Texture Analysis SolutionsGreek Yogurt Firmness and Stickiness

Highlights

  • Objective comparative test to evaluate the sensory perception of firmness and consistency of varying fat-content formulations
  • Repeatable method using a software-controlled texture analyzer
  • Precision custom probe fixture to compress and retract from the product, simulating pressing on and penetrating the surface
  • Quantified hardness and adhesiveness texture correlated to firmness, flow, body and stickiness

Situation

A processor of Greek yogurt was looking for a way to measure the difference between their 0% fat and 2% fat products. Current methods involve sensorial inspections which are very subjective.

This processor did not have a way to objectivly measure the difference in texture between their products. It was important for them to know that the products’ textures were very similar, because from a customer stand-point, they do not want a customer to experience a drastic difference in texture between the 0% fat product and the 2% fat product.

 

 

Method

Testing was performed with a TMS-Pro Texture Analyzer, a 250N load cell and an FTC custom-made cylinder probe. The test performed was a back extrusion test. As such, the program was written to start at zero, run down at 100mm/min until it sensed the top of the yogurt, then run into the yogurt 20mm at 200mm/min, then return to zero. The individual cup of yogurt was placed on the standard fixture table so the cylinder probe ran down directly into the product.

The graph to the right shows the curves generated from the test. The first curve is the cylinder probe entering the product. The negative force curves on the bottom show the cylinder retracting from the product and the stickiness on the return home. The test proved positive results for the processor, as there was not a significant difference detected between the textures of the two products.

 

 

Significance

  • Quick and easy test that gives repeatable, objective results that are nearly real time with the processing
  • Allows for more concise control of textural attributes of the product
  • Reduces the possibility of downtime due to a product that does not meet quality standards
