Iso-α-säuren/reduzierte Iso-α-säuren

Neben Iso-­α-säuren, die natürlicherweise beim Würzekochen entstehen, werden so genannte reduzierte Iso-α-säuren (Dihydro­iso-α-säuren [Rho­iso-α-säuren], Tetrahydro­iso-α-säuren und Hexahydro­iso-α-säuren) zur Bierbitterung eingesetzt. Während die Iso-α­säuren unter Lichteinfluss ein äusserst unangenehm riechendes Mercaptan bilden (Lichtgeschmack), sind die reduzierten Produkte stabil. Die Bestimmung der Iso-α-säuren erfolgt mit einer isokratischen HPLC­­Methode. Für die Analyse von Gemischen aus Iso-α-säuren und reduzierten Iso-α-säuren ist eine Gradientenelution erforderlich.
