Dv 2 pro model viscometer

The evaluation of yogurt sample viscosity was conducted by means of a Brookfield DV‐II + Pro Model viscometer (Middleboro, USA), which was fitted with an LV4 spindle and operated at a rotational speed of 120 rpm. This assessment involved the determination of torque values spanning from 10% to 90%, following the methodology outlined by Saygili et al. (2021 ). The data were captured through the utilization of RHEOCALC 32 Application Software, and the resultant viscosity measurements were expressed in units of millipascal‐seconds (mPa·s).

The apparent viscosity of the yogurts was measured after stirring the product for 20 s, using the Brookfield DV-II Pro Model viscometer (Middleboro, MA, USA) with the appropriate spindle and spindle rotation selection (Spindle no: 3, 20 rpm) at 4 °C according to Brookfield Texture Application Note—Yogurt. The results were measured in mPas, after 35 s of shearing, paying attention to the torque values being between 10 and 100%. The apparent viscosity values of yogurts were recorded using RHEOCALC 32 Application Software (Brookfield Engineering Laboratories Inc., Middleboro, MA, USA).
