Texture: Measure and analyse properties

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

MEASURE TOUGHNESS

Actuation force measurement applications using the TA.XTplus Texture Analyser

BITING/CUTTING FORCE gives an indication of the firmness/hardness of a product. If one considers that if the top front teeth were pulled from a curve-shape into a straight line they would represent a 'knife edge'. Using a knife blade gives a close representation of the biting or cutting action.

TOUGHNESS: whilst Hardness/Firmness is commonly the textural property possessed by most products, the word 'toughness' or 'chewiness' may often substituted for a textural property more associated with the product. Toughness (or 'chewiness') is commonly the textural property possessed by meat, fish and poultry products but also found to be named for baked products such as tortillas, pancakes or pizzas. The toughness is often taken as the total positive area under the curve. This measurement effectively records the total 'work' involved in performing this test. It therefore follows that a higher area value indicates a higher amount of energy involved in performing the test and subsequently is translated as a tougher sample to test.

Look at Hardness as the effort you use to push your shopping trolley round the supermarket. The hardness to push it is dependent on the shopping being added. The more shopping you put in, the harder it is to push, i.e. the greater force you have to apply. The toughness or work is the accumulated effort of the whole journey around the supermarket from empty trolley to the checkout! The descriptions Tenderness and Toughness are not absolute. They have to be defined by agreement between the parties using them. Tenderness maybe the inverse of toughness, as perhaps softness is the inverse of hardness.

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

Work of shear, toughness, biting force, cutting force, hardness, firmness

The above are only typical examples of biting force/cutting force/toughness/chewiness 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.
