The ability of trifoliate hardened-yam flours to partially substitute wheat flour in food formulations was assessed. Three varieties of hardened-yam flour were incorporated in wheat flour in proportions of 0, 10, 20, 30, 40, and 50% (w/w). Samples were evaluated for protein content, Zeleny sedimentation index, Hagberg falling number, functional properties (WAC, WSI, and OAC), and some rheological properties including dough rupture pressure (P), extensibility (L), stability (P/L), and deformation energy (W). Results showed that trifoliate hardened-yam flours do not have acceptable baking properties as pictured by the low Zeleny sedimentation index and the low Hagberg falling number. Protein quality (Zeleny index, 31) of wheat flour helped to compensate gluten deficit of yam flours, but the amylasic activity determined by the Hagberg falling number could not be adjusted, which resulted in a loss of extensibility (L) of the paste at 10% substitution. Multivariate analysis of experimental data regrouped wheat flour and all wheat/hardened-yam treated with kanwa composite flours in one homogeneous cluster. Although wheat/hardened-yam treated with kanwa composite flours had physicochemical and functional properties similar to wheat, the inadequate diastasic activity makes them inappropriate for bread making, marking the strongest influence of that parameter.

The objective of this work was to find the suitable incorporation ratio of D. praehensilis flour into wheat flour in order to obtain appropriate bread. All incorporation reduced bread making potential as wet gluten, dry gluten, gluten index and gluten water binding capacity. These values decrease significantly from (28.4 % to 21.7 %), (10.3 % to 7.54 %), (95 to 88 %) and (18.1 to 14.16 %) respectively for wet gluten, dry gluten, gluten index and gluten water binding capacity. The yam flour incorporation reduced the dough rising potential and the final bread volume. The specific volume decreased from 3.26 to 1.37 cm3/g. During dough fermentation, highest volume values were ranged from 135.45 cm3 to 100.06 cm3, respectively from control (WF) to WYF-25 flours. Flours damaged starch content increasing from 21.8 % to 28.9 %, was responsible of the Hagberg Falling Number reduction related to increase of amylase’s activities. The Falling Number of composite flours was ranged from 327s to 357s, compared to control flour dough (362s). This induced the increasing of dough hydration from 62 % to 82 %. Increase in dough Tenacity (from 103 to 222 mmH2O) and P/L configuration ratio (from 0.93 to 7.93) were noticed. The sensory evaluation showed that below 10 % of yam flour substitution to wheat flour the final bread crumb colour, aroma, taste, and overall are acceptable by consumers.

Starch Gelatinisation

Recently, in 2005, a new method for monitoring the rheological properties of the dough on the entire technological process of bread making became available through Mixolab at an international level. This laboratory equipment has amazing possibilities for the research and development, enabling a complex analysis of flour. It allows the analysis of flour proteins quality (water absorption, stability, elasticity, weakening), the analysis of starch behaviour (gelatinisation, gelatinisation temperature, the modification of its consistency on additives addition) and the analysis of enzymatic activities (proteolytic, amylolytic). The objective of this study is to establish a relation between the alveograph, Falling Number, and Mixolab values. Sixty flours, collected around the Romanian country, were analysed simultaneously on alveograph (standard protocol), for the Falling Number, and on Mixolab ("Simulator" and the standard option "Chopin+" protocol). A selection of principal factors based on the Principal Component Analysis (PCA) was applied which allowed the building of an efficient predictive model for each parameter. There were significant correlations between most of the Alveograph parameters: maximum pressure (P), deformation energy (W), extensibility (L), alveograph ratio (P/L) and Simulator Mixolab stability. Using the Mixolab standard option "Chopin+" protocol a close association was found between some Mixolab parameters: stability and protein weakening (C2, difference of the points C1–C2 abbreviated C12) and the alveograph values (P, W). From the point of view of the correlations established with the Falling Number index, very good results were obtained with the parameters obtained with Mixolab that measures starch gelatinisation (C3, difference of the points C3–C2 abbreviated C32), amylolytic activity (C4, difference of the points C3–C4 abbreviated C34), and starch gelling (C5, difference of the points C5-C4 abbreviated C54).

Parameters of Wheat Flour, Dough, and Bread Fortified by Buckwheat and Millet FloursThe composite flours were created from basic wheat flour and from buckwheat and millet flours used as additives in the weight ratio of 5-30%. Basic technological parameters of flours (ash content, wet gluten, gluten swelling, sedimentation index, falling number), rheological properties of dough, and sensory parameters of baked bread loaves (weight, specific volume, aroma, taste, structure) were studied. Additives influenced all traits of flours, doughs, and baked breads. From the technological and sensory points of view, baked breads with the addition of buckwheat were accepted up to the addition of 20% and breads with millet up to 5% (even though taste and flavour were accepted up to 15% addition).

