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
Hop isomerization in the brewhouse is subject to a variety of influences. For breweries it is important to know these influencing factors in order to avoid using an unnecessary amount of hops and thus to save raw material. The aim of the present dissertation is to clarify these factors in their …

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 …
