The influence of the mass fraction of flax in the composite mixture on the state of the carbohydrate – amylase complex of the studied system was studied. It was found out that the maximum viscosity of the suspension and the rate of starch gelation in a mixture of wheat flour with whole-ground flax is lower than in the suspension, where the dispersed phase was wheat flour, but higher than that, where the dispersed phase is flax. The influence of flax on the rheological characteristics of wheat dough in the Chopin+ Mixolaba protocol was revealed.  It is found out that with an increase in the mass fraction of flax in the composite mixture from 5 to 20%, the formation time of the test and its water absorption capacity increases, and the stability decreases. When the mass fraction of flax increases, the torque values at the extreme point of the function C2, which characterizes the dilution of the dough, increase; and at the point C5, which characterizes the retrogradation of starch, they decrease.

Vital gluten is often used in baking to supplement weak wheat flours and improve their baking quality. Even with the same recipe, variable final bread volumes are common, because the functionality differs between vital gluten samples also from the same manufacturer. To understand why, the protein composition of ten vital gluten samples was investigated as well as their performance in a microbaking test depending on the water content in the dough. The gluten content and composition as well the content of free thiols and disulfide bonds of the samples were similar and not related to the specific bread volumes obtained using two dough systems, one based on a baking mixture and one based on a weak wheat flour. Variations of water addition showed that an optimal specific volume of 1.74–2.38 mL/g (baking mixture) and 4.25–5.49 mL/g (weak wheat flour) was reached for each vital gluten sample depending on its specific water absorption capacity.

The effects of amaranth and quinoa flours and protein isolates prepared from amaranth and quinoa seeds on the rheological properties of wheat flour dough and bread were studied using new recording instruments, the micro Z-arm mixer (for dough) and the SMS-Texture analyser (for bread crumb). The addition of 10% amaranth or quinoa flours did not cause significant changes in rheological properties. However, higher additions (20% and 30%) resulted in significant changes in stability, the degree of softening and elasticity. Substitution of wheat flour by amaranth or quinoa flours resulted in an increase of water absorption capacity. A significant reduction of specific volume and an increase of resistance to deformation (firmness) of the crumb of breads prepared from flour mixtures containing high percentages of amaranth or quinoa flours was observed. The addition of protein isolates did not significantly influence the main rheological parameters of dough, and bread crumb.

Abstract This study evaluated the effect of addition of Brachystegia eurycoma flour (BEF), a natural source of hydrocolloids, on the physicochemical properties of whole millet flour (WMF) and the sensory attributes of its gluten-free bread. BEF and sodium carboxylmethyl cellulose (a reference hydrocolloid) were added to WMF at 1.5 and 3% proportions, and breads were baked from the blends. Wheat flour (100%CWF) bread served as the control. Amylose level decreased significantly (p < 0.05), while water absorption capacity, peak and final viscosities of the blends increased with increasing proportion of BEF. The 100%CWF bread had better sensory qualities than WMF-BEF breads. Hence, BEF improved the physicochemical properties of WMF-BEF blend, but did not alter the sensory qualities of its gluten-free bread.

Amaranth Flour

The technological properties of full-fat amaranth flour depend on the varietal characteristics of the Ukrainian amaranth grain and differ significantly from amaranth flour from flakes and amaranth flour from groats. In comparison with patent wheat flour, amaranth flour has a lower moisture content, higher water absorption capacity and  autolytic  activity. The variety of Amaranthus hypochondriacus significantly effects on the whiteness of full-fat flours, the lightest of which is obtained from the grain cultivar Kharkivsky-1. A higher fat, protein, and fibre content makes amaranth flours more acidic. The water absorption capacity of the flours shows positive correlation with their autolytic activity (+0.885). The acidity negatively correlates with the moisture (-0.939) and whiteness  (-0.814)  of the flours. Using amaranth flour of the different types to replace 5, 15, and 25% of patent wheat flour when making bread increases its specific volume and crumb porosity and decreases its shape stability. The positive correlation of the overall quality of the bread samples under study with their specific volume (+0.540) and the negative correlation with the acidity (- 0.685) are statistically significant. The shape stability negatively correlates with the porosity (-0.598), and the latter positively correlates with the specific volume (+0.533). The use of full-fat amaranth flour increases the specific      volume       and      porosity      of      bread      by      1.1–1.3    and 1.1 times respectively. The use of defatted flour from flakes leads to a 1.3–1.9 -fold increase in the specific volume and to a 1.1–1.2 -old increase  in the porosity. Incorporation of amaranth flour from groats allows increasing the specific volume and porosity of bread by 1.3–1.5 and 1.1–1.2 times respectively. The bread samples with 25% of all amaranth flours considered and with 15% of full-fat flour of the Liera variety  have  the lowest consumer characteristics. It has been proved that using 5–15% of full-fat flour from the amaranth grain of variety Kharkivsky-1 and defatted flour from flakes and groats (by-products of processing amaranth grain into oil) improves the quality and nutritional value of bread.

Composite Bread

The present study was undertaken to develop bread from composite flours. Composite flours were prepared by blending wheat flour with watermelon rind flour in ratios of 100:0 (AB1), 90:10 (AB2), 80:20 (AB3), 70:30 (AB4) and 60:40 (AB5), respectively. This study was carried out to ascertain the effects of watermelon rind flour at different replacement levels (0%, 10%, 20%, 30%, 40%) on the proximate and functional properties of composite wheat bread. The results of proximate properties determination on wheat/flour blend gave low bulk densities of 0.54g/cm3 to 0.60g/cm3, high water absorption capacity of 2.389 to 3.044 g/g as well as a high swelling capacity of 5.764 to 7.610 g/g and a low oil absorption capacity of 1.608 to 2.150 g/g. The results of proximate composition of composite bread revealed an increase in % protein, % carbohydrate and % ash from 15.7% to 18.8%, 47.1% to 52.0% and 0.6% to 1.2% respectively and a subsequent decrease in % fat from 18.4% to 13.8. There was a reduction in energy density for composite bread. The functional properties of composite flours such as swelling capacity, water absorption capacity, oil absorption capacity and bulk density were increased with increase in the incorporation of watermelon rind flour with wheat flour. Thus, the results indicate that by incorporating watermelon rind flour, it is possible to enhance the nutritional quality, chemical and functional properties of bread.

The article discusses the analysis of studies on the effect of activated water on the preparation of wheat grains grown in an arid climate for high-quality flour grinding. The aim of the study was to study the effect of the use of activated water on the rheological properties of type IV wheat flour grown in arid climates, in the preparation of wheat flour for grinding. In a study of the strength of the gluten framework and the rheological properties of the dough increased by increasing the water absorption capacity of flour when using activated water at 80 and 100 Hz when preparing local wheat grains with low baking properties in a dry climate for grinding flour

<p><em>Functional properties of sausage rolls made from cocoyam and wheat flour enriched with soybean flour was studied. Cocoyam cormels and soybean were processed into flour, which were later used to formulate composite flour blends, with wheat flour in the ratio of: 90:10:0 (control 1), 80:10:10, 70:10:20, 60:10:40, 50:10:30, respectively, while 0:10:90 served as control 2. The result of the functional properties showed variation in behavior. There were no significant difference (p?0.05) in pH, bulk density, swelling index, foam capacity and emulsion capacity of the flour samples while significant difference (p?0.05) existed in water absorption capacity, oil absorption capacity and wettability.</em></p>
