted fused cone.
