Peaches (Canned) Firmness

Application

canned peaches firmness can be measured by Kramer shear cellTo measure overall firmness of canned peaches in order to determine differences between different batches of product.

 

Problem

A processor of canned fruits, including peaches, did not have an objective, consistent, repeatable way to measure the firmness of the canned peaches. By sensory tests only, they noticed that some batches of peaches were a lot softer or harder than others. Noticing the variability, the processer wanted an objective instrument that could give quantifiable data that is consistent and a test that is easy and repeatable.

Sample Preparation

Peaches were drained and then put into test cell until test cell was full. That amount was then weighed out in grams. The samples ranged in weight from 181 grams-183 grams.

 

Solution

Fruit quality grading by texture analyzerTesting was performed with a TMS-Pro Texture Analyzer, a 2500N load cell and the CS-1 Kramer Shear Cell. The test program started at zero, then the blades ran down into the test cell, penetrating/shearing the peaches at a speed of 200mm/min and running until the blades penetrated out of the bottom of the test cell then returned back to zero. To the right, the graph shows the differences in firmness between Product A and Product B.

 

Conclusion

The test method proved to be successful at detecting differences between the two batches of peaches. The processor can use this system and test method to compare batches against each other to make sure they are consistent in both quality and texture.

At the University of Saskatchewan, we are the proud owners of three generations of Food Technology Corporation texture equipment, all of which are still in working condition.

We are looking forward to future innovations from FTC.

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.

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.
