Determination of carmine food dye (E120) in foodstuffs by stripping voltammetry.
J. AOAC Int. 92(5) , 1454-9, (2009) The behavior of the food colorant agent carmine (E120) was studied by square-wave adsorptive stripping voltammetry (SW-AdSV) at the hanging mercury drop electrode. It was observed that carmine gave a sensitive stripping voltammetric peak at -350 mV in pH 3 ac... |

[Absolute quantification of carminic acid in cochineal extract by quantitative NMR].
Shokuhin Eiseigaku Zasshi 51(1) , 19-27, (2010) A quantitative NMR (qNMR) method was applied for the determination of carminic acid. Carminic acid is the main component in cochineal dye that is widely used as a natural food colorant. Since several manufacturers only provide reagent-grade carminic acid, the... |

Controlling the bleeding of carmine colorant in crabstick.
J. Food Sci. 74(9) , C707-12, (2009) Carmine used to color surimi seafood often seeps or bleeds from red-colored meat to white meat when vacuum-packed products go through high-temperature long-time pasteurization. Various physical and chemical treatments were examined to investigate means to inh... |

Study on the fluorescence enhancement in Lanthanum(III)-carminic acid-cetyltrimethylammonium bromide system and its analytical application.
Spectrochim. Acta. A. Mol. Biomol. Spectrosc. 79(5) , 1946-51, (2011) A fluorescent enhancement system carminic acid (CA)-La3+-CTAB is found and based on this finding a new fluorimetric method for the determination of CA is developed. Under optimized conditions, the enhanced intensities of fluorescence are quantitatively in pro... |
