摘要： A process for producing decaffeinated green coffee beans, decaffeinated roasted coffee beans or preparations produced therefrom is described, wherein one process step comprises the PEF (pulsed electric field) treatment of (optionally presoaked) green coffee beans. Also described is a decaffeinated green coffee bean, a decaffeinated roasted coffee bean, and a preparation produced therefrom, and also the use of a PEF device for the treatment of (optionally presoaked) green coffee beans. A system for decaffeinating green coffee beans is additionally described.

摘要： A process and apparatus for extracting ingredient substances from natural products by means of a pressurized fluid, particularly for decaffeinating tea leaves by means of carbon dioxide, wherein the ingredient substances are bound by an adsorbent, preferably activated carbon. The fluid is conducted through a product layer, the thickness of which in flow direction is small in comparision with that transversely of the flow direction and the fluid is passed through the product layer with changing, especially increasing, velocity. The apparatus includes a cylindrical high-pressure vessel with annular cylindrical baskets for accommodating the natural product and/or the adsorbent, and the gas flows from a cylindrical outer range to a cylindrical inner range. The time required for the treatment of leafy natural product is reduced, the flow paths of the fluid are shortened, thus diminishing the risk of clogging, and the fluid flow velocity is reduced.

摘要： A simple, reliable process for decaffeinating green coffee beans to a high degree while avoiding denaturation of the green coffee beans includes wetting the green coffee beans to a high water content of 35-50%-wt.; compressing the beans in a pressure chamber for a period of a few minutes to several hours in an atmosphere comprised of a supercritical fluid which is a gas at STP, at a temperature ranging from 20.degree. to 80.degree. C. under a critical pressure ranging from 75 to 300 bar; decompressing the wetted beans from critical pressure p.sub.c to a pressure p for which p.sub.c .ltoreq.p.ltoreq.1 bar abruptly or in the space of a few minutes, while avoiding freezing the green coffee beans; washing with water or with the supercritical fluid for selective extraction of the caffeine; repeating the process one or more times; centrifuging; drying; and roasting the beans. Further, caffeine is recovered in a known manner from the washing medium.

摘要： Liquid propane, liquid butane or mixtures thereof at a temperature of from 30.degree. C. to 95.degree. C. is employed to selectively remove caffeine from moistened green coffee. The resulting decaffeinated coffee is then roasted and processed to ground or soluble coffee products which will possess the flavor and aroma of comparable non-decaffeinated coffee products.
