Crouton Crunchiness

Specification

Crouton samples for texture analysis

A large processor wanted a way to subjectively measure the differences in their “soft” and “crunchy” products. Current method involves just simple subjective sensory that tends to be inconsistent.

Due to the changes in the incoming raw ingredients, the processing method has to be constantly adjusted to produce a consistent product. The texture of a product like croutons is very important to the consumer. Without the ability to objectively measure this characteristic, it is impossible to control it during processing.

 

Method

It was determined that because of the variation from piece to piece, the Kramer Shear Cell would work best. Instead of testing one crouton at a time, several were tested together so the result is an average of the pieces. This helps to compensate for the variation in the product. For this testing, we used a TMS-Pro Texture Analyzer fitted with a 2500N load cell and the CS-1 Kramer Shear Cell.

This method could also be used with any of FTC texture system. For each replication, 5 grams of product was weighed and place into the shear cell. The pieces were arranged so that they made one even layer in the bottom of the cell. Once the tests were completed, calculations of the peak force and work were made.

Significance

• Simple and objective test that very quickly gives results relating the “crunch” of the product
• Eliminates the need for time consuming subjective evaluation
• Allows the processor to put real numbers to changes in process, instead of just an educated guess

My first contact with FTC was through buying texture analyzer equipment as my area of interest is Rheology. We faced a problem operating the appliance. The company tried hard to help us through the internet, but the University thought it was better to send me to the company branch located in England. I received a highly advanced training course for 10 days free of charge. They provided me with programs that operate the equipment along with the information needed.

It was a great effort and outstanding support. I would like to thank Shirl Lakeway and FTC for providing me with this opportunity and for his continuous help. Finally, I encourage researchers who are interested in the physical properties of foods and dairy to choose FTC as it is a respectable and dependable company and offers the best deals concerning prices and training with different languages, such as Arabic for the Middle East.

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.

I have been using the TMS-Pro mechanical tester in our undergraduate biological materials property course for the past 3 years. The simple setup and operation of the TMS-Pro allows my students to focus on learning the theoretical underpinnings of mechanical properties instead of fighting with a finicky test system.

An added bonus is working with Shirl and his amazing team at Food Technology Corporation. They respond almost immediately to questions and inquiries and are always friendly and helpful.
