Caviar Softness

Situation

Caviar softness testing with a compression fixtureA supplier of fresh fish products wanted an objective method that could reliably determine quality levels of the caviar throughout the harvesting season.

Textural properties of the product have been found to be a key characteristic in the determination of quality. The customer had no real way to measure these differences and therefore, no real data to back up whether the product maintained a certain level of quality.

A compression test was used to provide valuable data regarding the quality of caviar.

 

 

Method

FTC offered a compression test solution that could be performed using small amounts of caviar placed upon FTC’s standard fixture table.
With a speed setting of 75 millimeters per minute, the sample was compressed using a 38.1mm (1.5 inch) Perspex precision probe cylinder.

The degree of compression was determined prior to testing, enabling the product to rupture, but stop before contact of the Perspex cylinder and the tables surface. Calculations were then performed to measure the peak force encountered for each test replication.

 

Benefits and Significance

• Simple test to objectively measure the ‘pop’ of the caviar
• Software facilitates automatic statistical analysis
• Enables customer to put ‘real’ numbers to their sensory information

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.

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.

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.
