Texture: Measure and analyse properties

Discover the wide range of texture and physical properties that can be measured with a texture analyser.


Abrasion measurement applications using the TA.XTplus Texture Analyser

CRISPNESS/CRUNCHINESS is a property manifested by a tendency when subjected to an applied force to yield suddenly with a characteristic sound. It is commonly the textural property possessed by snacks (potato chips), breakfast cereals, fresh fruit and vegetables and some baked products (biscuits, crackers).

These types of products are usually associated with sharp triangular curves displaying an obvious break point (when tested individually) or produce a 'jagged' multi-peak curve when tested 'in bulk'. The number of peaks produced are as a result of the fracture events that have occurred during the test. Counting the number of force peaks, the average dropoff and measuring linear distance are common calculations applied to such curves. Crispness is usually associated with many small fracture peaks. Whilst a crunchier product may possess the same number of curves the drop from peak to trough will be significantly higher and the linear distance increased accordingly.

The Acoustic Envelope Detector can by employed for any material which produces an audible noise when tested as it captures another dimension (i.e. sound) during the test which can also be analysed and used as a measured product feature. This is usually for brittle materials and the acoustic signal is as a result of a crack, break, snap or failure of some type.

Acoustic output measurement using the Acoustic Envelope Detector

Typical properties that can be obtained from a texture analysis graph:

Rupture point, crispness, fracturability, crunchiness, brittleness, fracture strength, fracture distance, work of failure, breaking strength

The above are only typical examples of fracturability/brittleness measurement. We can, of course, design and manufacture probes or fixtures that are bespoke to your sample and its specific measurement.

Once your measurement is performed, our expertise in its graphical interpretation is unparalleled – no-one understands texture analysis like we do. Not only can we develop the most suitable and accurate method for the testing of your sample, but we can prepare analysis procedures that obtain the desired parameters from your curve and drop them into a spreadsheet or report designed around your requirements.
