Psychorheology of ketchup
Štern, Petr ; Pokorný, J. ; Panovská, Z. ; Šedivá, A. ; Vykutilová, T.
A series of twelve ketchups picked up at the Czech markets was analysed at the temperatures 230C and 450C. There were determined the basic rheological characteristics (static yield stress, apparent viscosity, thixotropy, and viscoelasticity) using a rotational rheometer RheoStress 300 (TermoHaake Karlsruhe, Germany) and textural properties using sensor analysis. With the help of correlation of rheological and sensorical data there were derived close functional dependencies with large values of correlation coefficients.
Rheological and sensory properties of cosmetics creams
Morávková, T. ; Štern, Petr ; Pokorný, J. ; Šedivá, A. ; Panovská, Z.
By the analysis of flow curves at low shear rates there was found that flow properties of cosmetic cremes under study correspond to a rheological Herschel-Bulkley model. It was shown that emulsion composition, including small differences in the contents of components, influnces the rheological properties of cremes.
