Abstract:

The present paper research presents the validation of a mathematical model applied for the prediction of rheological behavior of the complex emulsions W/O type (water: 30%; crude, refined soybean oil: 70%). The rheological behavior was investigated for the emulsions realized with two types of industrial oils: S1-crude Soybean oil, S2-refined Soybean oil with different physical-chemical properties: 662 ppm phosphatides 0.14% moisture, FFA-index 0.73, solvent insoluble impurities content 0.17% for S1; 50 ppm phosphatides, FFA-index 0.019, 0.015% moisture, solvent insoluble impurities content 0.004% for S2. The mathematical model for the emulsions’ rheological behavior prediction was correlated with the composition of the complex emulsions W/O with crude and refined soybean oils. The parameters of the mathematical model were identified by the inverse analysis method based on the experimental rheological data values and was realized the validation of the theoretical mathematical model.
