Red cabbage powder is made by extracting the flavin pigment from red cabbage leaves. This is usually done by boiling in an ethanol and water mixture, resulting in a deep-red/purple solution. This solution is then evaporated under reduced pressure and heat to yield a red/purple powder. The powder smells like cabbage, is soluble in water, and can be used as a dye or acid/base indicator. Many food manufacturers use red cabbage dye as a more 'natural' alternative to synthetic dyes, which are all suspected carcinogens.
