History and usage of texture analyzers

What is texture analysis?

Texture is an important factor in the consumer acceptance of products, especially food. Texture analysis is a methodology used to measure these attributes and as such is able to assess the impact of changes to formulation on processing, handling of other factors like shelf-life.

Benefits and principles

Instrumental methods of assessing texture measurement can be carried out under more strictly defined and controlled conditions. Changes in ingredient levels can cause several simultaneous changes in product characteristics. A main goal of many texture profile analysis studies are devised by one or more mechanical tests with the capacity to replace human sensory evaluation as a tool to evaluate texture analysis.

The principle of a texture measurement system is to deform the sample in a controlled manner and measure its response. Imagine turning a laboratory balance upside down and pressing the balance pan down into the sample.

The force response of the sample would be shown on the digital display moving up or down depending on how far you pushed the balance into the sample – This is exactly how the texture analyzer works.

Forces created during this movement are manipulated to recreate conditions that foods are exposed to when we eat them or process them. This means that we are able to directly measure and predict how a food will perform or feel. Different test applications call for different levels of technology, load capacity, robustness, accuracy and budget. The requirements of the test application directly affect the choice of instrument. For example, high-powered software driven system would be no use for rudimentary field-testing. For this reason FTC provide food technologists with 4 different levels of instrumentation to fit every test environment

Texture Analyzer - TMS-2000 

Adding computer control allows deeper analysis

(NOTE: This model is now discontinued)
The TMS-2000 is a research-grade texture profile analysis measurement system comprised of the TP-6 Texture Press combined with a Windows PC software package.

Designed specifically for food texture measurement, the TMS-2000 software controls the texture press and performs the data processing for results presentation to the operator. Communication and control are accomplished through a standard, reliable network connection so there is no additional hardware to install.
The texture measurement system is capable of up to 3000 pounds-force, and comes with the industry standard Model CS-1 Kramer Shear Cell as well as one FTA Force Transducer. The TMS-2000 can be supplied with or without the PC, and is designed to accommodate FTC Test Cells and Force Transducers. Most older FTC systems can be economically upgraded to the TMS-2000 platform. The system can display results in Metric or Imperial units.

Supplied with: TP-6 Ultra Quiet, Variable Speed and Pressure Texturepress, TMS-2000 software, One FTA Load cell (user specified range), CS-1 Test Cell and Operators Manual.

TMS-Touch Texture analyzer

The TMS-Touch makes quality control testing on a factory floor or production environment a much simpler task at an affordable price.
Texture measurements normally reserved for the laboratory can now be brought to the factory floor saving time, resource and money to instantly determine consistent standards within the raw or finished product.
Performing tests in tension and compression with run-to-load, deformation and time or break detection options, the TMS-Touch combines programmability with very simple operation utilising a keypad interface and a Liquid Crystal Display. Operators on the production floor, for example, can quickly access programs stored in the systems memory and immediately begin testing, whilst supervisors access password-protected levels to set-up and store new test routines and control test settings.

For an all-in-one test system, which can handle the production area environment and provide the freedom to control and create new test routines to suit your requirements, the TMS-Touch offers the ideal solution.

Texture Analyzer - TM-2

Texture analyzers can be placed on the production plant floor
The TM-2 texture press is the latest evolution on the legendary Kramer Shear Press.

The design is sealed against moisture so it can be placed right on the plant floor next to the production line. The TM-2 is maintenance free and is incredibly easy to use.
Load the test cell and with the push of one button the system cycles through the test and displays the Peak Force results on an integrated display.

The texture gage can be set to read in metric or imperial units and the hydraulic press is capable of generating up to 3000 pounds (13,000 Newtons) of force in compression or tension for harder products. The TM-2 texture analyzer will accept the complete line of FTC test cell and load cells so it is versatile as well as rugged.

The TM-DX (now discontinued) variation comes with an integral feature to measure the work done on the sample or "the area under the curve" and an RS-232 link to save readings directly to a Windows based PC.

Supplied with: TX Splash proof Texturepress, TG-4E-I Texturegage with Display in Peak Force and Integral (work), rs-232 port with software, One FTA Load cell (user specified range), CS-1 Test Cell and Operators Manual. The system can be factory set to display results in Metric or Imperial units
