Texture Analysis in action: the Pizza Tensile Rig

Pizza toughness test using the TA.XTplus Texture AnalyserThe PIZZA TENSILE RIG (A/PT) is comprised of two four-pronged components. 

The upper component fits directly to the loadcell and the lower to the base of the texture analyser. The rectangular shaped test sample is positioned on the attachments using the prongs. 

The tensile force and extension to break the sample is measured and used as an indication of pizza toughness.

Papers using this fixture on a TA.XTplus Texture Analyser have been published, some examples of which are listed below: 

ASHTON, T. J., MICHIE, I. & JOHNSTON, I. A. (2010). A novel tensile test method to assess texture and gaping in salmon fillets. Journal of Food Science, 75 (4), 182-190.
SCHUBRING, R. (2000). Instrumental and sensory evaluation of the texture of fish fingers. Deutsche Lebensmittel-Fundschau, 96 (2), 210-221.
SCHUBRING, R. (2006). Thermal stability, texture, liquid holding capacity and colour of smoked salmon on retail level. Thermochimica Acta, 445 (2), 168-178.

In a departure from its original design use, a new tensile test using the Pizza Tensile Rig provides high levels of accuracy when predicting post-mortem gaping in fish (the appearance of tears or slits within the fillet on handling), providing a valuable addition to the existing pool of instrumental methods for fish flesh quality assessment. This test features in an independent study by the Fish Muscle Research Group, University of St Andrews, and published in the Journal of Food Science.

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.
