The aim of this research was to determine existence the correlation between chemical and certain rheological quality parameters different wheat flour samples bread produced from them. Three type 500, which were as experimental in industrial conditions, analyzed. analysis composition (content water, ash, ash on dry matter, fat, protein, starch) farinograph (farinograph water absorption, dough de...

Deformability modulus, hardness, cohesiveness and adhesiveness of cassava dough reconstituted from precooked flour were evaluated using a lubricated compression test and texture profile analysis. Cassava parenchyma processed under different cooking conditions and left at either -5oC or -20oC for 24 h was used to make flour, which was reconstituted into dough. As temperature decreased to -20oC d...

The effect of protein composition and content on the characteristics and properties of laminated baked products has been studied for a long time. However, there are no flour quality parameters related to its suitability to produce yeast-leavened laminated salty baked products. The relationships among flour characteristics, laminated dough pieces and baked products were studied in order to estab...

X-ray tomography is a relevant technique for the dynamic follow-up of gas bubbles in an opaque viscoelastic matrix, especially using image analysis. It has been applied here to pieces of fermenting wheat flour dough of various compositions, at two different voxel sizes (15 and 5 μm). The resulting evolution of the main cellular features shows that the creation of cellular structures follows two...

BACKGROUND The effects of mixtures of reducing and oxidising agents on the rheological characteristics and quality of wheat flour dough and the sensory characteristics of buns were studied. RESULTS In chemical analyses, no differences between control dough and doughs with individual mixtures of additives were found. Rheological measurements showed that increasing addition of L-ascorbic acid +...

Cell-surface engineering (Ueda et al., 2000) has been applied to develop a novel technique to visualize yeast in bread dough. Enhanced green fluorescent protein (EGFP) was bonded to the surface of yeast cells, and 0.5% EGFP yeasts were mixed into the dough samples at four different mixing stages. The samples were placed on a cryostat at -30 degrees C and sliced at 10 microm. The sliced samples ...

This study presents the action of an exogenous enzyme: protease in different dosages, in the bread dough. The determination of the rheological characteristics of the dough is obtained by alveographic method. The addition of proteolytic enzymes allows adjustment of the rheological characteristics of dough according to the needs of the technological process. The specific effect of proteases on th...

The rising of bread and the quality of the baked loaf depend upon the nature of the dough and especially upon such of its properties as tenacity, ductility, and elasticity. These properties are hard to define theoretically in this complex colloidal system, but they are, as we have found, related to viscosity or to whatever may determine the resistance of dough to stirring and to flowing through...

It is known that crystalline amylopectin of starch plays a role of resistant starch. Although crystalline amylopectin of starchy food melts almost completely during its heat-processing, the melting may be prevented by a pre-dehydration treatment, because melting temperature of the crystalline amylopectin increases with a decrease in the water content of starch. In order to some insight into the...
