3. Impact of processing on product quality
High-pressure homogenization enables significant product modifications such as :
greater stability and homogeneity of dispersed systems;
improved preservation ;
a greater capacity to absorb water and consequently a reduction in exudation;
a change in texture and rheological properties (increase in product viscosity due to an increase in the interface between the dispersed phase and the dispersant phase);
an increase in brightness and a change in color, as well as altered sensitivities to oxidation and enzymatic reactions... (figures 7 and
