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