This suggests that microfluidisation increased the proneness of the stirred yoghurts to shear-induced structural breakdown with decreased recovery of the structures that were broken down during shearing. However, their downward flow curves exhibited higher shear stresses, at all shear rates, than did both downward and upward flow curves of low-fat control yoghurt, indicating that, even with structural breakdown due to shearing, low-fat yoghurts from microfluidised milk still possessed higher viscosity.
