Texture is an important factor in the consumer acceptance of food, pharmaceuticals and cosmetics. The physical texture also affects processing, packaging and handling in production, plus end customer ease-of-use. Texture analysis is the scientific approach to measuring these attributes to optimize quality and evaluate the effects of ingredients and formulation on factors such as shelf life . Food Technology Corporation's texture analyzers provide the capability to measure and control texture.

Texture Analysis of Tortillas
Manufacturer 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 tortilla testing are very subjective and unreliable. They wanted a way to put steady numbers to the properties of the tortilla texture and firmness 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 food 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 through the sample.
Texture analysis capability for a bakery producer, brings the following benefits:
Simple test to objectively measure the tear strength of tortillas
