Influence of oil and emulsifier concentrations on the rheological properties of oil-in-water salad dressing food emulsions
Keywords:Emulsion, Mayonnaise, Sucrose ester, Vegetable oil, Viscoelasticity, Viscosity
The viscous and viscoelastic behaviour of food emulsions containing a mixture of egg yolk and sucrose stearate as a function of oil and sucrose stearate concentrations were studied. Oil concentrations ranged between 40- 55% w/w for emulsions containing 5% w/w sucrose stearate and sucrose ester concentrations varied between 0-10% w/w for emulsions containing 50% w/w oil. steady flow, linear oscillatory shear tests and droplet size distribution measurements were carried out. An increase in oil or emulsifier concentration produced an increase in both the steady-state viscosity and in the viscoelastic functions. The results have been explained on the basis of the relationship between the structural parameters and the rheology of the emulsions studied.
