The incorporation of germinated grains in food formulation is an increasing trend, due to its superior nutritional quality and health-promoting properties as compared to their ungerminated counterparts. The aims of this study were: (1) to improve the nutritional properties of sliced bread by the replacement of wheat flour (WF) with germinated quinoa (GQF), kiwicha (GKF), and cañihua (GCF) flours; and (2) to optimize composition of flour blends using a Simplex Centroid Mixture Design (SCMD), the desired function methodology and performing the screening of rheological parameters in bread doughs (development time, stability time, resistance to extension, gelatinization temperature, and maximum gelatinization). Bioactive compounds (total phenolic compounds, TPC; gamma-aminobutyric acid, GABA) and antioxidant activity (oxygen radical absorbance capacity, ORAC) of flours from germinated grains was performed. A total of 14 flour blends formulations based on GQF (5–15%), GCF (5–15%), and WF (80–90%) blends or GKF (5–15%), GCF (5–15%), and WF (80–90%) were included in the SCMD to determine the optimal dough that guarantees a sliced bread with technological and sensory quality. TPC, GABA, and ORAC in flours of germinated pseudocereals ranged from 72–134 mg gallic acid equivalents/100 g, 100–217 mg/100 g, and 448–3395 mg trolox equivalents/100 g, respectively. The results indicated that the substitution levels influence the rheological properties of WF doughs (control). Highest desirability values were observed for doughs produced from the following two flour blends: 87.6% (WF), 5% (GKF), and 7.4% (GCF); and 84.6% (WF), 5% (GQF) and 10.4% (GCF). This investigation clearly indicates that germinated pseudocereal grains could be used to produced sliced breads with higher nutritional quality and acceptable technofunctional properties.

Millet flour (water washed or alkali washed) was replaced with wheat flour (WF) at 0, 25, 50, 75, and 100% levels. Objectives of the research were to characterize the flour blends for their technical properties and to produce cookies with less or no gluten contents. All types of flour blends were evaluated for their pasting properties. The cookies were baked and evaluated for their textural and physical attributes. Inclusion of millet flour (both types) in wheat flour resulted in significant reduction in peak and final viscosities while setback viscosities were affected non-significantly. Pasting temperature was increased from 65 ℃ (100% wheat flour) to 91 ℃ (100% millet flour). The hardness of cookies was reduced in the presence of millet flour. Fracturability values of cookies with higher millet flour were higher as compared to control cookies (prepared from 100% wheat flour). Cookies prepared from blends having more that 50% millet flour were not much liked by sensory panelists. The phenolic contents of cookies containing higher levels of either water washed or alkali washed millet flour were found to be higher when compared to cookies prepared from plain WF (1.90 ± 0.14 mg gallic acid/g sample). The 2,2-diphenyl-1-picrylhydrazyl activity (%) of cookies ranged from 16.39 ± 0.34 (100% water washed millet flour) to 10.39 ± 0.26 (100% WF; control). The study will help the non-coeliac people to consume low gluten (≈1.6–6.5%) or gluten intolerant people to consume gluten-free cookies (0%) from millet flour having abundant of antioxidants and health-promoting polyphenols.

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.

The development of wheat-based foods that are enriched with proteins is increasingly popular. The purpose of this study was to compare the effects of partial replacement of wheat flour with whey and soy proteins (0–30%) on the rheological properties of dough and cookie-making quality. The incorporation of whey protein (WP) diluted the concentration of gluten, leading to an increase in dough development time (MDT) and breakdown torque and a decrease in stability time (MST) and minimum torque (MMT). The gelation of WP during the heat treatment increased dough peak torque (MPT), G′, and G′′. As a contrast, the addition of soy protein (SP) increased dough MST, MDT, and MMT. The aggregation of SP helped increase G′ and decrease tan δ of the dough in oscillatory shear tests. The weak gelling effects and higher water absorption of SP decreased MPT, G′, and G′′ of the dough during heat treatment. With SP, the spread ratio of cookies first decreased from 6.39 to 5.66 and then increased to 6.86, and the overall acceptability scores ranged from 6.62 to 7.02, indicating that the formed soy protein network helped maintain the dough structure for obtaining an improvement in the quality of bakery products.

