Abstract
314,308. Neustadt, G., and Neustadt, I. June 22, 1928,. [Convention date]. Coffee preparations.-Extracted and decaffeinized coffee beans are enriched by a caffeine-free extract obtained in a similar manner from a larger quantity of coffee beans, or coffee substitutes in order that the extractive matter in the treated beans may correspond to the extractive content of the untreated beans. The beans are first treated with water from 60-90‹ C. and the extract withdrawn. They are then treated with wet steam, the condensate being continually removed. A thickened neutral extract is next added and the drum rotated and heated, from 60-90‹ C. The remaining extract is then withdrawn and the beans washed and dried, so that their weight corresponds to their original weight. The first extract is freed from caffeine and added to the extract residue, and concentrated ready for a second batch. A small percentage of beans may be withdrawn before the thickened extract is added, and treated with extract to form inferior coffee or coffee substitute.
