摘要

Beta acids, separated from hop extracts, are purified prior to hydrogenolysis by mixing with an aqueous solution of polyvalent metal ions, preferably edible ions such as magnesium or calcium ions, separating the aqueous beta acids from insoluble materials containing catalyst poisons, and recovering the thus-purified beta acids which are catalyst-poison free and in a form suitable for hydrogenolysis to 4-desoxy alpha acids.
