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...

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 +...

Hrušková M., Švec I. (2017): Rheological characteristics of composite flour with linseed fibre – relation to bread quality. Czech J. Food Sci., 35: 424–431. Linseed fibre represents a rich natural source of dietary fibre. Here, we report that the addition of linseed fibre at levels of 2.5 and 5.0% changes the viscosity of wheat flour as well as the rheological properties of non-fermented and fe...

Many varieties of bread are prepared using flour coming from wheat. However, there are other types of flours milled from rice, legumes and some fruits and vegetables that are also suitable for baking purposes, used alone or in combination with wheat flour. The type of flour employed strongly influences the dough consistency, which is a relevant property for determining the dough potential for b...

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...
