Understanding how a Texture Analyser works – Measurement accuracy, precision and resolution

A Texture Analyser is a critical tool in various industries, particularly in food, pharmaceuticals, and materials science, for measuring the physical properties of products. Key aspects of its functionality include measurement accuracy, precision, and resolution. Understanding these concepts is essential for interpreting test results correctly and ensuring reliable data.

Measurement accuracy

Accuracy refers to how close a measured value is to the true value. 

Regular calibration against known standards should retain precision and improve accuracy.

Conditions like temperature and humidity can affect accuracy and must be controlled.

Understanding how a Texture Analyser works – Load cells and the measurement of force

All Texture Analysers contain a load cell for force measurement. Load cells are components that convert a mechanical force signal into an electrical signal. They work by deforming in response to the applied force (the deformation being well below the elastic limit of any component materials). In most load cell designs provided by Texture Analyser manufacturers, deflection is measured by strain gauges bonded at points on the load cell, although piezoelectric load cells are also available. The strain gauges provide an electrical signal proportion to the applied load.

Understanding how a Texture Analyser works – Calibration and verification

What is force calibration?

Force calibration is a process used to verify and adjust the accuracy and precision of force measuring instruments and equipment, such as load cells. It ensures that these instruments provide reliable and accurate measurements of force, which is essential in various applications and industries, including manufacturing, quality control, research, and testing.

In force calibration, a reference standard or known force (i.e. a weight) is used as a benchmark to compare and validate the readings of the instrument being calibrated. This reference standard is typically a calibrated force measurement device with a known and traceable force value. Force calibration is essential for ensuring the traceability of measurements.

Understanding how a Texture Analyser works – Key components


A Texture Analyser is an instrument used for measuring the texture or physical properties of materials, such as food, cosmetics, adhesives and pharmaceuticals. At their simplest, Texture Analysers are instruments that use a sequence of movements to compress, stretch or bend a sample. They typically operate by either applying a controlled force to a sample and measuring the resulting deformation or by deforming the sample in a controlled way and measuring the resulting forces.

The textural diversity of food: A sensory adventure

Food texture is a critical aspect of our eating experience, influencing our perception of flavour, satisfaction, and enjoyment. It affects how we chew, swallow, and ultimately enjoy what we eat. For instance, the crunchiness of a snack can enhance its perceived freshness, while a smooth and creamy texture can be comforting and indulgent.

Textural diversity in food refers to the variety of textures we encounter, from the crunchiness of a fresh apple to the creaminess of a ripe avocado. Let’s explore the importance of textural diversity in food, its impact on our sensory experiences, and how different cultures embrace textural variety in their cuisines.
