With the objective to study the effect of the difference of potential in the rheological parameters, the study of the rheology behaviour of a liquor “sabajón” was made, submissive a difference of potential between 11 volts and 45 volts in 11 applications with a rank of time between 120 second and 630 seconds. In order to determine the meaning of the results and of finding mathematical the models suitable that they give answer to the correlation of the variables, multiple regression analysis for each one of the dependent variables with respect to the independent ones was made. The drink “sabajón” is a slightly pseudoplastic fluid, with flow number average of 0.815 and to the being submissive different voltages and times from application, this index diminished up to 0.754, becoming more pseudoplastic the flow number, n, diminishes with the application of voltage from 0.815 to 0.754, which allows to conclude that the pseudoplasticity of liquor “sabajon” increases slightly with the electrical treatment. The index of consistency, k, increases with the application of voltage from 0.112 to 0.155, allowing to infer that the viscosity of the fluid (sabajon) increases due to better molecular ordering of the treated sample.
