ABSTRACT<br />
The rheological properties are of great importance in food fluids as<br />
mermelades, salad dressing, soups, sauces and creams [Baudi, 1996]. The<br />
knowledge of rheological properties are very important in the industrial<br />
optimization as pumping, mixing, cooling, drying and others. The usual<br />
viscometers are not good for this systems cause the heterogeneous nature of the<br />
dispersion. With the objective of a best determination of the fluid properties it has<br />
been used the rheometry with mixing principles for heterogeneous systems.<br />
Key words: Non-Newtonian, process viscosity, heterogeneous foods, mixing<br />
principles.
