Resumen:
The objective of this work was to relate dynamicrheological data to the pair interaction potentialbetween casein micelles (CM) in concentrated systems. The elastic moduli athigh frequencies (G´inf) were obtained by fitting experimental data from theliterature for CM dispersions at different concentrations using a Maxwellmodel. G´inf values were also obtained using the Buscall model and the pairinteraction potential (U) obtained with DLVO-type theoretical predictions proposedfor CM and for sterically stabilized colloidal particles. It was observed that moduli G´inf obtained fromexperimental data are in agreement with theoretical predictions. Therefore,this methodology allows connecting the dynamic rheometric data with pairinteraction potentials of CM in concentrated skim milk dispersions and it mayhelp to infer about the stability of milk concentrates.
