Tomatoes (Canned Diced) Bulk Firmness

Application

To measure overall firmness of canned, diced tomatoes.

 

Problem

A processor of canned vegetables, including diced tomatoes, did not have an objective, consistent, repeatable way to measure the firmness of the canned tomatoes nor make a standard to compare all other products to.

 

Sample Preparation

Tomatoes 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 204-205 grams.

 

Solution

Testing 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 tomatoes at a speed of 250mm/min and running until the blades penetrated out of the bottom of the test cell then returned back to zero. The graph shows the results of the test.

 

Conclusion

 

The test method proved to be successful at establishing a standard for this diced tomato product where the processor can measure all diced tomato products against this one. If the peak is lower or higher than the standard range set forth by this test, the product will fail. If it is within the set range, it will pass.

Trusted by customers across the world

The University of Arizona’s Nutritional Sciences Food Lab acquired a Texture Analyzer from Food Technologies about 5 years ago. The company has a great product, which is tailored to food needs. 

We have used the Texture Analyzer for both research projects and as a tool to demonstrate to students how food manufacturers can employ objective testing in product evaluation to show how differing ingredients in the same product can affect quality attributes. Its use adds another dimension to the foods labs.

Drew Lambert has been instrumental in helping with set up for testing and providing support whenever there’s a question. He has been a pleasure to work with and is always accommodating with our needs and schedules.  He has even sent us special attachments for special projects.  We couldn’t ask for a better technical support.  Thanks for a great product and great service.

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.

I have been using the TMS-Pro mechanical tester in our undergraduate biological materials property course for the past 3 years. The simple setup and operation of the TMS-Pro allows my students to focus on learning the theoretical underpinnings of mechanical properties instead of fighting with a finicky test system.

An added bonus is working with Shirl and his amazing team at Food Technology Corporation. They respond almost immediately to questions and inquiries and are always friendly and helpful.
