AS/LC-019 - Analysis Example of Cochineal Extract (Carminic Acid) in Food

Analysis Example of Cochineal Extract (Carminic Acid) in Food

Cochineal extract is a red dye containing carminic acid, a quinone pigment, as the main component and it is obtained from the cochineal insect (native to Central and South America). Cochineal extract is also found in the List of Existing Food Additives regulated by the Food Sanitation Law and is widely used in food, drugs, quasi-drugs, and cosmetics.

In the Standard Methods of Analysis for Hygienic Chemistry, TLC is specified as the test method for cochineal extract. However, the analysis method by HPLC is also introduced as a reference method.

Presented here is the analysis of carminic acid in food using HPLC-DAD under the specified analytical conditions. For the qualitative analysis of carminic acid, the DAD absorption spectrum, in addition to the peak retention time, is used for identity confirmation.
