Texture: Measure and Analyse Properties


Measure Cohesiveness


Cohesiveness measurement applications using the TA.XTplus Texture Analyser

COHESIVENESS is the tendency of a product to cohere or stick together. The intermolecular attraction by which the elements of a body or mass of material are held together determine its cohesiveness. It is related to the internal stickiness of a product and is usually determined by measurement of the amount of force to remove an item from the product mass.

High cohesiveness may be favourable for products such as paint where easy removal of a brush from the main mass of paint needs to be a clean separation and without the tendency to extend from the surface of the mass to the brush for a considerable distance. However, low cohesiveness may be a favourable property of a product such as honey or syrup where considerable extension of the product from its main body of material is accepted.


Typical properties that can be obtained from a texture analysis graph:

Consistency, firmness, cohesiveness, index of viscosity, tailing, stringiness, shortness.

The above are only typical examples of cohesiveness 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.
