The flour from white rice, Arborio (ARF) and Basmati (BRF) varieties, the black rice Negro (NRF) variety, were investigated in this study terms of proximate composition, solvent retention capacity (SRC), thermo-mechanical properties dough bread quality. flours fell into classes with very low amylose content (ARF BRF); NRF had highest contents protein (11.16%), crude fiber (4.75%), ash (1.30%), ...

Purpose: Vitamin D, a fat-soluble secosteroid, has a significant role in bone metabolism and helps calcium absorption in the body. Since vitamin D concentration is altered in fortified foods and dietary supplements, the actual amount of vitamin D may differ from the label value. Methods: In this study, the concentrations of vitamin D2 and D3 of fortified bread sample were analytically determine...

"Elasticity" in bakery is a sensory perception that is felt when the dough is rapidly stretched and released. Elasticity is good when the dough contracts rapidly to approximately its original shape. In another test the baker tries to stretch the dough into a thin membrane (Fig. 82). The formation of membranes with no fissures is attributed to good gluten quality 14 The Role of Gluten Elasticity...

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 ...

Cereal Chem. 70(l):59-63 A capillary extrusion rheometer was employed for detailed investigation coefficient of 2,395 Pa-sec 03 4 . The flow curves, corrected for end effects of the flow behavior of wheat flour-water dough. Dough was extruded and for effect of die diameter on shear rates, were independent of capillary at ambient conditions through capillaries of different lengths and diamdimens...
