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.

The study was conducted to formulate cookies with and without partial replacement of wheat flour (W) with sweet potato (SP) and quinoa flour (Q) blends. Sweet potato flour and quinoa flour were blended in equal proportion and then incorporated at the levels of 20, 40 and 60% by replacing wheat flour to prepare cookies. The cookies formulations were: CI(Control, 100W), CII (80W+10Q+10SP), CIII (60W+20Q+20SP) and CIV (40W+30Q+30SP).The three flour types and the prepared cookies were accessed for their nutritional properties. The prepared cookies were also evaluated for their physical parameters and sensory characteristics. The nutritional profile of cookies increased with increased level of addition of sweet potato and quinoa flour. The protein, fat, fibre and ash content of cookies prepared with 60% replacement of wheat flour with sweet potato and quinoa flour blend were found to be29.3, 71.6, 51.8 and 108.3% respectively, higher than those of control cookies. The spread ratio and the thickness of cookies decreased with the addition of blended flour of sweet potato and quinoa. All the cookies were found acceptable on the hedonic scale in terms of appearance, colour, texture, flavour, taste and overall acceptability. The CII cookies were most preferred by the sensory panel with overall acceptability score of 7.8, only next to control cookies (CI) with a score of 8.

Purpose – The purpose of the present study was to plan with the objectives to optimize and find out the best level of texturized protein from sunflower, soybean and flaxseed on the basis of quality and overall acceptability of the cookies. Design/methodology/approach – Defatted meal from sunflower, soybean and flaxseed was texturized using extruder. Texturized defatted meal of sunflower, soybean and flaxseed was blended at 10, 20, 30 and 40 per cent levels with wheat flour for making cookies using standard procedure. Findings – Functional properties such as water absorption index, foaming capacity and protein digestibility were increased, while water solubility index and fat absorption capacity decreased with increased levels of texturized defatted meal in wheat flour. Spread ratio, sensory, colour and overall acceptability of cookies were negatively affected when level of texturized flour increased as compared with the control. The force required for breaking cookies decreased with increased level of texturized defatted meal of sunflower, soybean and flaxseed incorporation. Cookies with 10 per cent texturized sunflower, soybean and flaxseed flour received the highest sensory scores. The result showed that texturized defatted meals serve as good substitute to wheat flour with increased protein content in cookies production and utilization. Originality/value – The study demonstrated that deoiled cake, a byproduct obtained from sunflower, soybean and flaxseed oil industry, offers great potential for supplementation of proteins in food products.

Cherry Pomace

In this study, the effect of encapsulated sour cherry pomace extract on the physical characteristics of the cookie dough (colour, textural and rheological properties) was investigated. Sour cherry pomace extract encapsulated in whey (WE) and soy proteins (SE) was incorporated in cookie dough, replacing 10% (WE10 and SE10) and 15% (WE15 and SE15) of wheat flour. The dough samples containing encapsulates had the grey-blue colour ( b* values significantly decreased compared to control sample). Due to the presence of anthocyanins, a* values of the dough colour increased significantly with the addition of encapsulates. The addition of soy protein encapsulate increased hardness, resistance to extension and viscosity of cookie dough and decreased deformation compliance ( J), while the addition of whey encapsulate caused dough softness, higher deformation compliance and lower values of viscosity compared to control sample. Values of storage and loss modulus, G′ and G″, significantly decreased when wheat flour was replaced with WE and increased when the flour was replaced with soy protein encapsulate. The addition of soy protein encapsulate resulted in higher cookie hardness.

The use of wheat, sorghum and defatted coconut flour blends in the production of whole meal cookies was investigated with the aim of encouraging the use of sorghum and coconut flour in producing value-added products. Enriched cookies were produced from the blends of wheat flour (WF) and sorghum flour (SF) in varying proportions of 100:0, 90:5, 85:10, 80:15, 75:20, 70:25, 65:30, 60:35 with 5% of defatted coconut flour (CF) added to each sample and were labelled AMUS, BMUS, CMUS, DMUS, EMUS, FMUS, GMUS, HMUS respectively. Cookies with 100% wheat flour (AMUS) served as a reference sample. The proximate, physical, mineral and sensory properties of the cookies samples were examined using standard laboratory procedures. The proximate results of the cookies showed that protein, ash, fat, crudefibre, moisture and Carbohydrate ranged from (9.18–12.25%), (0.88–1.15%), (9.59–11.19%), (2.77–3.74%), (7.10–10.89%) and (64.20–66.71%) respectively. The physical characteristics of the cookies; weight (9.69–18.20 g), diameter (272.0–333.0 mm), thickness (7.72–11.40 mm), spread ratio (23.87–41.09) differed significantly (p < 0.05). However, the sensory results showed that the cookies varied in colour (6.85–7.80), taste (6.90–8.15), aroma (7.10–7.75), crispness (6.65–7.75) and overall acceptability (7.25–8.45). The reference sample had the highest sensory scores for all the attributes except for aroma and crispiness, while cookies with 15% sorghum flour (SF) and 5% defatted coconut flour (CF) incorporation had highest score for crispness and 30% sorghum had highest score for aroma respectively. Based on the parameters evaluated 15% sorghum flour and 5% defatted coconut flour incorporation could be utilized for cookies production owing to its baking potential abilities. However, the high protein, ash and fibre contents of the cookies made with sorghum and defatted coconut flour substitution is very important as this could make a great contribution to the nutrient intake by consumers.

