Emulsion stability—experimental studies on simultaneous flocculation and creaming

Studies on the creaming ability of milk

Flocculation and coalescence of micron-size emulsion droplets

We analyze the relative importance of droplet deformation, surfactant transfer and interfacial rheology for the properties and stability of emulsions. The appearance of deformation (flattening or film) in the zone of contact of two interacting droplets has the following consequences. It enhances the importance of the surface forces of intermolecular origin and gives rise to contributions from t...

Effect of xanthan gum on physicochemical properties of whey protein isolate stabilized oil-in-water emulsions

The effect of xanthan gum (XG) addition on physicochemical properties of 2wt% whey protein isolate (WPI) stabilized oil-in-water (O/W) emulsions containing 20% v/v menhaden oil was investigated by measuring droplet size, viscosity, microstructure, creaming profile and oxidative stability. In fresh emulsions, addition of XG at different concentrations did not show any significant effect on the s...

Experimental and clinical studies on fat emulsion for intravenous nutrition.

An experimental and clinical study on DI-22, a fat emulsion for intravenous use and the first such product to be developed in Japan is present. DI-22 consists of linoleic acid, oleic acid, palmitic acid and linoleic acid which is made isotonic with glycerol. The size of the fat particles are 0.8-1.0 in diameter and are uniform in shape. The fluctuation of hemoglobin and hematocrit was the same ...

Fluid shear influences on flocculation Fluid shear influences on flocculation

The tube flocculator is used to study how fluid shear levels affect the settling properties of a flocculated alum-kaolin suspension. FReTA is employed to quantitatively compare the effects of varying fluid shear and hydraulic residence time on the sedimentation velocity distributions and the post-sedimentation residual turbidities of flocculated suspensions formed in the tube flocculator. Resul...
