Use of Bacillus subtilis starter cultures during red sorghum malting
… used to inhibit mould growth during red sorghum malting. Improved conditions for achieving good malt properties were studied and mathematical models are proposed for the induction and the repression phases of α- and β-amylase synthesis. The problems associated with the hydrolysis of β-glucans and …

The enzymomology of the malting, milling, mashing and fermentation processes within the scotch malt whisky industry
… as within a single variety. These may be due to malting conditions or to geographical, environmental and/or climatic factors associated with barley cultivation. The activities and fate of the enzymes were followed during the production process. Although the distillery where the study was carried …

Effects of malting and dehulling on the functional structural antioxidant properties of Bambara Groundnut (Vigna Subterranean) flour
… aimed to examine the influence of dehulling and malting (120 h) on the functional, structural, and antioxidant properties of flours from three Bambara groundnut (BGN) varieties (cream, brown, and red). The techno-functional, thermal, pasting, structural properties, nutritional quality, …

Lactic acid bacteria fermentation of wort as a tool to add functionality in malting, brewing and novel beverages
This thesis addresses the investigation of several strains of LAB for biopreservation using in vitro and in situ studies, as well as for acidification of wort to be applied during sour brewing and as novel beverages. The impact of bacterial carboxylic acids, with emphasis on phenolic antifungal …

Effects of soaking and malting on thermal, functional and antinutritional properties of finger millet (Eluesine coracana L. Gaertn) flour
… This research explored how soaking and malting impact the colour, pasting behaviour, thermal properties, crystallinity, and functional characteristics of both light and dark brown finger millet, along with sorghum (Sorghum bicolor) (included as reference). A central composite rotation …

Assessing wild barley germplasm in multiparent and advanced backcross populations for mapping, gene discovery, and improvement of malting barley
… 25 wild barley accessions to the 6-rowed malting barley cultivar Rasmusson. The 25 wild barley parents were selected to capture approximately ~90% of the allelic content of the wild barley diversity collection (WBDC), which contains 318 accessions sourced from across wild barley’s native …

Physicochemical, antioxidant and microstructural properties of malted finger millet (Eleusine coracana) flour(s) and their use in gluten-free biscuits.
… millet is a gluten-free crop with outstanding malting qualities, and a low glycaemic index. The study aimed to determine the physicochemical, antioxidant, and microstructural properties of malted finger millet flours (light and dark brown) and their use in gluten-free biscuits. The two …

Development of a toolbox for the reduction of hordeins in barley malt beers
… content of beer It is well known, that during malting and brewing hordeins are reduced, but they still remain in beer at levels above 10 mg/kg. During malting, hordeins are broken down to form new proteins in the growing plant. Model malting and brewing systems were developed and used to test, …

The Genetic Architecture of Grain Quality and its Temporal Relationship with Growth and Development in Winter Malting Barley (Hordeum vulgare)
This thesis explores the genetic architecture of malting quality within the Virginia Tech barley breeding program, and discusses implications for imposing selection on complex traits that are difficult to phenotype. Malting quality measures are destructive, and can not be performed before selection …

Avoiding trade-off when enhancing Fusarium head blight resistance of barley
… and heading date QTL on 3H. QTL analysis of malting traits of Chevallier, an English malting landrace, was also undertaken. Chevallier compared favourably to NFC Tipple, a modern malting cultivar, for several malting characteristics including free amino nitrogen, diastatic power and wort …

Optimation of Ontaku/ Oshikundu: Pearl millet and sorghum malts quality and conveniet premix development
… of this brew are the absence of standardised malting process that gives a consistent malt quality and microbial safety. The lack of standard ingredient ratios (flour/meal: malt: water) of brewing. Also, the sedimentation of adjunct particles at the bottom (dreg), thus creating the difference …

Virginia-grown Barley for Craft Brewing: Evaluation of Free Amino Nitrogen Content and Malt Sensory Characteristics
Regionally-Grown barley is in demand for craft malting and brewing in Virginia. Barley lines suited to both Virginia's climate and craft brewing applications are currently under development. Free amino nitrogen (FAN) is a malt quality parameter that influences beer flavor directly and via yeast …

Investigation of winter wheat sowing date management and genetic architecture of malting quality in winter barley and milling/baking performance in soft red winter wheat
… for 11 phenotypic traits associated with malting quality. QTL mapping validated six previously reported regions (Mohammadi, et al., 2015, GrainGenes 3.0, 2019) that are strongly associated (LOD > 3.0) with relevant malt quality traits. Phenotypic variation for malt quality was largely and …

From field-to-glass: optimising field beans (<i>Vicia faba </i>L.) and peas (<i>Pisum sativum</i> L.) for brewing and distilling
… demonstrated the potential of growing malting quality barley in the presence of legumes without the application of N fertiliser. Opportunities for breeding specifically for IC conditions, for example increased cereal tillering and N availability complementarity, combined with a refresh …

Technological Innovations for Mid-Atlantic Cropping Systems
… the plant growth regulator trinexapac-ethyl to malting barley in Virginia. Plant growth regulators can help plants remain upright during strong winds, thereby preserving grain quality and yield. However, this study demonstrated that risks of plant injury also exist. Application should be …

Developing Low-GN and GN-zero Winter Malt Barley for the Eastern United States
… a multi-pronged effort to develop GN-zero winter malting barley adapted to the Eastern U.S. In 2023, grain from 220 elite malt breeding lines and two known GN-zero checks were grown in Blacksburg, VA and screened for GN content using a colorimetric assay. All VT lines tested positive for presence, …

BIOCHAR AMENDMENT TO IMPROVE SOIL PRODUCTIVITY WITH PARTICULAR EMPHASIS ON THE INFLUENCE OF SOIL TYPE
… keeping it within the tolerable limits of the malting barley industry in both cases. Potentially toxic elements (PTEs) within the barley grain (Zn, Cu, As, Ni, Cd and Cr) were not raised to levels critical to food safety. The overarching conclusion is that soil type, as defined by its physical, …
