are textural properties that are generally on the same property
spectrum. A soft product is one that displays a slight resistance to
deformation, a firm product describes one that is moderately
resistant to deformation and hardness describes a product which
displays substantial resistance to deformation. However, it is also
found that depending upon the product industry one of these words may
be more favourable or pertinent to a particular product.
The terms Firmness, Hardness
and Softness are so broadly used that they can be obtained by
a variety of different test types. In certain cases, the product has
limitations of presenting to the texture analyser for testing. For
these reasons, a compromising solution may have to be found to
optimise the testing of the required product property.
The test type is chosen according
to the size, form, homogeneity etc. of the sample and can therefore
be derived from a single piece compression, bulk compression,
penetration, extrusion or cutting tests as is most appropriate.
Whilst performing one of these tests it is not uncommon to be able to
obtain a number of other textural parameters that are also possessed
by the product.
The above are only typical
examples of firmness/hardness/softness
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.
