Mayonnaise is a food emulsion containing egg yolk as emulsifier and some sort of gum as stabilizer. Iran is a main producer of tragacanth gum in the world which could be a potential replacement for imported gums used in making mayonnaise .The objective of this study was to investigate the possibility of substituting this gum for imported stabilizers in the formulation of mayonnaise sauce. To do...
ABSTRACT: The objective of this study was to investigate the effect of different thermal treatments (20-100°C at five levels for 20 min) on rheological properties of basil seed (Ocimum basilicum) and balangu seed (Lallemantia royleana) gums. Power law model well described the non-Newtonian pseudoplastic behaviour of the seeds gums. The apparent viscosity of balangu seed gum was dramatically aff...

in this study, wasinvestigated the effect of two thickening agents, carboxymethyl cellulose (cmc) and guar on the rheological properties of set fruit yogurt. viscoelastic modulus (g' , g'), apparent viscosity and complex viscosity increased and loss factor decreased by increasing carboxymethyl cellulose and guar content up to 0.2% and 0.06% respectively. however, in the concentrations...
The physicochemical properties of solute in solutions provide valuable information on solute –solvent, solute – solute and solvent – solvent interactions. The intermolecular forces between theliquids molecules and solvent molecules affect the viscosity of the solution. Information regardinginter and intra molecular interactions can be obtained from volumetric, and viscometric data in asolute so...
Magnetorheological (MR) fluids are a type of smart material whose effective viscosity may be rapidly changed (~few ms) in a nearly reversible manner by the application and removal of an externally-applied magnetic field. Conventional MR fluids are composed of micron-scale, ferromagnetic spherical particles (typically 30 to 40 volume percent) suspended in a hydrocarbon, silicone, or aqueous carr...

On 100 sputum specimens selected from patients suffering from chronic bronchitis, bronchiectasis, asthma, and cystic fibrosis total deoxyribonucleic acid (DNA) content has been related to macroscopic type, to total dry weight yield, and to the apparent viscosity of the secretion at 1350 s-1: since DNA may be present, either as fibres or within cells, in one-third of the specimens the contribut...
Shear stress, a mechanical force created by blood flow, is known to affect the developing cardiovascular system. Shear stress is a function of both shear rate and viscosity. While established techniques for measuring shear rate in embryos have been developed, the viscosity of embryonic blood has never been known but always assumed to be like adult blood. Blood is a non-Newtonian fluid, where th...
We derive an expression for the anomalous viscosity in an anisotropically expanding quark-gluon-plasma, which arises from interactions of thermal partons with dynamically generated color fields. The anomalous viscosity dominates over the collisional viscosity for large velocity gradients or weak coupling. This effect may provide an explanation for the apparent “nearly perfect” liquidity of the ...
