Abstract
314,059. Klapproth, W. June 22, 1928, [Convention date]. Coffee preparations.-A process for the preparation of substantially caffeine-free coffee consists in extracting the caffeine from the beans with water which has previously been enriched with the extractive substances such as sugar, tannin, &c. contained in the beans. The extractive solution is obtained by treating coffee beans with warm or cold water, and then treating the aqueous extract with a solvent for the dissolved caffeine, such as benzol or chloroform. The caffeine-free aqueous solution is then used to treat a fresh supply of beans. It is stated that an aqueous extractive solution so prepared removes only caffeine when applied to fresh coffee beans.
