Effects of iso-alpha-acids on rumen fermentation and comparison of microbial populations between rumens and continuous culture fermenters
… The first experiment examined the effects of iso-alpha-acids from Humulus lupulus (Hops) extract on rumen fermentation. Iso-alpha-acid extract (IE) was provided to continuous culture fermenters to supply 0 (CON), 600 (LOW), 1200 (MED) or 1800 mg of IE/kg of diet DM/day. There was no effect (P > …

Investigation of the hops α-acids isomerization and occurring losses of iso-α-acids during wort preparation in the brewhouse
… identify the substance, which binds hop bitter acids, especially iso-alpha-acids, even after wort boiling. In addition, parameter ranges that occur in a novel brewhouse concept and lie outside the conventional brewhouse range are considered. The test series demonstrated that different pH values …

A preliminary investigation of the chemistry of hops: Methods for extraction and alpha-acid isomerization kinetics
… especially the organic compounds known as -acids: humulone, cohumulone, and adhumulone. There are several known methods for the extraction of the -acids described here, with the highest yield of 37% on the lab scale from organic solvent extractions. During the brewing process, these …
