Abstract
Two-phase and salt-containing intermediate products and the final purified hop flavor which is essentially free of impurities and which purified isoalpha acid or isohumulone will therefore not produce fruity, estery, sour aromas when used to flavor beverages, e.g., beer or ale, are disclosed. A rapid test for the detection of such aromas, involving dissolution of the hop flavor in ethanol at a concentration of one-half percent w/v and allowing the solution to stand for four days, allows accelerated determination of the presence or absence of such aromas and the odor-forming impurities which cause the undesirable odors.
