In this paper volatile organic compounds (VOCs) from durum wheat cultivars and landraces were analyzed using PTR-TOF-MS. The aim was to characterize the VOC's profile of the wholemeal flour and of the kernel to find out if any VOCs were specific to varieties and sample matrices. The VOC data is accompanied by SDS-PAGE analyses of the storage proteins (gliadins and glutenins). Statistical analys...

A study was designed to sample and characterize 12 populations of wild emmer wheat in Jordan at the high-molecular-weight (HMW) glutenin and allozyme levels. Data were collected and individual plants were sampled from 207 permanent sampling points in three central, three peripheral, and six marginal populations during all or part of a five-year study period. Patterns of variation, based on four...

Spring durum wheat is an important raw material for producing diverse products such as couscous, bulgur, bread, and pasta. The quality of the dough significantly influenced by high-molecular-weight glutenins, allelic status which depends on region breeding program. In this study, a collection 69 cultivars promising lines were analyzed state Glu-A1 Glu-B1 using SDS-PAGE KASP PCR markers. Protein...

Gluten refers to a complex mixture of gliadins and glutenins. It can cause numerous foodborne disorders. In sensitive individuals gluten lead celiac disease (CD), wheat sensitivity allergy. Gliadin proteins are one the fractions. The aim this paper was examine how different conditions, mixing time (2.5, 5, 7.5, 10 min) sample with most commonly solvent 70% (v/v) ethanol isopropanol incubation (...

To support the introduction of local soft wheat varieties, Lebanese state has implemented, during recent years, an improvement program to select plant material with good productivity in semi-arid conditions that can lead national production can, at same time, meet quality needs expressed by processors. In present study, main biochemical components grains conventionally associated bread-making p...

Cereal Chem. 72(6):527-532 Wheat protein fractions, separated by the Osborne Solvent Fractionaseparated by HPCE. Combined results of this study and our previous tion Procedure, were characterized by high-performance capillary elecstudies provide a catalog of individual gliadin information from HPCE, trophoresis (HPCE). Each fraction was separated on a 27-cm fused-glass HPLC, acid-polyacrylamide...

Cereal Chem. 84(3):271-275 Wheat protein quantity and composition are important parameters for wheat baking quality. The objective of this study was to use fractionation techniques to separate the proteins of flour mill streams into various protein fractions, to examine the distribution of these protein fractions, and to establish a relationship between protein composition and breadmaking quali...
