Wheat Flours

Three wheat cultivars, Elnelain, Nepta and Argeen were studied for their various quality and rheological characteristics compared with the Australian wheat flour (control). Physicochemical characteristics as well as farinograph, extensograph, gluten content, sedimentation value and bread quality were assessed. Significant differences (P ≤ 0.05) were found for hectoliter weight and 1000 kernel weight between the Australian and Sudanese wheat cultivars. However, Sudanese wheat flours had a lower wet gluten (22.7-28.9 g), sedimentation values (15-20 ml), water absorption(57.9-66.4%), dough development time(2.5-6.8 min), stability(1.5-7.9 min), resistance to extension(160-304 Bu), energy (62-80 cm2) and bread specific volume (3.06-3.40 cm3) compared to the Australian one. Nepta cultivars gave the best characteristics of farinograph, extensograph and the highest bread specific volume among Sudanese wheat investigated.

Wheat Flours

The physicochemical and antioxidant properties of dough and bread were measured in wheat flours substituted with two types of bran (HMB: bran pulverized by a hammer mill and JMB: bran pulverized by a jet mill) at various ratios (0%, 5%, 10%, 15%, 20%, and 25%) of substitution. The particle size of hammer mill bran (HMB) (119.71 µm) was larger than that of jet mill bran (JMB) (25.78 µm). Wheat flours substituted with HMB contained more total dietary fiber than those with JMB. A significant increase of water absorption and dough development time in Mixolab® analysis was observed depending on the level of HMB or JMB substitution. The breads made with HMB or JMB (5% or 10%) showed a higher specific volume and lower crumb hardness than the control bread. However, breads made with ≥15% HMB or JMB had a decreased specific volume and increased crumb hardness. Overall, breads made with wheat flour substituted with 5%–10% HMB or JMB were of a higher bread quality and had more antioxidant properties.

Spray Dried

The effect of incorporating different levels of spray-dried sourdough (3, 6, 9, and 15% w/w) on flour characteristics and dough properties of two wheat flours was studied. As the spray-dried sourdough level in the blends increased, the pH values significantly (P < 0.05) decreased. Wet gluten content and sedimentation values were decreased in the flours containing spray-dried sourdough compared to those of the control. Water absorption significantly increased compared to that of the control. However, the dough development time was not affected by sourdough powder addition. Degree of softening significantly increased with an increase in the sourdough level and dough stability was significantly reduced. Doughs incorporating sourdough powder showed higher resistance to extension and lower dough extensibility than the control doughs.

Simple correlations between a number of quality parameters, their heritabilities and an evaluation of the best combination of these parameters to predict loaf volume, were determined from data for 26 cultivars of spring wheat grown at four locations in Western Canada. Highly significant correlations between remix loaf volume and each of Zeleny sedimentation value, farinograph dough development time, farinograph mixing tolerance index, proportion of residue protein, and glutenin protein were obtained. Sedimentation value, 1000 kernel weight, mixing tolerance index, flour yield, farinograph absorption, and remix loaf volume all had high heritabilities over the four locations. Using the simple correlations as a guide, regression formulae yielding the best predictions of remix loaf volume were developed. Residue protein content, Zeleny sedimentation value, and farinograph dough development time provided the most useful information for predicting baking quality by a single test.

<p>The present study aimed to evaluate the effect of the wheat varieties newly introduced in Rwanda on the physicochemical characteristics of their whole wheat grains in order to know their potentials for processing. Gihundo wheat grain variety had the highest values for extraction yield (99.20 %), contents of ash (1.47 %) and total dietary fiber (15.97 %), water absorption capacity (89.00 %), dough development time (7.62 min) and brightness (84.67 %). For the same physicochemical characteristics, whole flour from Nyaruka wheat variety showed the lowest values for extraction yield (96.20%), water absorption capacity (80.00 %), dough development time (6.33 min) and brightness (80.33), while whole flour from Reberaho wheat variety exhibited the lowest values for the contents of ash (0.98 %) and total dietary fiber (12.44 %). The protein content ranged between 10.00 % and 10.85 % for whole flours from all wheat varieties. The results showed that whole flour from Gihundo wheat grain variety exhibited high values for most of the physicochemical characteristics determined in comparison to the other three varieties. It is important to select grains or flour from these wheat varieties newly introduced in Rwanda based on the individual cultivar because their derivative products could have a more desired quality.</p>

