Food products are complex systems and their rheological properties undergo changes over time, which are disadvantageous. Those changes can be searched into while measuring thixotropic properties of food. This paper presents methods of measuring thixotropic properties of food products, which appear effective when qualitatively and quantitatively determining the phenomenon of thixotropy. No procedure exists that could make it possible to unmistakably determine thixotropic properties; however, owing to the methods presented herein, the rheological parameters can be determined as can be, to a certain extent, the stability of food products.
