Abstract
The process for producing hulupones by oxidation of lupulones, using an oxygen-containing gas, in a substantially aqueous, alkaline reaction medium is improved by carrying out the reaction using conditions under which the hulupones precipitate from the reaction medium as a salt, and are then recovered from the reaction medium as a salt. Hulupones are known substances which can be used as bittering agents, particularly in the brewing industry.
