Determination of the thermal viscosity change characteristics of the skimmed milk powder-water mixture system using a rapid viscometer method - T/ZJATA 0028-2025

Scope

Main technical content: This standard includes the principles of the rapid viscometer test method for the thermal viscosity change characteristics of skimmed milk powder-water mixture systems, reagents or materials, instruments and equipment, analysis steps (including sample pretreatment), data processing, and precision. It describes the rapid viscometer determination method for the thermal viscosity change characteristics of skimmed milk powder-water mixture systems. By using the skimmed milk powder and water mixture system, the viscosity changes under heating, and by continuously monitoring the viscosity change curve of the system with a rapid viscometer, the number of peaks in the viscosity curve, peak viscosity, and final viscosity and other characteristic parameters can be determined. For skimmed milk powders with severe thermal denaturation, no peaks appear in the viscosity curve, or if there are peaks, their viscosity values are relatively low. Based on the changes in the viscosity of the skimmed milk powder and water mixture system during the three-stage test procedure of heating-insulation-cooling, it is determined whether there are peaks in the test curve and the size of the peak viscosity, as well as the final viscosity at the end of the operation. The standard is advanced and innovative, and it conforms to the key directions of group standard construction.
