Petfood Testing Attachments

Home > Applications > Petfood Testing Attachments

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.
