Tortilla Tear Strength

Situation

Resistance to tear testing of tortillasProducer of corn flour tortilla products needed a way to determine the texture and resistance to tear their products.

To be considered a good tortilla, the product has to be flexible enough to roll up but strong enough to hold a typically hot filling without tearing. Current methods for testing are very subjective and unreliable. They wanted a way to put firm numbers to the properties of their products to replace current subjective measurements.

 

 

Method

Individual samples to be tested were prepared by cutting 6 square samples from the same tortilla to fit into the testing fixture. All testing was done at room temperature using the TMS‐Pro Texture Analyzer. The samples were held in place using a ring clamp (Extensibility Fixture) and punctured through using a 1” inch cylinder probe. The test speed was set to 150mm/min and run to a distance of 35mm. This distance was far enough to have the probe puncture throught the sample.

 

Significance

• Simple test to objectively measure the tear strength of tortillasTortilla resistance-to-tear testing data table

• Software facilitates automatic statistical analysis
• Allows customer to put ‘real’ numbers to their subjective data

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.

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.

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.
