Definitions
- the present invention is related to a novel, alternative, low-cost process for the production of carminic acid (CA) in vitro, for use in the dye industry that has wide application in the food, cosmetic, pharmaceutical and industrial industries. textile, among others.
- CA carminic acid
- the content of carminic acid present in each sample was determined by high performance liquid chromatography.
- the extraction of the pigment from the samples was carried out with a 2M HCl solution.
- the detection limits of the pigment were from 1 .0 mg L-1 to 120.0 mg L-1 .
- No significant effect of pH on carminic acid content or number of cell lines was observed, although the intermediate pH (5.5) tended to give better results.
- the conclusions of said document indicate that “culture media with 4.5 to 6.5 are suitable for the in vitro culture of cochineal cells, although intermediate pHs tended to be better in terms of carmine content and the number of cell lines. Centrifugation times of 2 and 5 min were the most suitable for establishing D. coccus embryo cell lines. Carmine production in secondary cultures was low, so it was suggested to evaluate other variables of the culture medium, such as osmotic pressure and constituents of the nutrient medium, mainly.
