Latest Patents

Wheldon's latest patents include innovative methods for producing iso-.alpha.-acid preparations from hops. One method describes a process for extracting a high-quality primary extract containing .alpha.-acids from hops using liquid CO.sub.2. This extraction is performed at a sub-critical temperature of not less than -5°C. The primary extract contains .alpha.-acids, .beta.-acids, hop oil, and usually no significant amounts of other organic compounds originating from the hops. The isomerization of the .alpha.-acids in the primary extract is performed by boiling an alkaline solution, which can also help remove hop oil. Additionally, Wheldon has developed a method for preparing hop extracts by passing liquid carbon dioxide through a column of hop material at temperatures ranging from -5°C to +15°C. This method yields a primary extract of much higher purity compared to commercially available solvent extracts.
