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 contacting an aqueous coffee extract, which may be a green or brown extract, with an ion exchange resin capable of exchanging malic acid in the extract. Demalation of a ready-to-drink coffee brew may be effected substantially immediately after preparation of the brew in a home brewer or the like. 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.

Abstract: A process for the extraction of cranberry presscake is disclosed which involves the steps of grinding the presscake, preferably with a filter aid like rice hulls, subjecting this mixture to water extraction, microfiltering the extract to remove colloidal high molecular weight components and passing the microfiltered extract through reverse osmosis to recover a red-colored solution.
