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.

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.

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.
