How to Measure Consistency
CONSISTENCY is commonly the textural property possessed by dairy products, sauces, syrups and pharmaceuticals lotions (i.e. fluid products). It most often makes use of the back extrusion rig for its measurement. Consistency relates to the 'firmness', 'thickness' or 'viscosity' of a liquid or fluid semi-solid. Stirring a fluid or semifluid food with a spoon or a finger is frequently used by consumers to give an indication of viscosity or consistency.
Typical properties that can be obtained from a texture analyser graph:
Consistency, Firmness, Cohesiveness, Index of Viscosity, Tailing, Stringiness, Shortness

Typical Probe/Fixture used for Measurement:
Cylinder Probes and Platens >>
Moderate/Large Cylinder Probe >>
Back Extrusion Rig >>
The above are only typical examples of consistency measurement. We can, of course, design and manufacture probes or fixtures that are bespoke to your sample and its specific measurement.
Once your measurement is performed, our expertise in its graphical interpretation is unparalleled – no-one understands texture analysis like we do. Not only can we develop the most suitable and accurate method for the testing of your sample, but we can prepare analysis procedures that obtain the desired parameters from your curve and drop them into a spreadsheet or report designed around your requirements.
