ABSTRACT:
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 CO2extracted 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.
