Potato softness grading for salad

Application

 

Measuring texture of diced potatoes used in potato salads.

 

 

Problem

 

A processor of diced potatoes was relying on inconsistent, subjective sensory results to measure the texture of their product. Therefore, they needed a quantifiable, consistent and repeatable way to measure their product and implement a standardized range of 'ideal' product.

 

Solution

 

Testing was performed with a TMS-Pro Texture Analyzer, a 2500N load cell and custom-made cylinder extrusion cell (top right picture). The processor sent us 3 products with known texture differences labeled 'soft', 'ideal' and 'hard'. The amount it took to fill the cylinder ¾ full was weighed out and each sample was then made the same size (300 grams). The testing program was written to start with zeroing out load and displacement, running down into the product 85mm at 750mm/min, then returning to its start position. Based on the max force readings, the acceptable range was set from between 1000N and 1500N. Anything above 1500N or below 1000N would not pass as acceptable product.

 

 

 

Conclusion

 

The TMS-Pro texture analyzer system along with this test method proved to detect the differences among the products, proved to be consistent, repeatable and most importantly, the processor now can use the PASS/FAIL function as a standardization tool.

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.

I have been working with FTC for the past 3 years, we bought in that lapse of time 2 texture analyzers with different probes fixtures for all kind of applications at our Monterrey Plant. We have always been able to count on the technical support of FTC who kindly answers our requests in a prompt manner and with the best disposition.

As we continue developing our process to achieve better results at our company, we will for sure rely on FTC for technical support and equipment upgrades that will deliver us the best possible results.
