J. Inst. Brew. 114(1), 27–33, 2008 Ten different barley cultivars and their corresponding malts were used to obtain different fractions. Phenolics extracted belonged to free, soluble esters and(More)
The pattern of the monomeric and oligomeric flavan-3-ols for 10 barley varieties and the corresponding malts were identified and quantified using high-performance liquid chromatography-ultraviolet(More)
An analytical methodology based on the sample extraction with methanol/formic acid by ultra-sonication and subsequent analysis by high-performance liquid chromatography with diode array detection is(More)
AbstractThis paper reports a novel application of microwave-assisted extraction (MAE) of polyphenols from brewer’s spent grains (BSG). A 24 orthogonal composite design was used to obtain the optimal(More)
Abstract The antioxidant activity and phenolic composition of brewer's spent grain (BSG) extracts obtained by microwave-assisted extraction from two malt types (light and dark malts) were(More)
The α-diketones glyoxal, methylglyoxal, and diacetyl were determined in selected beer and wine using a procedure involving the use of C18 solid phase extraction columns to remove interferences and(More)
The aim of the present work was the development of a suitable methodology for the separation and determination of phenolic compounds in the hop plant. The developed methodology was based on the(More)
