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.

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.

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
