Chinese Name: Edible carmine
The chemical name 1- (4'- sulfonate-1 '- naphthalazo) -2- naphthol -6,8- trisodium disulfonate is an isomer of amaranth. Cochineal red (Ponceau4R) is one of the most widely used monoazo synthetic pigments in China. In recent years, some reports pointed out that carmine with eu standards disable Sudan red I belongs to azo pigment, azo compound precursor can be metabolized in the body cause mutations in the original - aromatic amine compounds.
