The CRISP FRACTURE SUPPORT RIG (HDP/CFS*) This rig is used to measure the fracturability of snack foods and potato crisps (known in some countries as chips) by means of a penetration test.
It allows accurate location and quick alignment of the sample and is used with the Heavy Duty Platform.
A 0.25" diameter spherical probe moves down onto a sample, which is centrally located over a circular support, up to the point of fracture.
Normally a batch of 12 crisps is individually tested and the averages of the 12 maximum peak force and distance at break/fracture values are calculated to give a measure of fracturability.
*Attachments with code prefix HDP/ must be used in conjunction with HDP/90 Heavy Duty Platform.

We can design and manufacture probes or fixtures for the TA.XTplus texture analyser that are bespoke to your sample and its specific measurement.
Once your measurement is performed, our expertise in its graphical interpretation is unparalleled. Not only can we develop the most suitable and accurate method for the testing of your sample, but we can also prepare analysis procedures that obtain the desired parameters from your curve and drop them into a spreadsheet or report designed around your requirements.
For more information on how to measure texture, please visit the Texture Analysis Properties section on our website.
The TA.XTplus texture analyser is part of a family of texture analysis instruments and equipment from Stable Micro Systems. An extensive portfolio of specialist attachments is
available to measure and analyse the textural properties of a huge range of
food products. Our technical experts
can also custom design instrument fixtures according to individual
specifications.No-one understands texture analysis like we do!
