The present work confirmed the interest in investigating high-pressure homogenization up to 350 MPa.of food emulsions. Different oil]water emulsions were homogenized at different pressures. Rheological measurements indicated that increasing the homogenizing pressure brought about the emulsions from a shearthinning behavior to a Newtonian behavior, with a great decrease of the viscosity. The flow curves could be explained by the droplet size distributions at 20 and
150 MPa. Therefore, viscosities of emulsions obtained at 300 MPa was difficult to link to light-scattering, measurements. Moreover, the pressure level did not markedly influence droplet size distributions.The high pressure, high shear and relatively high
temperature could also damage some constituents and characteristics of food emulsions, that is why the experimental study needs to be extended to give a more precise and realistic description of emulsion formation in the high-pressure homogenization process. In addition, systematic experiments using well-characterizedemulsions and homogenization devices need to be carried
out.
