It was measure the rheological properties the results of the analysis rheological that all selected mixtures behave non-Newton behaviour "pseudo plastic" with stress subordination has been studying the effect of temperature on the strength of these mixtures and found that heat a large effect on the strength of these foods has been the activation energy account and through these tests found These mixtures are of a good and proper strength.
