In this study, the effect of ultra-high-pressure homogenization (UHPH: 100 or 200 MPa at 25 ◦C),in comparison to colloid mill (CM: 5000 rpm at 20 ◦C) and conventional homogenization (CH: 15 MPa at 60 ◦C), on the stability of oil-in-water emulsions with different oil concentrations (10, 30 or 50 g/100 g) emulsified by whey protein isolate (4 g/100 g) was investigated.

The overall goal of the present PhD thesis was to study some factors related to the choice of emulsifier (whey protein isolate or sodium caseinate) concentration, oil-phase volume fractions (10-50%) and homogenization conditions (100-300 MPa) that could influence physical stability and lipid oxidation in nano/submicron oil-in-water emulsions by using a rotor-startor system (colloidal mill, CM, at 5000 rpm for 5 min) for obtaining the coarse emulsions and stabilized by ultra high-pressure homogenization (UHPH), in comparison to conventional homogenization (CH, 15 MPa).
