  • Patent number: 6583322
    Abstract: 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.

  • Patent number: 6576134
    Abstract: A method of sample displacement chromatography separation which comprises applying a multicomponent sample to one end of a chromatography bed comprising stationary phase material having affinity for components of the sample, causing components of the sample to become distributed along the chromatography bed by passage over the bed of a non-eluting mobile solvent phase, and recovering a desired component of the sample from at lest a portion of the chromatography bed, in which the sample components are applied to the chromatography bed in a non-homogeneous manner such that the concentration of at least one component with relatively low affinity for the stationary phase material is enhanced during an earlier part of sample application and/or the concentration of at least one component with relatively high affinity for the stationary phase material is enhanced during a later part of sample application.
