Carminic acid linked to silica nanoparticles as pigment/antioxidant bifunctional excipient for pharmaceutical emulsions
(MDPI, 2020)
The incorporation of pigments and natural polyphenols into inorganic matrices, resulting in a hybrid material that improves the resistance and chemical stability of the pigments and the antioxidant capacity of the materials, ...
Exploratory study on sequestration of some essential metals by indigo carmine food dye
(2010-10-01)
Indigo carmine forms a stable complex with different ions, and the stability constant of the complexes were evaluated as log K equal to 5.75; 5.00; 4.89 and 3.89 for complexes with Cu(II), Ni(II), Co(II) and Zn(II) ions, ...

Vibrational and electronic spectroscopic detection and quantification of carminic acid in candies
(Elsevier Ltd, 2019)
Carminic acid (CA) contained in one kind of gummy candy was detected and quantified by using vibrational and electronic spectroscopy, respectively; the proposed methodology in solution is simple and rapid without sample ...
Synthesis and sorption performance of highly specific imprinted particles for the direct recovery of carminic acid
(Elsevier, 2012-09)
Carminic acid (CA) is a colorant of natural origin, which is demanded by the food, cosmetic, and pharmaceutical industries. In this work, a selective finite bath process was developed based on the utilization of molecularly ...
Free radical scavenging capacity and antioxidant activity of cochineal (Dactylopius coccus C.) extracts
(Elsevier, 2010-03)
Carminic acid (CA) is a natural red pigment produced by Dactylopius coccus C. insects. It is widely used in the food industry to replace synthetic colourants. Despite being known for a long time, its antioxidant properties ...
