Abstract Wheat flour, whole wheat flour, 25 and 50 % rye flour substituted wheat flour blends, 15 and 30 % wheat bran substituted wheat flour blends were supplemented with amyloglucosidase (at 0.000875 and 0.001 %), glucose oxidase (at 0.0003 and 0.001 %) and hemicellulase (at 0.001 and 0.005 %). The effects of enzymes on the extensographic properties of dough and quality characteristics of bread (specific volume, baking loss percentage and final moisture content) were studied. The interaction between type of flour/blend, type of enzyme and dosage of enzyme affected resistance to extension, extensibility and ratio of resistance to extensibility of doughs significantly. The interactions between type of flour/blend, type of enzyme and dosage of enzyme affected specific volume, baking loss percentage and final moisture content of breads significantly. The findings in this study indicated that enzymes can exhibit unexpected effects on dough and bread properties depending on type of flour and dosage of enzyme.

Bread characteristics are dependent upon the chemical composition and fiber content of the wheat flour used. A healthy diet can help prevent chronic diseases, where whole grains and fewer calories from fat are components of a healthy diet. The aims of this study were to determine the centesimal composition of wheat flour samples (whole, refined, and flour blends) along with their farinographic parameters (water absorption, development time and stability) and also to verify the specific volume, crumb texture profile and digital imaging of bread loaves made with 60% whole wheat flour and 3% fat or fat replacer. Increasing the whole wheat flour percentage in the blends also increased levels of protein, ash and insoluble fiber. All the farinographic parameters were also increased. Enzymatically modified starch was found to be an effective fat replacer in whole wheat loaves. The loaves made using fat replacer had the same specific volume and higher cell density as those made with fat, but exhibited different texture profile parameters such as higher hardness value and lower springiness value.

The demand for food products with functional attributes is on the increase worldwide. The present study was aimed at evaluating the effect of supplementing whole wheat flour with 0, 10, 20, 30, 40 and 50% whole green plantain flour on pasting properties of the flour blends, proximate composition, minerals and sensory characteristics of crackers made from the blends. The 100% whole wheat flour served as the control sample. The result showed that the peak viscosity (PV), trough viscosity (TV), breakdown viscosity (BDV), final viscosity (FV) and setback viscosity (SBV) were significantly affected by the level of plantain flour substitution. The 20% plantain flour substitution level recorded the minimum PV (264.00RVU), TV (248.00RVU), FV (531.00RVU) and SBV (263.00RVU) while the 50% plantain flour substituted blend recorded the highest PV (362.00RVU), TV (328.00RVU) and FV (603.00RVU). The control sample recorded the highest SBV (312.00RVU) and least BDV (3.00RVU). The peak times for all the blended samples were the same (7 min) while the time for the control sample was 5 min. There was insignificant difference (P>0.05) in the pasting temperature which ranged from 91.30 – 92.80oC. The crude protein, fat and calcium contents progressively decreased while the ash, crude fibre, carbohydrate, K, Mg, Fe and Zn contents in the prepared crackers progressively increased with increase in the proportion of plantain flour substitution. Cracker prepared from the blend of 80% whole wheat and 20% whole green plantain flours was the most preferred by the sensory evaluation panellists in terms of taste, texture and overall acceptability. It is evident from the study that acceptable crackers of enhanced nutritive value could be produced from blend of 80% whole wheat and 20% whole green plantain flours. The use of flour from unpeeled plantain as ingredient in cracker production would eliminate waste generation and its associated environmental problems.

Three types of special bread (WB: bread with whole-wheat flour, LWB: ‘light’ bread with whole-wheat flour, and MB: bread with multi-cereals) were purchased in the local market, and moisture content was analyzed as well as the following parameters water activity (aw), instrumental texture, and instrumental color of the bread (crust and crumb) using spectrophotometer with CIELab system (n=10). The chroma or C * value and the hue angle were also calculated. The labels of the bread were analyzed according to Resolution-RDC nº 360, which provides information about nutritional labeling of packaged foods. The three breads presented in their composition whole wheat flour and wheat fiber, which are indispensable ingredients for the loaves to be considered "special bread". The compression force applied to cause disruption in the bread was higher in WB (3.88 N) without significant difference with MB (3.79 N) and lower in LWB (2.85 N). The color parameters of the breads showed that WB was darker (lower value of L * = 34.44 in the crust) than the others.

The study was undertaken with a view to explore the use of carrot pomace powder as well as beetroot pomace powder with whole wheat flour in the preparation of high fiber biscuits, to study its effect on the physico-chemical and sensory characteristics of biscuits. The Carrot Pomace Powder (CPP) and Beetroot Pomace Powder (BPP) were prepared through the process of convective dehydration and vacuum drying. All the data obtained were analyzed statistically to determine the level of significance of variation in observations caused by the changes in the biscuits formulations. The carrot pomace and beetroot pomace fortified biscuits contained greater amount of ash, crude fiber and moisture content than control biscuits but lower carbohydrate, protein, calorific value and pH. After fortification of fiber, product was found to be more acceptable in terms of physico-chemical and sensory characteristics.

Abstract Ten percent of the wheat flour in cake-type buttermilk doughnuts was replaced with flours processed from prepress, solvent-extracted peanuts; partially defatted, untoasted peanuts; partially defatted, toasted peanuts; and dry cowpeas. The legume-supplemented doughnuts were prepared with and without soybean flour, which is frequently added to doughnut formulations to control fat absorption during frying. The quality of test doughnuts was assessed by comparison to wheat flour reference doughnuts. Good machinability and frying characteristics were observed in reference and test batters. Legume-supplemented doughnuts scored favorably in sensory comparisons with reference doughnuts and were similar in moisture content. Oil levels of legume flour-supplemented doughnuts were the same or less than that of reference doughnuts and were more acceptable than levels reported in an earlier study which utilized the legumes in the form of meal.

The aim of this study was to verify the influence of the addition of the enzyme xylanase (four concentrations: 0, 4, 8, and 12 g.100 kg-1 flour) on the characteristics of loaf bread made with white wheat flour or whole grain wheat flour. Breads made from white flour and added with xylanase had higher specific volumes than those of the control sample (no enzyme); however, the specific volume did not differ significantly (p < 0.05) among the breads with different enzyme concentrations. All formulations made from whole grain wheat flour and added with xylanase also had specific volumes significantly higher than those of the control sample, and the highest value was found for the 8 g xylanase.100 kg-1 flour formulation. With respect to moisture content, the formulations with different enzyme concentrations showed small significant differences when compared to the control samples. In general, breads made with the addition of 8 g enzyme.100 kg-1 flour had the lowest firmness values, thus presenting the best technological characteristics.
