Why do emulsions form during extraction of caffeine?
Emulsions form during the extraction of caffeine due to the mixing of two immiscible liquids, typically water and an organic solvent. When these liquids are agitated, small droplets of one liquid disperse within the other, leading to a mixture that can stabilize colloidal particles. This instability often arises from the presence of surfactants or impurities that lower the interfacial tension, making it easier for the droplets to coalesce. As a result, emulsions can complicate the separation of caffeine from the extraction mixture.
