During new product development manufacturers must consider the effect of these processes on the structure of surimi with regard to toughness.
In particular, heat applied during processing can substantially change the structure and increase the toughness of surimi, producing a fish-mince with a leathery feel.

When force is applied, brand B also ruptures at a greater distance (distance at failure). In consumer terms, this means that sample A is more desirable for soft shell-fish like crab, whereas B would be more suited to firmer texture products such as shrimps.
The advantages of a multiple blade fixture, such as the Kramer Shear Cell shown in Figure 6, are that it can sense anisotropy and the test sample mass and area are large such that the influence of local irregularities is reduced.

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.