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.

PurposeThis study aims to investigate the effects of incorporating seaweed composite flour on soft roll dough rheological characteristics and quality.Design/methodology/approachIn this study, wheat flour was substituted with seaweed powder obtained from red seaweed (Kappaphycus alvarezii) at varying proportions (100:0; 99:1; 98:2; 97:3; 96:4; 95:5, 94:6, 93:7 and 92:8) and applied in soft roll production. The effects of seaweed composite flour were evaluated in terms of rheological characteristics, proximate composition and physical properties. The sensory characteristics of the soft rolls was evaluated by 40 untrained panellists by using a hedonic scale.FindingsFarinograph analysis of the soft roll doughs showed that the incorporation of seaweed powder promoted an increase in water absorption, development time and mixing tolerance index, whereas it decreased stability time. Analysis of the proximate composition of the soft rolls showed that protein and carbohydrate contents decreased, but moisture, ash and crude fibre contents substantially increased. Dietary fibre increased with the increase in the proportion of seaweed powder added. The specific volume, bulk density and firmness of the soft rolls ranged from 3.01 to 5.48 cm3/g, 0.18 to 0.33 g/cm3 and 1.86 to 20.63 N, respectively. Sensory evaluation results showed that the mean score of sensory attributes decreased as the proportion of seaweed powder added was increased in the formulations. With regard to the overall acceptability, the panellists preferred the soft rolls with the least amount of seaweed powder added. The results of hedonic tests revealed that the panellists' acceptance decreased as higher amounts seaweed powder were added in the formulations.Originality/valueThis study showed that the seaweed powder of K. alvarezii can be utilised as an ingredient to improve the nutrient composition of baked products.

Biscuit formulation was produced from the partial substitution of wheat flour using mangrove fruit flour (MFF) with the addition of an emulsifier. In this study, Pedada (Sonneratia caseolaris) and Lindur (Bruguiera ghymnorhiza) were used as two varieties of MFF. Lecithin and sodium stearoyl lactylate (SSL) was used to enhance the physical properties of the biscuits. An experiment was conducted by replacing wheat flour with MFF at different levels (0%, 20%, and 30%). Margarine, sugars, eggs, glucose syrups, and emulsifiers were added after mixing wheat flour with MFF, baking powder, and milk powder uniformly. Dough sheets were formed and baked on a greased tray at 1500C for 10 to 15 min. The biscuits produced were analyzed for spread ratio, breaking strength, and color (L*, a*, and b*), ranging from 4.13–5.07; 54.07–89.77 N; and 34.70–50.90 L*, 15.17–18.80 a*, and 12.00–28.07 b*, respectively. The analysis of chemical composition showed that the carbohydrate ranged from 90.99–93.60%, protein 4.26–7.12%, fat 0.22–0.59%, ash 0.93–1.75%, and moisture 0.88–1.36%, and the energy value spanned over 391.10–395.33 cal/100 g. Sensory evaluation rating, substitution of 20% with MFF, and SSL addition had the highest acceptability compared to other formulations.

The use of grape peels flour to improve the nutritional value of wheat flour bread has received considerable interest due to their high fibers content and bioactive compounds compared to white wheat flour. The aim of this study was to establish the optimal combination of grape peels particle size (PS) and flour replacement (FR) level with grape peel flour on the dynamic and empirical rheological properties of mix flour dough to develop innovative bakery products. The results obtained highlighted that the small PS resulted in increased Farinograph water absorption and Amylograph peak viscosity and decreased dough development time. The FR showed a significant (p < 0.05) effect on Rheofermentometer parameters. The dynamic moduli increased when increasing FR and decreasing PS, while the loss tangent decreased with FR increase. The white wheat flour with 3.80% small particle size of GPF was found to be the best formulation in order to achieve the desirable dough rheological properties.