Milling Yield

Milling yield, maximum dough resistance (Rmax), dough extensibility, flour protein concentration (flour protein), particle size index (PSI), water absorption, and dough development time are important determinants of grain quality and are routinely evaluated in Australian wheat breeding programs. Information on allelic variation at the 6 loci determining glutenin proteins is also regularly obtained and used to predict Rmax and extensibility. For each character, except dough development time, 4029 observations on 2377 lines and 94 environments were analysed to estimate genotypic and environmental variances, heritabilities, genotypic and environmental correlations, and the effects of glutenin genes. A subset was analysed for dough development time. Milling yield, Rmax, extensibility, PSI, water absorption, and dough development time had intra-class correlation coefficients, or broad-sense heritabilities, between 0.66 and 0.76, and extensibility had a value of 0.52, with flour protein at 0.36. Genotypic and environmental correlations between extensibility and flour protein were high at +0.78 and +0.85, respectively. Rmax had a genotypic correlation with dough development time of +0.67, which was substantially due to pleiotropic effects of glutenin genes. Rmax, extensibility, PSI, and dough development time were influenced by glutenin genes. For Rmax about 50% of the genotypic variance could be explained by glutenin genes. For extensibility about 50% could be explained by flour protein, with 50% of the remainder by the inclusion of glutenin genes. For dough development time about 15% could be explained by flour protein, with a further 30% by glutenin genes. For PSI, about 40% of the genotypic variation could be accounted for by glutenin genes after the removal of the effects of flour protein and milling yield. We concluded that dough development time could be added to Rmax and extensibility as a trait that can be usefully predicted by the glutenin genes, but more work is required for PSI.

Overozonized wheat flour was added to unozonized wheat flour at three different ratios (M1: 1 : 1; M2: 1 : 2; and M3: 1 : 3), and the mixed flour was evaluated for quality properties, including pH, protein component, dough property, pasting property, and steamed bread quality. The pH of the mixed flour gradually increased as the addition content of overozonized flour decreased. The three mixed flour had higher insoluble polymeric protein (IPP) content than unozonized flour. Compared with overozonized flour, M1 and M2 flour did not show a significant difference in IPP content, but M3 flour exhibited a decreased IPP content. Three mixed flour had higher dough development time and dough stability time than both unozonized and overozonized flour, and there was no significant difference among three mixed flour in these two dough parameters. Peak, trough, and final viscosities of the three mixed flour were between those of unozonized and overozonized flour. Steamed bread of three mixed flour had larger specific volume and better texture than that of overozonized flour, with steamed bread of M3 flour showing the best attributes. Among the three mixed flour, M1 flour was the closest to overozonized flour in volatile compounds of steamed bread. These results suggested overozonized flour can be mixed with unozonized flour to decrease the deterioration of overozonization on the dough and food-making properties of wheat flour, but the mixing ratio should be taken into consideration to obtain a better quality.

Abstract The effect of replacing wheat flour with different kinds of wheat bran and spelt bran at level 5, 10 and 15 % on dough rheology, qualitative parameters of cookies as well as on sensory properties was studied. Addition of bran increased water absorption and mixing tolerance index, prolonged dough development time and decreased dough stability. It was also observed that incorporation of wheat bran modified qualitative parameters of cookies (volume, specific volume, spread ratio and porosity decreased). From the sensory evaluation resulted that higher amounts of wheat bran negatively affected taste, hardness and overall acceptability of cookies. Addition of bran up to 5 % resulted in cookies with high overall acceptability.
