Abstract:

The inventive anthocyantin coloring agent and the method for the production thereof from organic matter relate to the food industry. Said natural coloring agent comprises glycosides cyanidine, glycoside pyonidine, organic matter, mineral salts and glycoside pelargonidine with the following component ratio, expressed in mass %: glycoside cyanidine between 0.1 and 8.6; glycoside pyonidine between 0.08 and 6.45; glycoside pelargonidine between 0.05 and 4.3; organic matter and mineral salts make up the rest. The inventive method for producing the coloring agent consists in the following elements: a pre-dry anthocyantin-containing corn is beaten, infused in an extract solution and extracted with the aid of a mixture of water solution of chlorohydric and citric acids in the context of ultrasonic vibrations. Afterwards, the coloring agent is filtrated and concentrated in vacuum. The extraction can be carried out in three steps.