Flour quality is influenced by the nature of the gluten and its various components. Gluten free flour made of pulses is known to enhance the nutritional quality of wheat flour. However, its addition can compromise the rheological and sensorial attributes of the bread. We used mixture design to optimize nutritional and technological qualities of a wheat–chickpea flour blend by adding milk powder as a natural organoleptic improver. A total of thirteen flour blends were prepared by incorporating 10 to 30% chickpea flour and 10 to 20% milk powder to wheat flour. Our results showed that the optimal flour blend consisted of 60% wheat, 24% chickpea, and 16% milk powder. Farinographic parameters of the optimal dough blend remained on par with those of the control dough (100% wheat flour), thereby preserving its bread-making quality. Sensory analysis of breads made from the optimal flour blend revealed no significant difference (p ≤ 0.05) from wheat flour for crumb and chewiness. Appreciation was brought to the appearance, crust, aroma, and taste in the optimized bread. This study suggests that chickpea flour can be suitably incorporated into bread wheat flour up to a percentage of 24% with 16% milk powder to produce bread with optimal nutritional quality while improving its sensory attributes and consumer acceptability.

The influence of the addition of partially defatted milk thistle seed flour was studied by analyzing the rheological properties of dough in order to further exploit the functionality of partially defatted milk thistle flour in bakery products. The rheological properties of dough were monitored using Mixolab 2 (Chopin Technologies, France). A rheofermentometer F4 (Chopin Technologies, France) was used to check the dough fermentation, and for the baking trials wheat flour, rye flour, and milk thistle flour were kept in the portion: 50:50:0 (control flour); 50:45:5; 50:40:10 and 50:35:15. The addition of different milk thistle flour in the mixtures resulted in a difference in the viscoelastic properties of the dough. The results showed a weakening of the gluten network in all trial mixtures evaluated. The dough development time values of the control flour were 1.20 min, while an addition of milk thistle flour in portions of 5, 10, and 15% increased these values to 1.30 min, 1.90 min, and 2,80 min, respectively. In addition to higher dough development time values, all trial mixtures exhibited also higher stability (5.07 min; 6.25 min and 8.03 min), when compared to the control flour (4.63 min). The trial mixture with 15% milk thistle flour had different characteristics of gelatinization and retrogradation. The rheofermentometer measured the dough characteristics during proofing, and the trial mixtures with the addition of MTF had a retention volume at approximately the same level as the control flour (WRF). The Volscan profiler was used to determine the bread volume and other parameters. All breads had high volume and specific volume values and can be rated as good, with good porosity and ratio. Mixtures containing 5%, 10% and 15% milk thistle flour added to wheat flour + rye flour maintained rheological parameters within the recommended limits for good technological behavior and, consequently, good quality of bakery products. From all of the above data, it can be stated that, with regard to their baking characteristics, these flour mixtures fall into the category of flours suitable for bakery products.

Hulless barley (Hordeum vulgare L.), also known as highland barley, contains nutritional compounds, such as β-glucan and polyphenol, which can be added to wheat flour to improve the dough nutritional quality. In this study, different formulated dough samples were obtained by individually adding four hulless barley flours into flour of a wheat variety (Jimai 44, designated as JM) which has very strong gluten. The effects of hulless barley supplementation on gluten structure, dough rheological properties, bread-making properties, and starch digestibility were assessed. The results showed that compared with JM dough, substitution of hulless barley flour to wheat flour at levels ranging from 10 to 40% negatively affected gluten micro-structure and dough mixing behavior, because the cross-links of gluten network were partially broken and the dough development time and stability time were shortened. For the hulless barley-supplemented bread, specific volume was significantly (P &lt; 0.05) increased while springiness was not greatly changed. Furthermore, the hydrolysed starch rate in hulless barley-supplemented bread was decreased, compared with that in JM bread. Importantly, the contents of β-glucan, polyphenols and flavonoids in hulless barley-supplemented bread were 132.61–160.87%, 5.71–48.57%, and 25–293.75% higher than those in JM bread, respectively. Taken together, the hulless barley-supplemented bread has been fortified with enhanced nutritional components, more desirable bread-making quality, and improved starch hydrolytic properties, which shows a great potential to use hulless barley as a health supplement.
