Producer 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.
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 TMSâ€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 tortillas
• Software facilitates automatic statistical analysis
• Allows customer to put ‘real’ numbers to their subjective data
