Bulk analysis test methods

Animation of compression shear cell bulk analysis method

A bulk analysis test method is used when it is not practical or representative to test an individual sample as a whole or component piece - the product sample is tested “in bulk”. Particulate products (e.g. reconstituted meats), or foodstuffs which contain small elements in an individual serving or mouthful (e.g. rice or beans), lend themselves to being analyzed by this method. The procedure then applies compression, extrusion and shear - often in combination - resulting in high forces. The most widely-used fixture is the Kramer shear cell.

See FTC's bulk analysis test method capabilities.

Test procedures

The procedure uses a lower accessory contain the bulk product and an upper component plunger or blade moves downwards to compress and/or shear. The deformed sample extrudes, either forward through the bottom of the container cell, or backwards around the upper accessory.

The peak compressive force is an important measurement, the data is an average for the overall texture, and the shear cell application is very illustrative of mouthfeel – accurately simulating the biting and chewing of food.

Trusted by customers across the world

The University of Arizona’s Nutritional Sciences Food Lab acquired a Texture Analyzer from Food Technologies about 5 years ago. The company has a great product, which is tailored to food needs. 

We have used the Texture Analyzer for both research projects and as a tool to demonstrate to students how food manufacturers can employ objective testing in product evaluation to show how differing ingredients in the same product can affect quality attributes. Its use adds another dimension to the foods labs.

Drew Lambert has been instrumental in helping with set up for testing and providing support whenever there’s a question. He has been a pleasure to work with and is always accommodating with our needs and schedules.  He has even sent us special attachments for special projects.  We couldn’t ask for a better technical support.  Thanks for a great product and great service.

I have been working with FTC for the past 3 years, we bought in that lapse of time 2 texture analyzers with different probes fixtures for all kind of applications at our Monterrey Plant. We have always been able to count on the technical support of FTC who kindly answers our requests in a prompt manner and with the best disposition.

As we continue developing our process to achieve better results at our company, we will for sure rely on FTC for technical support and equipment upgrades that will deliver us the best possible results.

Excellent customer service. Consistently followed up and offered help without asking. Relatively low priced - provides good value. 

Easy to switch different load cells. Used it for 5 lab sessions for 68 students this semester and performed well.
