New analytical method for determination of high molecular arabinoxylan content in wort

摘要

In the past, successful attempts were made in cultivation and malting technologies to reduce the content of β-glucans in brewing barley and malt and thus prevent technological problems in the brewing process caused by these substances. Ara-binoxylans occur mainly together with P-glucans in the grain and show very similar properties. Nonetheless they have not been included in most of these studies. An analytical method for the determination of high molecular arabinoxylan was established at the Research Institute for Raw Materials in order to monitor their content in wort and beer.
