[8], at temperatures between 4[degrees]C and 20[degrees]C, the viscosity of GOS syrup with 75% of dry matter extract was correlated to a Newtonian behavior, that is, independent of the shear rate applied, whereas, at 50[degrees]C, a shear thinning effect was observed.

When coated, the plastisol formulation is subjected to a wide shear rates range (up to [10.sup.5] [s.sup.-1]) and a too high viscosity at low shear rate makes its introduction between the knife and the rotating cylinder difficult.
