A method based on Tikhonov regularization is used to process the volumetric flow rate against pressure drop data of different fruit purees generated by large‐scale flow loops. These data are converted into shear‐rate‐against‐shear‐stress curves. Curves from flow loops with different dia are compared to verify that they are independent of dia. They are also compared against that obtained by a conventional method. Tikhonov regularization will simultaneously extract the yield stress of the purees from the flow loop data. The results obtained by Tikhonov regularization show it to be a very efficient way of processing the flow loop data of rheologically complex foods.
