Zusammenfassung:A method for the production of isomerized hop preparations comprising admixing whole or powdered hops with a solid or aqueous alkali or alkaline earth metal salt. The invention provides that the resultant admixture is simultaneously subjected to a pressure of at least 2 Kg/cm2 and at a temperature of at least 80 DEG C. in a closed vessel, thereby to form a hop preparation high in iso- alpha -acids and with substantially undegraded hop oils. The closed vessel is preferably an extrusion cooker.
