Abstract
A method of preparing anactinic hop extracts comprising three stages: pre-purification of a liquid CO.sub.2 hop extract using liquid-liquid extraction to isolate pure humulones or alpha acids; isomerization/reduction of the humulones to obtain a mixture consisting of reduced isohumulones and non-isohumulone light unstable products (NILUPS); then adding alkali and water to the mixture of reduced isohumulones and NILUPS, heating and stirring to extract the reduced isohumulones into an aqueous phase and to leave the NILUPS in an oil phase. The aqueous phase is an anactinic hop extract which can be used to prepare light stable malt beverages.
