This lecture is the 22nd to commemorate Horace Taberrer Brown, a truly remarkable polymath who made important contributions to brewing practice and science and to ‘pure’ science. The ideas that Brown and his collaborators developed in the 1890s r

We have confirmed that floatation in salt solutions can be used to separate less-dense, more mealy, lower nitrogen-containing barley from more dense barley with less good malting quality having more steely grains and higher nitrogen contents. This gi

In a previous study the patterns of release of bound β-amylase caused by various agents were investigated. In the present study the released β-amylase isoforms were purified and characterized. The agents used to release bound β-amylase at differen

The aim was to identify the mechanism(s) responsible for the release of bound β-amylase in soluble forms in vitro and during the germination of barley. Preparations of bound β-amylase, from barley, were treated with different agents including papai

Ferulic acid esterase activity was detected in extracts of barley malt using an assay employing a novel artificial substrate, mono-feruloyl glycerol. Mono-feruloyl glycerol has been synthesized and analysed to determine its degree of substitution and

β-Amylase was extracted from barley or malt using four physical techniques to break up grists which had been prepared using a Moulinex coffee grinder. Grinding with a Polytron homogeniser apparently completely disrupted all cells, as determined by t

The aim of this study was to clarify the roles of endogenous proteases and higher molecular weight thiols in the release of bound β-amylase, which occurs during barley germination. In resting barley grains (Hordeum vulgare L. cv. Torrent) five major

The aim of this study was to determine the role of low molecular weight thiols both in the release and activation of β-amylase during grain germination. In quiescent barley grains (Hordeum vulgare L. cv. Torrent) about 55% of the β-amylase was extr

Reduced and oxidised glutathione, cysteine, cystine and traces (too small to quantify) of γ-glutamyl-cysteine and cysteinylglycine were detected, in about the same amounts, in extracts of the embryos of dormant and mature barleys. During micromaltin
