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.

• 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

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 found FTC to be an excellent partner for our company. In particular, it has been especially gratifying to work with Shirl Lakeway. Both creative and accommodating, he worked very hard with us to develop our projects.

I appreciate his commitment to our joint efforts and his open-minded approach. He and FTC have been exceptionally helpful.

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.
