چکیده

increasing the nutritional value of bread is important since the enriched product can be used for special target groups such as developing countries or special diets. wheat germ, a highly nutritive part of wheat kernel, is a by-product of milling factories and has the potential to be used for food supplementation. the main aim of this research was to supplement flat bread (barbari) with wheat germ and to study the quality and staling of the resultant bread. therefore, processed (heated at 150°c for 45 minutes) and raw wheat germs were added at the rates of 0, 5, 10 and 15% (w/w) in bread recipe, as separate treatments. using a farinograph, it was found that the dough made with raw germ had less water absorption, lower consistency, and shorter stability time. modeling of the data showed that increasing the germ level had negative correlation with bread volume and softness. such effects were enhanced when raw germ was used. it was found that addition of germ could not delay bread staling; however, it had positive effects on its taste and general acceptability, particularly when 15% processed germ was used.

Effects of Microcrystalline Cellulose and Hydroxypropylmethyl Cellulose on the Properties of Dough and Flat Bread (Iranian Barbari Bread)

There are many reports on the application of different hydrocolloids in the production of leavened breads; most of which show positive effects on bread quality. However, there is little information to prove such effect on flat breads. The main aim of this study was to improve the quality of Barbari dough and bread (Iranian flat bread) in terms of texture, taste and general acceptability of fres...

Effects of Wheat Gluten Hydrolysate and Its Ultrafiltration Fractions on Dough Properties and Bread Quality

Two fractions (50-K and permeate) from a proteolytic hydrolysate (degree of hydrolysis, DH=3.8 %) of wheat gluten were separated using ultrafiltration (UF) membrane with molecular mass cut-off of 50 kDa. The effects of the wheat gluten hydrolysate (WGH) and its UF fractions on the mixing behaviour and viscoelastic properties of wheat dough were presented. The WGH and its UF fractions modified t...

Relationship of Bread Quality to Kernel, Flour, and Dough Properties

Cereal Chem. 85(l):82-91 This study measured the relationship between bread quality and 49 hard red spring (HRS) or 48 hard red winter (HRW) grain, flour, and dough quality characteristics. The estimated bread quality attributes included loaf volume, bake mix time, bake water absorption, and crumb grain score. The best-fit models for loaf volume, bake mix time, and water absorption had R2 value...

influence of hydrocolloids on dough properties and quality of barbari: an iranian leavened flat bread

barbari is a traditional flat leavened iranian bread and one of the most popular breads consumed in iran and some other countries in the middle east. barbari stales very fast and its shelf life is very short. therefore, addition of bread improvers and anti-staling agents, such as hydrocolloids, is a suitable method for extending the shelf life of the bread. in the present study, the effect of v...

Extensional Rheology of Bread Dough

We investigated the extensional properties of wheat flour dough on the Filament Stretching Rheometer (FISER), in which the sample approaches uniform uni-axial extension flow at a constant strain rate over a large portion of the experiment, thereby allowing us to directly probe the transient material function characterizing the behavior of dough in extension. The large dynamic range of this Rheo...
