A process for producing a liquid coffee concentrate that has a reduced acrylamide content. The process involves contacting a low aromatic aqueous coffee extract with a carbon and/or silica based resin with adsorptive function to reduce the acrylamide content of the extract, prior to combining the treated extract with a high aromatic aqueous coffee extract. In particular, the process comprises the steps of: a) providing a low aromatic aqueous coffee extract having a first acrylamide content; b) providing a high aromatic aqueous coffee extract; c) contacting the low aromatic aqueous coffee extract with a carbon and/or silica based resin with adsorptive function to provide a low aromatic aqueous coffee extract having a second acrylamide content; and d) combining the low aromatic aqueous coffee extract having a second acrylamide content and the high aromatic aqueous coffee extract to provide a liquid coffee concentrate, wherein the second acrylamide content is lower than the first acrylamide content.

The present invention relates to a dried coffee powder obtainable by a process comprising membrane filtration of a low temperature extract of roasted and ground coffee beans to reduce the concentration of low molecular weight components and drying the filtered coffee extract.

An apparatus and method for the removal of unwanted taste components from beverages is described. The apparatus provides a method for contacting a oleophilic-absorbing surface and/or hydrophobic-absorbing surface of polymer media with a beverage before, during or after it is dispensed so that undesirable flavors are selectively removed from the beverage without removing desirable flavors improving the enjoyment of its consumption.
