摘要： Disclosed is a water based method for extracting caffeine from alkaloid containing substances, in particular tea leaves. The method can be performed without the use of artificial substances. The method allows the other soluble, non-caffeine components of alkaloid containing substances to be part of the decaffeinated product, in particular, components such as catechins and antioxidants. Advantageously, the caffeine extracted from the alkaloid containing substances is reversibly adsorbed to an adsorbent and high percentile of the caffeine can be recovered from the adsorbent.

摘要： Tea extract is separated into a lighter colored and a darker colored phase by changing the natural self-separating capacity of the tea extract by concentrating the extract to 6-45 wt %, preferably 12-30 wt % solids, cooling the concentrate below 5.degree. C. and isolating the separated phases. The lighter colored phase is used in preparing clear cold-water soluble tea, reduced caffeine tea, isotonic tea. The darker colored phase may be used to prepare hot-water soluble instant tea, coloring agent, antioxidant or tea flavoring agent.

摘要： Coffee aroma gases are conveyed to a cryogenic collector in which liquid nitrogen is sprayed directly into the aroma gas stream to rapidly condense the aroma gas and form finely divided particles of coffee aroma frost suspended in a stream of nitrogen gas, while minimizing contact of the cooled gas with the walls of the collector. The suspension of aroma frost particles in gaseous nitrogen is passed through a tubular porous filter to remove the aroma frost particles which collect on the outer surface of the tubular filter, with the nitrogen gas passing through the porous filter and being exhausted from the collector. The porous filter is periodically back pulsed to dislodge aroma frost particles collected on the outer surface of the tubular filter, with the particles being recovered for incorporation in soluble coffee products.

摘要： The process disclosed herein decaffeinates an aqueous caffeine solution by contacting it with a solid caffeine adsorbent which is made more selective to caffeine by a thin layer of a water-immiscible, caffeine-specific solvent. The caffeine is selectively extracted from the aqueous solution, leaving the solubles necessary for a good tasting beverage, by the solid adsorbent. Because the solvent is selective, the coated adsorbent likewise shows selectivity.
