  • Removal of malic acid from coffee by fermentation
    Patent number: 5147666
    Abstract: Malic acid is removed from coffee to provide a coffee product which will evoke a decreased gastric acid response after ingestion. Malic acid is removed by malolactic fermentation of an aqueous coffee extract, which may be a green or brown extract. A malic acid-lean extract can be used to extract malic acid from coffee solids to produce demalated coffee solids. Demalation is preferably accomplished without removing excessive amounts of chlorogenic acid. Coffee products in accordance with the invention are preferably decaffeinated.
