摘要: A method of continuously decaffeinating moistened, green coffee solids with supercritical carbon dioxide. Moistened, green coffee beans are moved periodically through an extraction vessel and contacted with continuously flowing supercritical carbon dioxide which extracts caffeine from the moist, green coffee beans. Caffeine is removed from the supercritical carbon dioxide by counter-current contact with wash water in an open vessel. The caffeine-depleted supercritical carbon dioxide is recirculated back to the extraction vessel and the caffeine-bearing wash water is subjected to concentration by reverse osmosis. Acidic, substantially caffeine-free permeate is directed back to the extraction system as wash water, or to moisturize the green coffee beans prior to extraction, or both.

摘要: A process for preparing a spray-dried product for improving the rate of dissolution of the active ingredient. The process includes mixing a crystalline active ingredient, which has a dissolution rate in unstirred water at 25° C. of greater than 15 minutes at a concentration of 14 ppm of the active ingredient, with a starch derivative, a second carrier material, and optionally, xanthan gum, to form a suspension, dispersion or solution of the active ingredient; homogenizing the mixture at a pressure of at least 4000 psig (2.758×107 Pa); and spray-drying the homogenized mixture to provide a spray-dried active ingredient that has an increased dissolution rate in water compared to the unencapsulated active ingredient.

摘要: A method of extracting roasted and ground coffee is disclosed. Exraction water is fed to one end of an extraction vessel containing roasted and ground coffee, and coffee extract is with drawn from the other end. Flow of water to and from the vessel is intermittently halted, and extracted roasted and ground coffee is intermittently discharged from the vessel, while a portion of unextracted coffee is charged to the vessel at the other end. The movement of coffee in the extraction vessel is countercurrent relative to the flow of the extraction water. The method of the present invention is less complex, is more easily controlled, requires a lower capital investment and produces a more aromatic coffee extract of better flavor balance.

摘要: The process disclosed herein decaffeinates an aqueous caffeine feed solution by contacting it with a multi-phase extractant which comprises a continuous phase of a liquid, water-immiscible, caffeine-specific solvent and discontinuous aqueous phase dispersed therein. The caffeine is selectively extracted from the aqueous feed solution, leaving the solubles necessary for a good testing beverage due to the high combined selectivity of the extractant phases. Very low solvent-to-extract ratios are possible because the multi-phase extractant has a much improved partition coefficient as compared to the water-immiscible solvent.

摘要: 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.

摘要: 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.
