In barley endosperm arabinoxylan (AX) is the second most abundant cell wall polysaccharide and in wheat it is the most abundant polysaccharide in the starchy endosperm walls of the grain. AX is one of the main contributors to grain dietary fibre content providing several health benefits including cholesterol and glucose lowering effects, and antioxidant activities. Due to its complex structural...

Abstract The paper presents studies of the enzymatic activity barley grains different varieties. In experiments with varieties malting barley, isoforms amylolytic enzymes was determined at pH = 5.5, 7.0, 8.0 using a phosphate buffer system (1/15 M buffer). in germinated grain after removal sprouts and roots. to determine amylases study action acidic (pH 5.5), neutral 7) alkaline 8) environments...

Cultivation of malting barley is particularly challenging as the requirements growers, for high yield, and that brewing industry, seeking a specific quality criteria, must be met simultaneously. Furthermore, significant genotypic environmental variations in grain yield properties may occur. To investigate relationships between parameters spring barley, 2-year experiment was carried out order to...

Malting is usually carried out on intact barley seed, while hull is still attached to it. In this study, oat grain with and without hull was subjected to controlled germination to optimize its enzymes activity, in such a way that lipase has the lowest and αamylase and proteinase the highest activities. Since pH has a great impact on the activity of the enzymes, the pH of germination media was s...

The routine and prophylactic use of fungicides in cereals leads to increased aggressiveness Fusarium infections. Cross-resistance triazole compounds represents a significant health risk both plants humans. application some widely used causes production DON. Residual concentrations hydrophobic triazoles change chemical profile malt cause delayed fermentation with an impact on alcohol content. In...

Polyacrylamide gel electrophoresis (PAGE) at acidic pH and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of barley seed storage proteins, hordeins, have been widely applied for barley variety discrimination (Cooke, 1995; Wrigley, 1995; White and Cooke, 1992). However, their use is limited to variety grouping, while full differentiation could not be achieved (Lamelland and...

There is an increasing market for locally grown malting barley (Hordeum vulgare L.) in the Northeast US. Malting must meet certain quality standards acceptability brewing market. Up-to-date recommendations are needed regionally adaptation to ongoing climate change. A two-year field experiment was conducted assess interactive influence of three dates planting (5 September, 15 and 25 September), ...

Drought is a major abiotic stress impeding the yield of cereal crops globally. Particularly in Mediterranean environments, water becomes a limiting factor during the reproductive developmental stage, causing yield losses. The wild progenitor of cultivated barley Hordeum vulgare ssp spontaneum (Hsp) is a potentially useful source of drought tolerance alleles. Wild barley introgression lines like...

T-2 and HT-2 toxins are two of the most toxic members of type-A trichothecenes, produced by a number of Fusarium species. The occurrence of these mycotoxins was studied in barley samples during a survey carried out in the 2011-2014 growing seasons in climatically different regions in Italy. The percentage of samples found positive ranges from 22% to 53%, with values included between 26 and 787 ...
