Licorice Firmness

Situation

LicoriceA processor of candy licorice was looking for a way to measure and compare their two types of licorice product, a regular licorice and a soft licorice. Current methods involve sensorial inspections which are very subjective.

This processor did not have a way to objectively measure the difference in texture between their two products. It was important for them to know that the products’ textures were different, and by how much, because for their customers, they want to provide two different, distinct options to choose from.

 

 

Method

Testing was performed with a TMS-Pro Texture Analyzer, a 100 N load cell and a Large Knife Edge. We chose this shearing probe to replicate someone biting into the licorice with their front teeth. The program was written to start at zero, run down to sense top of the product before beginning test to compensate for the difference in height of the samples, run down at 350 mm/min to 7 mm, then return back to zero. The graph to the right shows a vast difference in firmness by the peak forces as well as the area. The regular licorice was more resistant to the knife edge thus the steeper upward slope and higher forces while soft licorice was very soft and did not give as much resistance.

 

Significance and Benefits

  • 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

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.

My first contact with FTC was through buying texture analyzer equipment as my area of interest is Rheology. We faced a problem operating the appliance. The company tried hard to help us through the internet, but the University thought it was better to send me to the company branch located in England. I received a highly advanced training course for 10 days free of charge. They provided me with programs that operate the equipment along with the information needed.

It was a great effort and outstanding support. I would like to thank Shirl Lakeway and FTC for providing me with this opportunity and for his continuous help. Finally, I encourage researchers who are interested in the physical properties of foods and dairy to choose FTC as it is a respectable and dependable company and offers the best deals concerning prices and training with different languages, such as Arabic for the Middle East.

Excellent customer service. Consistently followed up and offered help without asking. Relatively low priced - provides good value. 

Easy to switch different load cells. Used it for 5 lab sessions for 68 students this semester and performed well.
