How do you separate a dye suspected to have contaminated a sample of orange juice?

To separate a dye suspected to have contaminated a sample of Orange Juice, you can use liquid-liquid extraction or chromatography techniques. Liquid-liquid extraction involves adding a solvent that selectively dissolves the dye, allowing it to be separated from the juice. Alternatively, thin-layer chromatography (TLC) can be used to separate the components based on their affinities for a stationary phase and a mobile phase, allowing you to identify and isolate the dye. After separation, further analysis can be conducted to confirm the identity of the dye.
