Relatively little is known about the genetic control of agronomic traits in common wheat (Triticum aestivum L.) compared with that follow Mendelian segregation patterns. A doubled-haploid population was generated from cross RL4452x'AC Domain' to study inheritance traits: plant height, time maturity, lodging, grain yield, test weight, and 1000-grain weight. This includes genetics 2 western Canadian marketing classes. Composite interval mapping conducted a microsatellite linkage map,...
The physiological cholesterol-lowering benefits of β-glucan have been well documented, however, whether modulation gut microbiota by is associated with these effects remains unknown. objectives this study were therefore to determine the impact on composition in mildly hypercholesterolemic individuals and identify if altered are bioactivity improving risk factors cardiovascular disease (CVD). Using a randomized, controlled crossover design, received for 5-week either treatment breakfast...
Abstract A method for the determination of total dietary fiber (TDF), as defined by CODEX Alimentarius, was validated in foods. Based upon principles AOAC Official MethodsSM 985.29, 991.43, 2001.03, and 2002.02, quantitates high- low-molecular-weight (HMWDF LMWDF, respectively). In 2007, McCleary described a extended enzymatic digestion at 37C to simulate human intestinal followed gravimetric isolation quantitation HMWDF use LC quantitate soluble (LMWSDF). The thus complete range components...
Abstract Wheat grain quality is a complex group of traits tremendous importance to wheat producers, end‐users and breeders. Quantitative trait locus (QTL) analysis studied the genetics milling, mixograph, farinograph, baking, starch noodle colour in spring population RL4452/‘AC Domain’. Forty‐seven were measured on 99 QTLs detected over 18 chromosomes for 41 traits. Forty‐four these mapped three major QTL clusters 1B, 4D, 7D. Fourteen near Glu‐B1 , 20 plant height chromosome 10 time maturity...
Abstract Underlying mechanisms responsible for the cholesterol-lowering effect of β -glucan have been proposed, yet not fully demonstrated. The primary aim this study was to determine whether consumption barley lowers cholesterol by affecting absorption, synthesis or bile acid synthesis. In addition, aimed assess underlying are related 7 α hydroxylase ( CYP7A1 ) SNP rs3808607 as proposed us earlier. a controlled, randomised, cross-over study, participants with mild hypercholesterolaemia n...
Abstract A method for measurement of total dietary fiber (TDF) has been validated. This is applicable to plant materials, foods, and food ingredients as consumed, consistent with the 2009 CODEX definition (ALINORM 09/32/REP), measures insoluble (IDF) soluble (SDF), comprising SDF that precipitates in presence 78% ethanol (SDFP) remains (SDFS). The an update AOAC Method 2009.01 addresses each issues identified by analysts using over past 8 years. 13 laboratories participated study, all...
The specific objective of the human feeding trial was to elucidate role bile acids and short chain fatty in mediating cholesterol lowering effects barley β-glucan.
Strongfield durum wheat (Triticum turgidum L. var durum) is adapted to the production area of southern Canadian prairies. It combines high yield, grain protein concentration, and low cadmium concentration. has shorter, stronger straw than Kyle, similar maturity disease resistance other currently registered cultivars. Key words: Triticum durum, wheat, cultivar description, protein,
The aim of the present study was to determine if consumption barley tortillas varying in fibre and/or starch composition affected postprandial glucose, insulin, glucagon-like peptide-1 (GLP-1) or peptide YY concentrations. A double-blind, randomised, controlled trial performed with twelve healthy adults. They each consumed one five a glucose drink on six individual visits separated by at least 1 week. Tortillas were made from 100 % flour blends using different milling fractions achieve...
ABSTRACT Data on the quality of durum wheat genotypes grown under eight environments (site‐year combinations) were evaluated to determine relative effects genotype and environment characteristics associated with gluten strength, protein content, pasta texture. The 10 assessed in this study represented a range strength types from very strong U.S. desert genotype, Durex, medium Canadian Plenty. Considerable genetic variability was detected for all studied. Genotype‐environment interaction...
Abstract Durum breeders use a range of techniques in the development new cultivars. An important selection criterion is rheological properties semolina dough and durum wheat this cultivars using techniques. Because need to process large numbers genotypes encountered breeding programs, methods that are inexpensive, rapid, require small amounts sample correlate with quality desirable. Using material, study investigated relationship between glutenin subunit composition two traditional tests...
The occurrence of fusarium head blight (FHB) in oat Canada is reviewed, and preliminary results recent studies Manitoba are presented. Fusarium was common crops surveyed southern 2002 2003, but visually, only low levels were evident. graminearum F. poae the principal fungal species recovered from affected kernels. Levels spp. deoxynivalenol (DON) varied among cultivars tested for their reactions to FHB field trials. Putative Fusarium-damaged kernels also assessed, identification equivocal....
Alkylresorcinols (ARs) are phenolic lipids that present in high amounts the bran layer of different cereals. Rye samples, cultivar Hazlet, and a white rye genotype, RT202, were analyzed for their antioxidant properties AR content composition, based on six fractions bran, where 1 was outermost fraction 6 closest to endosperm. Gas chromatography-mass spectrometry (GC-MS) analysis demonstrated most commonly found homologue Hazlet is C19:0 total amount ARs decreases from innermost fractions. The...
Phenolic acids are thought to be involved in modulating the activity of intestinal α-glucosidase which is desirable treatment and management diabetes. However, limited data exist on structural relationship between phenolic acid derivatives inhibition. Thus five (5) hydroxycinnamic six (6) hydroxybenzoic four (4) conjugates common cereal grains were used investigate kinetics enzyme α-Glucosidase was inhibited by 4%–55% presence derivatives. The inhibition potency dependent number hydroxyl...
Purpose This paper aims to investigate the repeatability of Stereolithography (SLA) process and provide reliable guidelines minimize energy consumption without sacrificing part quality. To tackle these aims, an extensive experimental campaign has been conceived: two different machines (of same model) have operated in production environment, specimens parts with orientations manufactured. Design/methodology/approach A two-step carried out. In first stage, surgical guides were printed...
ABSTRACT Field studies were conducted over three years at two locations in Saskatchewan, Canada, to determine the effect of nitrogen fertilizer on protein quantity and strength 10 cultivars durum wheat ( Triticum turgidum L. var. ) representing a range gluten strength. Increasing resulted increased content all across environments. Cultivars clearly differentiated basis using index (GI), SDS sedimentation (SDSS), alveograph indices overpressure P deformation energy W ), mixograph peak (ETP),...
ABSTRACT Five Canadian oat genotypes were grown at six environments in Manitoba to assess the effects of genotype, environment, and genotype‐by‐environment interaction on starch properties end‐product quality. Genotypic variation was significant for total starch, amylose content, swelling volume (SSV), Rapid Visco Analyser (RVA) pasting viscosities, differential scanning calorimetry (DSC) thermal properties, gel texture as well quality flakes cooked oatmeal made by laboratory‐scale...
ABSTRACT The physiochemical characteristics of β‐glucan in oat and barley foods can affect human physiological response. A method for continuous measurement viscosity with a Rapid Visco Analyzer (RVA) was developed to overcome the complexity common protocols based on vitro digestion methods. effects several parameters solubility were considered. Oat cereal showed different RVA profiles depending their characteristics. Products high starch exhibited initial that reduced by α‐amylase action,...
