Abstract
The invention relates to a method for extraction into an aqueous medium of hop acids from a hop acids containing matter and for dissolution in an aqueous medium of hop acids, comprising contacting a hop acids containing matter with carbon-containing chemical substances having at least one functional group containing a nitrogen atom with a lone electron pair and at least one other polar and/or hydrophilic functional group, thereby forming complexes of hop acids with the carbon-containing chemical substances with at least one functional group containing a nitrogen atom with a lone electron pair and at least one other polar and/or hydrophilic functional group. The present invention further relates to a method for preparing a brewed beverage, particularly for brewing a beer, and in particular to a method to improve the utilization of hop acids, including alpha-acids and iso-alpha-acids, in the brewing process.
