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

As a Meat Scientist and program leader for the University of Nevada, Reno, I need to ensure that equipment I use in my lab is reliable, durable, versatile, and accurate. For texture analysis of meats, there are many systems available in the market. Over the last 15 years of my career, I¹ve worked with many of them and had great and bad experiences with different brands.

Last year, I decided to try a different system for my lab, the TMS-Pro Texture Analyzer from Food Technology Corporation. The system has all the attributes I was expecting to conduct texture and shear force analysis in a quick and not complicated way. The customer support provided by them is outstanding and their technicians are always ready to walk me through new procedures and initial set up. If you are looking for a reliable system for food texture analysis and special customer service, the TMS-Pro is the system to go for and the Food Technology Corporation is the one that can deliver the support.

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.

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.
