PRODUCTION OF ISOMERIZED HOP PREPARATIONS

摘要

IMPROVEMENTS RELATING TO THE PRODUCTION OF BEER 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.degree.C in a closed vessel, thereby to form a hop preparation high in iso- ? -acids and with substantially undegraded hop oils. The closed vessel is preferably an extrusion cooker.
