摘要： Unsaturated organic compounds, in particular .alpha.-acids and .beta.-acids, are purified prior to hydrogenation by mixing them with an adsorbent capable of adsorbing catalyst poisons, preferably activated carbon, and separating the adsorbent containing the catalyst poisons to recover the thus purified unsaturated organic compounds. A significant reduction in the use of hydrogenation catalyst is realized.

摘要： Disclosed are methods for the production of light stable hop products, useful for the brewing of beer or ale to be stored in clear or green glass containers, which beer or ale will not develop objectionable flavor as a result of exposure to light. Light stable hop products are prepared by double extraction of liquid/supercritical CO2 extracted hop solids with ethanol to remove alpha/iso-alpha-acids. Such alpha/iso-alpha-acids may be further removed from the ethanol extraction filtrate obtained in the double extraction process by subjecting such filtrate to an ion exchange medium, or precipitation by a metal ion, heavy metal ion, or alkali metal ion, or hydrogenation to provide an alpha/iso-alpha-acids free filtrate which may be added to the light stable double extracted hop solid residues obtained in the initial double extraction process.

摘要： Carbon dioxide is used as a reaction solvent in the hydrogenation of organic compounds. The carbon dioxide is preferably a liquid or a supercritical fluid. The hydrogenation method can be used advantageously in methods for making tetrahydroiso-alpha-acids from alpha-acids, iso-alpha-acids, or beta-acids. If beta-acids are used to make tetrahydroiso-alpha-acids, an acidic lower alcohol is preferably added to the carbon dioxide reaction medium to act as a promoter.

摘要： The isolation and characterization of a group of odorless and non-volatile glycosides from extracted hops (hop solids which have been previously extracted with non-polar solvents) is disclosed. These glycosides are water soluble and consist of a group of aromatic compounds conjugated to mono-, di-, and trisaccharides. These glycosides are responsible for the formation of kettle hop flavor and taste through both chemical and biological transformations. When these glycosides are transformed, they yield an essence and flavorant which imparts a kettle hop flavor and taste when the essence and flavorant is added to an unhopped beer. These kettle hop flavor essences and flavorants provide economy, consistency, flexibility, quality, and convenience to the brewing process because only one unhopped wort is required to brew a stock of unhopped beer. The unhopped beer can then be dosed with the desired amount of kettle hop flavor essence and flavorant.
摘要翻译： 公开了从提取的啤酒花中分离和表征一组无味和非挥发性糖苷（以前用非极性溶剂萃取的啤酒花固体）。 这些糖苷是水溶性的，并且由一组与单糖，二糖和三糖缀合的芳族化合物组成。 这些糖苷通过化学和生物转化都是形成壶啤酒花风味和味道的原因。 当这些糖苷被转化时，它们产生精华和调味剂，当将精华和调味剂加入到未煮熟的啤酒中时，其赋予壶啤酒花味和味道。 这些水壶啤酒风味香精和香料可以为酿造过程提供经济性，一致性，灵活性，质量和便利性，因为只需要一只未煮熟的麦汁来酿造未煮熟的啤酒。 然后可以将未煮过的啤酒加入所需量的壶啤酒香精精华和调味剂。

摘要： A method of preparing anactinic hop extracts comprising three stages: pre-purification of a liquid CO.sub.2 hop extract using liquid-liquid extraction to isolate pure humulones or alpha acids; isomerization/reduction of the humulones to obtain a mixture consisting of reduced isohumulones and non-isohumulone light unstable products (NILUPS); then adding alkali and water to the mixture of reduced isohumulones and NILUPS, heating and stirring to extract the reduced isohumulones into an aqueous phase and to leave the NILUPS in an oil phase. The aqueous phase is an anactinic hop extract which can be used to prepare light stable malt beverages.
