Isohumulones (iso-α-acids) form approximately 80%of the typical bitterness of beer. Their antimicrobial effect leads to a sterile beverage; their tensioactive character stabilizes the foam; and they have a major influence on the general flavor, smell, and smoothness of beer. HPLC represents the only analytical method that enables the specific quantitation of iso-α-acids in beer.
Thermo Scientific™ BeerNHop Solution provides a complete determination and quantitation of all major cis- and trans-isomer variants of iso-α-acids that are present.
The solution consists of a Thermo Scientific™ Dionex™ UltiMate™ 3000 system package and its related Thermo Scientific™ Isohumulones Starter Kit. System packages contain Thermo Scientific™ Dionex™ Chromeleon™ 7.2 Chromatography Data System software, as well as the Dionex UltiMate 3000 hardware needed to set up an entire UHPLC+-focused system for measuring the isohumulones. The starter kit provides all of the consumables, thereby the analysis can be started immediately. For more information, please download the BeerNHop Solution brochure or contact your local representative.
