As a natural pigment, jujube red pigment has become a research hotspot. There have been reports on the extraction processability and stability, but the purification process is currently less involved in the ultrasonic extraction method to effectively accelerate the dissolution of the active components of natural products, but the extraction purity is low. The ion adsorption method has many physical and chemical properties, is insoluble in acid and alkali and organic solvents, has good selectivity, and is not affected by organic substances.
