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

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.

As a seasonal vegetable processor, understanding crop maturity and the accuracy of this measurement is key to staying ahead of crop and knowing when to make the move from value to premium product as harvest time constraints permit.

The TU units provided by FTC give us the accuracy to work to much tighter tolerances, replacing older less accurate analogue equipment which in turn can affect final product grading and profitability.

The units are well designed, very low maintenance and are backed up with a strong support service which will allow them to provide many years of accurate, reliable service.

As a Meat Scientist and program leader for the University of Nevada, Reno, I need to ensure that equipment I use in my lab is reliable, durable, versatile, and accurate. For texture analysis of meats, there are many systems available in the market. Over the last 15 years of my career, I¹ve worked with many of them and had great and bad experiences with different brands.

Last year, I decided to try a different system for my lab, the TMS-Pro Texture Analyzer from Food Technology Corporation. The system has all the attributes I was expecting to conduct texture and shear force analysis in a quick and not complicated way. The customer support provided by them is outstanding and their technicians are always ready to walk me through new procedures and initial set up. If you are looking for a reliable system for food texture analysis and special customer service, the TMS-Pro is the system to go for and the Food Technology Corporation is the one that can deliver the support.
