  • The bitterness intensity of oxidized hop acids : humulinones and hulupones

    Creator:
    Algazzali, Victor Alexander
    Abstract:
    The goal of this research was to investigate the bitterness intensity of known hop acid oxidation products, humulinones and hulupones. This was carried out by first creating suitable extracts of humulinones and hulupones of high purity for sensory testing. Using previously established oxidation methods and the addition of preparative liquid...

  • Human bitterness detection thresholds of hop acids in beer and honey

    Creator:
    Kolpin, Kathryn M.
    Abstract:
    Alpha acids are found in the lupulin glands of hops cones. These acids have no bitterness of their own, but can be isomerized and subsequently hydrogenated to form bitter iso-α-acids and tetrahydroiso-α-acids respectively. Current literature values for the detection thresholds of iso-α-acid and tetrahydroiso-α-acid in lager beer have been reported...

  • The influence of polyphenols and humulinones on bitterness in dry-hopped beer

    Creator:
    Parkin, Ellen Jane
    Abstract:
    This research sought to determine the origin of bitterness as a result of dry-hopping. An unhopped ale was dry-hopped and examined in the controlled dry-hop experiment and commercial beers were examined for chemical changes from dry-hopping in the commercially dry-hopped beer survey. This thesis work suggested specific bitter hop components...
