    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: A method for preparing a hop acid mixture having an enantiomeric excess of a (+)-tetrahydro-α-acid is disclosed. In the method, a racemate of a tetrahydro-α-acid is contacted with an amine to form a precipitate having an enantiomeric excess of the (+)-tetrahydro-α-acid. A method for preparing a hop acid is also disclosed. In the method, a racemate of a tetrahydro-α-acid is contacted with an amine to form a precipitate comprising a (+)-tetrahydro-α-acid, and the (+)-tetrahydro-α-acid is isomerized to a hop acid selected from the group consisting of (+)-trans-tetrahydro-iso-α-acids, (−)-cis-tetrahydro-iso-α-acids, and mixtures thereof, and reduced to (+)-trans-hexahydroiso-α-acids and (−)-cis-hexahydroiso-α-acids. An additive for flavoring a malt beverage is also disclosed. The additive includes a bittering agent selected from the group consisting of (+)-trans-tetrahydro-iso-α-acids, (−)-cis-tetrahydro-iso-α-acids, (+)-trans-hexahydroiso-α-acids, (−)-cis-hexahydroiso-α-acids, and mixtures thereof.

    摘要: A method for reducing the amount of beverage soluble metal ions in a diatomaceous earth filter aid is disclosed. The beverage soluble metal ions can be copper and/or iron. In the method, the diatomaceous earth filter aid is contacted with a hop compound selected from iso-alpha-acids, dihydroiso-alpha-acids, tetrahydroiso-alpha-acids, hexahydroiso-alpha-acids, alpha-acids, and beta-acids. The diatomaceous earth filter aid can also be contacted with and an acid other than the hop compound such as phosphoric acid. The iso-alpha-acids, dihydroiso-alpha-acids, tetrahydroiso-alpha-acids, hexahydroiso-alpha-acids, alpha-acids, or beta-acids bind the copper and iron metal ions and/or change the form of copper and iron in diatomaceous earth so the copper and iron are rendered substantially insoluble in a beverage such as beer. A method for filtering a beverage using the treated diatomaceous earth filter aid is also disclosed. A method for increasing the flavor stability of a malt beverage filtered with a diatomaceous earth filter aid is also disclosed.
