The rheological parameters of commercial mustards using creep-compliance technique was investigated. Seven commercial mustard not containing mustard seeds, seed pieces or spices made in Poland by different manufactures were studied. Measurements were performed using an rotationally rheometer RheoStress RS 150 (Haake, Germany) in a system of coaxial cylinders (bob diameter 40mm, cup diameter 43.4mm). Curves showing the time-dependent behavior of strain in the time range of 0-100s with a constant shear stress of 1Pa were obtained. The experimental data were described by a four-element mechanical model made up of an instantaneous compliance, Kelvin body, and Newtonian compliance (Burgers model) and by a six-element model made up of an instantaneous compliance, two Kelvin bodies, and Newtonian compliance. A comparison of the curve predicted with the equation and actual data reveals that the Burgers model adequately represents the data, however, better accuracy is obtained using a more complex six parameters model.
