Abstract
1413797 Soluble coffee extract STRUTHERS SCIENTIFIC & INTERNATIONAL CORP 4 Jan 1973 [5 Jan 1972] 361/72 Heading A2B Caffeine is a solvent extracted and separated from green coffee beans, which beans are thereafter roasted and extracted with water, after which carcinogens are removed from the aqueous extract, by allowing the extract to stand at below 40‹F for 1-10 hrs and removing the carcinogen-bearing precipitate which forms by centrifuging, and the caffeine previously solvent extracted is then added to the extract, from which solid coffee may be recovered, as by spray drying or freeze concentration followed by freeze drying. A suitable apparatus comprises means for extracting caffeine from green beans, means for drying and roasting the beans, means for extraction with water under pressure, means for removing the precipitate from the resultant extract, means for adding caffeine to the precipitate free extract, and means for concentrating the extract.
