Science / Chemistry / Extraction: A technique for separating components in a mixture that have different solubilities. For example, caffeine can be separated from coffee beans by washing the beans with supercritical fluid carbon dioxide; the caffeine dissolves in the carbon dioxide but flavor compounds do not. Vanillin can be extracted from vanilla beans by shaking the beans with an organic solvent, like ethanol.
Extraction Noun Synonyms: removal, extrication, withdrawal, uprooting, eradication, extirpation, deracination
Science / Chemistry / Solvent Extraction: Solvent extraction is a method for separating mixtures by exploiting differences in the solubilities of the components. For example, a coffee machine extracts the soluble components of ground coffee w MORE
Life Style / Wine / Cryo-Extraction: A process whereby grapes are frozen in order to extract ice, thereby concentrating the sugars, flavours and other components that remain. MORE
