Z. Deng,J. Tian,Y. Zhang,C. Sun
Agricultural Journal , 2013,
Abstract: Three winter wheat cultivars from eight different locations with 3 replications were used to study the effects of genotypes, environments and their interactions on high molecular weight of glutenin subunits (HMW-GS) expression and its relationship with steamed bread and baking quality. The results indicated that although some subunits were affected by environments, genotypes played an important role for X-type HMW-GS, Y-type HMW-GS, Glu-D1location and Glu-B1 location. Total HMW-GS amounts were affected by the interactions between genotype and environment. Individual HMW-GS content of the same genotype was affected by environment in different degree. Yantai location was superior to others locations for many HMW-GS expression amounts. The same kind of HMW-GS from different genotypes appeared different in the same environments. Correlation analysis appeared HMW-GS expression amount positively correlated with bread volume, and negatively with bread peak firmness. Effects of individual and total HMW-GS on steamed bun quality were different from that on bread quality. And effects of total HMW-GS on bread volume were better than that of individual HMW-GS. Bread quality was determined firstly by HMW-GS types, secondly by the HMW-GS expression amount; while steamed bread quality was mainly affected by HMW-GS expression amounts.

Abstract: In this study, quantitative trait loci (QTLs) with additive effects, epistatic effects for CNSB specific volume in bread wheat (Triticum aestivum L.), were studied in cultivars Huapei 3 and Yumai 57 (Triticum aestivum L.). The DH population and the parents were planted in 2007 and 2008 in Tai’An and 2008 in Suzhou. QTL analyses were performed using the software of IciMapping v2.2 based on the mixed linear model. Five putative QTLs for CNSB specific volume were detected on 5 chromosomes where single QTLs explained 5.11% to 9.75% of phenotypic variations. All of them had negative effects on specific volume and were contributed by Yumai 57 alleles. Qsv-1B was detected in both environment 1 and 3 with 13.88% and 4.83% phenotypic variations which had positive effects and was transmitted by Huapei 3 alleles. Fourteen pairs of QTLs with epistatic effects were detected for specific volume. Seven major QTLs, Qsv-1B/Qsv-3A, Qsv-2D/Qsv-3A, Qsv-3A/Qsv- 5B1, Qsv-1B/Qsv-6D, Qsv-2D/Qsv-4D, Qsv-4A/ Qsv-6B and Qsv-3A/Qsv-7D could account for 13.88%、20.39%、18.88%、12.31%、18.78%、11.98%, and 17.05% of the phenotypic variation of specific volume. The information obtained in this study will be useful for manipulating the QTLs for CNSB specific volume property by molecular marker-assisted selection (MAS).

Abstract: Population varieties can meet the needs of organic farming as they are composed of diverse genotypes and have nutritional and sensory characteristics of interest. Their intra-specific genetic variability helps to adapt to the diversity of soil and climate conditions, management practices and needs. Moreover, an integrated organic bread sector has emerged willing to use more wheat populations. To explore sensory and nutritional potential of bread wheat populations, hedonic tests, sensory profile and nutritional analyses were implemented on eight wheat population varieties and one modern variety. Hedonic tests revealed consensus among consumer when ranking according to specific sensory characteristics and showed preferences for red wheat breads. Descriptive sensory test showed significant differences between genotypes on 6 out of 11 descriptors and confirmed the sensory specificity of red wheat accessions. Nutritional analyses showed differences especially on minerals content. Sensory differences between breads from different genotypes can be perceived both by trained and untrained panels as suggested by results. Moreover, red accessions showed specific sensory characteristics which are well-perceived by the two panels. Breeding effort should be maintained for high diverse genotypes with improved sensory and nutritional qualities adapted to organic farming conditions. Indicators like kernel colour should be sought to help integrate such criteria.

Auricularia polytricha is a functional food material that contains numerous bioactive health-promoting compounds. This study demonstrates the novel application of A. polytricha powder (APP) in steamed bread production. Moreover, this work aimed to determine the influence of the direct addition of APP on the sensory, textural, physical, and in vitro antioxidant properties of steamed breads. Steamed breads enriched with 5% APP had higher consumer acceptability than those enriched with 2.5%, 5%, 7.5% and 10% APP. In addition, supplementation with APP significantly enhanced the antioxidant activity of steamed breads during digestion in vitro. Our study suggests that A. polytricha is a valuable source of active compounds for steamed wheat breads.

Abstract: Lots of investigation has been done in order to increase wheat yield per acre in Iran, but there is not enough study about quality of produced wheat. Bread quality in Iran has been deteriorated in recent years, mostly due to employing wheat flours of low quality. Thus the present study was conducted to find the chemical and rheological properties of four bread wheat cultivars (Omid, Rosshan, Golestani and “Kal”) produced in Sabzavar region. The results indicated that the quantity and quality of “Kal” wheat gluten are more desirable in comparison to the other varieties. The rheological experiment results indicated that the Omid wheat flour is the best regarding the dough resistance coefficient and alfa amylase activity. The alfa amylase activity of all flours was low. Appropriate time for fermentation of bread dough for all flours was 75 to 90 minutes. Mixture of one to ten ratio of Roshan and Omid flour produced bread with better quality. The results also indicated that the rheological properties of “Kal” flour dough such as mixing resistance, breaking point resistance and valorimeter value are acceptable. The bakery properties of “Kal” flour is better than Rosham flour. The “Kal” variety of wheat is the same as Roshan variety and the only difference between them is the region of production and farming conditions. It shows that farming condition is one of the important factors affecting bread wheat quality.

In this work the effect of six varieties of durum wheat semolina on the bread physico-chemical and sensorial properties was addressed. In particular, whole grains of durum wheat (Anco Marzio, Claudio, Core, Iride, Saragolla and Cappelli) were finely milled by using an ancient stone milling system. Texture analysis was carried out on both dough and bread samples to evaluate their firmness. Furthermore, tomographic analysis was performed on the bread samples in order to provide a more detailed view of their texture. The Glucose Equivalent, the chemical and the sensory analyses of the bread were also determined. Results highlighted that the lowest Glucose Equivalent valuewas achieved in bread produced with the Anco Marzio cultivar, which appeared instead the worst in terms of texture. Among the investigated samples, bread from the Cappelli variety showed good structural characteristic, a moderate Glucose Equivalent compared to the reference sample (CTRL) and the highest sensory quality.
