Clam Firmness

Situation

Sample of clams in their shellsTwo samples of chopped, processed, and canned sea clams were submitted for texture evaluation.

Sea clams are naturally tough right out of the ocean, therefore, companies must treat them to soften them up to sell to consumers. They need to be able to measure the softness of the clams after treatment. They also need this way to be repeatable, consistent and quantifiable.

 

Method

Chopped sea clams on the shear test standTesting was performed with a TMS-Pro Texture Analyzer, a 2500N load cell and a CS-1 Kramer Shear Cell. The program was written to start at zero, run down at 300mm/min into the product and completely through the bottom of the test cell (90mm) then return to zero. The samples were drained and weighed into 40 gram portions (about 5-6 clams). No sorting of the individual pieces was done and the portions were randomly extracted from the drained product.

 

Significance

Using the TMS-Pro texture analyzer and the compression/shearing test method of a bulk product sample proves to be a good indicator of the softness of the clams and detects a different between products after treatment. This test could be used either as a benchmark for the “ideal” texture of the chopped clams or can be used to detect differences between different batches before they are canned.

Trusted by customers across the world

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.

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.

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.
