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.

 

Trusted by customers across the world

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.
