Sensorial analysis of polysaccharide-gelled protein particle dispersions in relation to lubrication and viscosity properties

The experimental survey presented in this work revealed an interesting set of correlations. The friction coefficient showed a negative correlation with slipperiness, while with other attributes the established relation was below a significant level. Attributes, such as stickiness, sliminess and filmy, correlated with viscosity data of the dispersions within a wide range of shear rates. In addition, a direct relation was found between the powdery attribute and the size of particles present in the dispersions. Moreover, the hardness of these particles seemed to have a strong influence on the steepness of this latter relation.
