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.

Bulk analysis testing fixtures

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

Nestle purchased a texture system from Food Technology Corporation in 2006. Since then I have recommended the texture system to several vendors in North and Central America. Staff at FTC was able to develop a simple training manual and procedure for the texture system allowing easy training in short period of time.

From purchasing of equipment through to installation and start-up, the level of personal care and service was remarkable. Shirl Lakeway and his staff at Food Technology Corporation are patient and understanding, and are always at our disposal for any assistance. Since we bought the equipment we have had no problems and feel very secure knowing that we can count on FTC for their support and 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.

At the University of Saskatchewan, we are the proud owners of three generations of Food Technology Corporation texture equipment, all of which are still in working condition.

We are looking forward to future innovations from FTC.
