摘要： 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.

摘要： Precise control of hop aromatic flavors and hop bitter acids in beer is achieved by adsorbing these hop flavors on fumed silicon dioxide and dosing the fumed silicon dioxide containing adsorbed hop flavor into beer, preferably after suspending the fumed silicon dioxide containing the adsorbed flavors in an aqueous medium. The hop flavors are desorbed in the beer and fumed silicon dioxide solids become available as a clarifying agent and are subsquently filtered from the beer.

摘要： A novel method for the removal of hitherto unrecognized undesirable odor-forming impurities from hop flavors, including unreduced alpha and isoalpha acids and reduced alpha and isoalpha acids, by extracting the impurities from these flavors into water at a pH above 4, preferably above 6 or 7, with or without the presence of salt or solvent, and separating the aqueous phase containing the impurities from the purified hop flavor, as well as the important two-phase and salt-containing intermediate products and the final purified hop flavor which is essentially free of such 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.

摘要： A readily water-dispersible hop extract composition, consisting essentially of hop aroma and flavor components comprising at least 10% by weight of free fatty acid substances derived from hops, is useful to increase the utilization of the hop aroma and flavor components. It may be produced by treatment of an extract of hops with a lipase or with an excess of alkali. The starting hop extract, made conventionally as by extraction with organic solvent or supercritical carbon dioxide, preferably has alpha, isoalpha, and beta hop acids removed before treatment with excess alkali. A cosolvent, such as a lower alkanol, polyol, or wetting agent, heat, or high shear may be used to improve mixing of the lipidic organic phase of the hop extract with excess alkali. The water-dispersible lipidic hop extract imparts an enhanced hop aroma and flavor upon addition to the wort at some point during the brewing process between boiling and the beginning of fermentation. A beer incorporating the dispersible lipidic hop extract composition has a stronger hop aroma and flavor than beer incorporating the usual hop extract. The present application is directed to production of the readily-dispersible lipidic hop extract composition using lipase.

摘要： A process for making hexahydrolupulone is described which involves the separation of beta acids from a hop extract, the removal of catalyst poisons from the beta acids, the hydrogenation of the beta acids to hexahydrolupulone, and the purification of the resulting hexahydrolupulone. Its use as an inhibitor of the growth of unwanted types of cells is described, as well as preferred forms for such use.

摘要： This invention describes heretofore unknown forms of dihydro (DHIA) and hexahydro (HHIA) isoalpha acids having a high ratio of trans to cis isomers and a process for their production. Also, non-precipitating clear 5, 10, 20% and higher aqueous solutions thereof, since they are soluble at room temperature in soft water. This is due to the high ratio of trans to cis isomers. Unlike prior art essentially all cis isomer products, they remain haze free both at a neutral pH in water and at 1% to 2% and higher concentrations. This invention has the advantage over the prior art in that DHIA and HHIA can be provided as stable, non-separating liquids, at practical concentrations in the range of 5% to about 40%, which do not require heating to about 50° to 90° C. and above with stirring to effect dissolution of precipitates. The high trans products described herein can be admixed with isoalpha- and tetrahydro-isoalpha acids.

摘要： The present application discloses a novel and advantageous method for the preparation of essentially odor-free alkali metal tetrahydroisohumulate (THIH) which proceeds through isomerization of the essential alkali metal tetrahydrohumulate (THH) intermediate, which is in turn produced by the hydrogenation with two moles of hydrogen of a starting alkali metal humulate (H) at a pH of at least 10, the intermediate THH being thus produced with relative ease and in high yields and purity, which high yields and purity carry over to the ultimate end product, namely, to the essentially aroma-, odor-, and impurity-free THIH, which end product accordingly does not require steam-stripping or other cleanup procedure as is conventional for THIH produced from other sources or by other procedure.
