Title: Innovations by Herbert L Grant in Hops Processing
Introduction
Herbert L Grant is an accomplished inventor based in Yakima, WA (US), known for his significant contributions to the field of hops processing. With a total of three patents to his name, Grant has developed innovative methods that enhance the brewing process, particularly focusing on the extraction and stabilization of alpha acids in hops.
Latest Patents
One of Grant's latest patents is titled "Mixed solvent extraction of hops." This patent describes an improved process for the selective extraction of alpha acids from hops using liquid carbon dioxide as a solvent. The solubility of these acids is enhanced by adding a minor amount of a selected organic substance that is non-reactive with the alpha acids and possesses specific physical properties. The preferred organic substance is a 1 to 4 carbon atom aliphatic alcohol, used in concentrations ranging from about 0.1 to about 30 volume percent.
Another notable patent is the "Method for processing hops for brewing." This method stabilizes hops and their alpha acids against deterioration and light sensitivity. The process involves isomerizing a substantial portion of the alpha acids and contacting the resulting iso-alpha acids with a metallic hydride compound suitable for food use. This innovative approach is particularly beneficial for pelletizing operations in the brewing industry.
