yoghurt ice cream (yic) or frozen yoghurt dessert can be regarded as a healthy alternative to plain ice cream. also use of soy derived products in food formulations can lead to the development of products of improved nutritional and health promoting values. yoghurt ice cream was prepared using full-fat soy flour to substitute 55% of non fat dry milk content. product formulation comprised of 12%...

abstract: this paper presents the results of studies concerned with the preparation of fresh food foams based on egg white and various hydrocolloids including iranian gum tragacanth, guar and xanthan gums at different concentrations (0.002-0.040% w/w). the basic physical parameters of the obtained foams such as overrun, stability and morphology of gas bubbles were measured. viscosity measuremen...

In this work, the cone and plate rheological viscometry readings of the sterilized hydrogels of hypromellose 4000 (60 g/L) were investigated by using of the three-parameter Herschel a nd Bulkley powerlaw and the new empirical two-parameter model. In it, the independent variable of shear rate was transformed by logarithm and the dependent variable of shear stress by square root. The two-paramete...

Lead niobium zirconate titanate (PNZT) pastes with tailored rheological properties have been developed for direct-write fabrication of thick-film capacitor elements in highly integrated, multifunctional electroceramic devices. Such pastes exhibited pseudoplastic behavior with a low shear apparent viscosity of roughly 1 10 cP. On aging, the degree of shear thinning and the low shear apparent vis...

We have applied rheological methods for the analysis of ethanol-lysozyme interaction during the process of denaturation and aggregation of the protein. At low concentration of ethanol a destruction of the hydration shell of lysozyme is observed. With the increase in the ethanol concentration a structural transformation takes place. It leads to the formation of a protein aggregate with an elonga...

[1] The scaling of plate tectonic convection is investigated by simulating thermal convection with pseudoplastic rheology and strongly temperature‐dependent viscosity. The effect of mantle melting is also explored with additional depth‐dependent viscosity. Heat flow scaling can be constructed with only two parameters, the internal Rayleigh number and the lithospheric viscosity contrast, the lat...
