Rhodamine B, an alkaline industrial dye, was forbidden in food due to its potential carcinogenicity to humans. However, some unscrupulous merchants often used it as a food colouring agent to dope chili oil. In this research, a microplate reader was utilized for rapid qualitative detection of rhodamine B in chili oil with the deep eutectic solvent which was comprised of choline chloride and ethylene glycol (mole ratio 1:3) as an extraction medium.
