Beef Stick Firmness

Situation

Beef stick bite toughness testingA large manufacturer of beef sticks and beef jerky items was looking for a quantifiable, consistent way to measure and ultimately better control the texture of their product. Current methods involved simple visual inspections and very subjective human sensory evaluation.

The manufacturer had received consumer complaints that some of the beef sticks were too chewy when bitten into. The manufacturer needed to develop a baseline or “standard” for their “ideal” product so that they could compare other products (i.e. too chewy) to it. Before our test, they used sensory analysis alone to determine the bite strength of the product, however, they wanted a method to quantify the data and visualize the difference in the flavors and also difference in an ideal sample and a not ideal sample. A consistent and repeatable method of measuring and therefore controlling the texture is essential.

 

Method

The chart at the bottom exhibits the data collected from running samples of 4 different beef stick products. The graph demonstrates noticeable difference between the 4 flavors. After running many reps on each flavor, the manufacturer could get a “standard” or baseline for that particular flavor. Then, they can compare that number (peak force) to a product that is considered “too chewy”.

 

Significance

  • Quick and easy test that gives repeatable, objective results that are nearly real time with the processing
  • Client will now have a quantifiable way to show differences texture caused by formulation variations

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.

Our experience with FTC has been more than satisfactory, not only for the quality of the equipment you’ve got but for the post selling service that has proved to be excellent.

Any problem that we had, it took nothing more than a simple mail or phone call to have your immediate answer. We want to thank you very much for the quality of service provided.

I appreciate his commitment to our joint efforts and his open-minded approach. He and FTC have been exceptionally helpful.
