ABSTRACT:
A process for the removal of catalyst poisons from hops and hop extracts is disclosed. After processing the hops to extract the alpha or beta acids therein, the alpha or beta acids are treated with activated nickel catalyst. The activated nickel catalyst binds the catalyst poisons which are believed to be sulfur containing compounds. The activated nickel and catalyst poisons are separated from the alpha or beta acids, and the alpha or beta acids are then hydrogenated and isomerized into tetrahydroisoalpha acids.
