Any of the texture analyser range can be used for the product tests listed below.

A selection of special attachments and typical measurements are also shown which are commonly used in this application area. However, this does not show the complete range of attachments available for the testing of petfood products. Test procedures include: compression, puncture/penetration, tension, fracture/bending, extrusion, cutting/shearing.


Typical measurements include:

  • Firmness/Hardness: dry petfoods, biscuits

  • Compressibility/Crush Force: dry petfoods
  • Tensile Strength: dog chews, pack materials, packaging seals
  • Crispness: snacks, biscuits
  • Break Strength/ Snapping Force: dog biscuits, snack sticks
  • Flexibility: wet petfoods
  • Consistency: faecal matter
  • Friction properties: packaging

Ottawa cell

Back Extrusion Cell

Ottawa Cell
Used for determining the 
compressibility, and therefore the 
ease of chewing, of dry petfood 
in a bulk compression test.

Three Point Bend Rig
This rig reveals the break point,
demonstrating hardness and
brittleness or flexibility of dog
biscuits or snack sticks.

Back Extrusion Cell
This test makes unpleasant manual
assessments obsolete by providing
an objective imitative assessment
of faecal consistency.

Petfood testing

Multiple Puncture Probe

Cylinder Probes
Compression of cat food or fish 
pellets tests for product hardness 
or softness which may be vital to 
palatability.

Kramer Shear Cell
Multiple shearing tests overcome
sample variability in meat based 
products.

Multiple Puncture Probe
This probe has an averaging effect
on products of variable particulate 
size or texture without the need for
very high forces to be applied.

Acoustic Envelope Detector

Acoustic Emission and 
Video Playback
Allow the collection of acoustic
data during a test and the
synchronisation of force data with
video frames - of particular interest
for the testing of brittle products.


Application Studies are available for the testing of PETFOOD products using the TA.XT2i, TA.XTplus, TA.XTExpress  or TA.HDplus texture analysers.

In addition, scientific papers have been published which reference the use of the TA.XT2i/TA.XTplus/TA.HDplus in the testing of PETFOOD products.
