Rheological Behaviour of Bentonite—Apple Juice Dispersions

Rheological behavior of the bentonite-apple juice suspensions were experimentally determined within the range of the industrial clarification processes: shear rate 4.3 to 43.1 s-1, pH 4.0-5.0, temperature 10-50°C, bentonite concentration 0.66-2.66 g/L. The experimental data were described with the power law as: τ = Kγ1.56. Temperature effects on the consistency index K agreed with the Arrhenius expression. Although no trend was observed in variation of the Arrhenius model constants with bentonite concentration, these parameters agreed with the frequency factor-activation energy compensation relation.