The aim of this research was to produce bread from composite flours (fermented cashew kernel/wheat), determine their physicochemical and sensory properties. The Hagberg falling number (FN) and rheological properties of wheat flour replaced with fermented cashew kernel flour at 10, 20 30 and 40% were evaluated. The physical properties and proximate composition of loaves were determined. Also sensory characteristics of breads were evaluated. Results showed that the substitution of wheat flour with fermented cashew kernel flour negatively impacted the rheological properties and increased the falling number. Thereby, composite flours obtained from wheat flour substitution with fermented cashew kernel flour at 10 and 20 percent levels were retained for bread production. The weight, volume and specific volume of loaves varied from 208 to 229 g, 433 to 657 cm3 and 1.80 to 3.20 cm3/g respectively. The crude protein, fat, crude fibre, moisture and ash contents of the composite breads increased significantly (P<0.05) with increase in the proportion of fermented cashew kernel flour. The carbohydrate contents were observed to decrease significantly (P<0.05) from 38.08 to 56.18% with increase in the percentage of the cashew kernel flour incorporation. Sensory evaluation of the bread samples showed that substitution level of 10% fermented cashew kernel flour produced bread that was acceptable to the consumers whereas at 20% were neither like nor dislike. Therefore, it is recommended to use a level of substitution of wheat flour with fermented cashew kernel flour not exceeding 20% for bread production.

Most snacks are prepared from basically cereal flours which are nutritionally inadequate. There is the need to complement the nutrient content of these snacks by varying the food sources. Chin-chin snacks were produced from composite flours of Maize, soybean and OFSP with the following formation; sample A (50%: 25%: 25%), B (25%: 25%: 50%), C (25%: 50%: 25%), D (0%: 50%: 50%) and E (50%: 50%: 0%). Wheat flour (100%) served as the control F. The flour bends were analysed for functional properties while the chin-chin snacks were analysed for their nutrient and sensory qualities. The result of functional properties of the flours showed that bulk density of wheat flour (F) was the highest (0.746 g/ml). OFSP flour enhanced the water absorption capacity of the flour blends. Flour blends with soybean recorded higher values in foam capacity (11.20 - 22.55%). In proximate composition, the moisture was low (3.80 – 4.80%) in the chin-chin. Higher fibre content (2.60 - 4.20%) was obtained in samples containing higher proportion (50%) of OFSP. Samples D (19.38%) and C (18.80%) with higher soybean, recorded higher protein values. The mineral and the vitamin contents of snacks from composite flours were higher than that of the control F. Vitamin B1, B2, B3 and β-carotene contents of the snacks were enhanced by OFSP. The sensory evaluation showed preference for snack F (100% wheat flour) followed by snack A (50% maize, 25% soybean and 25% OFSP). However, improved nutrient dense chin-chin snacks were produced from the composite flours.

Aims: Malnutrition among all ages is still a persistent problem in India, especially in areas where the poor largely depend on rice and wheat staples with limited access to diverse diets using underutilized foods.  This study was conducted to nutritionally enhance traditional food products like roti and lapsi utilizing suitable composite flours based on amaranth, soybean and wheat without affecting their sensory quality. Study Design: Different combinations of amaranth, soybean and wheat flours were made to suit the quality characteristics of roti and lapsi. Place and Duration of Study: Department of Foods and Nutrition, G. B. Pant University of Agriculture & Technology, Pantnagar (India), between January and June 2016. Methodology: The sensory evaluation of food products and estimation of nutritional composition of composite flours was done using standard procedures. Results: The composite flours having 25% amaranth, 15% soybean and 60% wheat flour and 25% amaranth, 10% soybean and 65% wheat flour were found to be most acceptable sensorially and were significantly superior to their control counterparts for protein, ash, fibre, carbohydrate calcium and iron content (p=.05). Conclusion: Roti made from amaranth and soybean incorporated composite flours with better protein quality and low available carbohydrates and physiological energy almost same as control would be better diet alternative to diabetic and overweight patients whereas lapsi may be effectively used as supplementary food. Many other traditional food products like laddoo, halwa, puri, parantha, burfi etc. may also be made from such composite flours.

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.
