Fish Patty Hardness

Situation

Fish cake patty hardness testingA method to measure the hardness of fish cake patties was developed and applied as a predictor of process behaviour.

A major customer identified the texture of fish cakes during manufacture as a critical quality point (CQP) within the production process. Problems had been observed during the forming stage of the production where:

  • product that was too soft produced irregular shaped cakes
  • product that was too hard became brittle and broke on the production line

A method was needed to measure objectively the texture of the fish cake mix before reaching the forming stage - the critical point for optimum processing texture.

Method

FTC technologists worked with the customer to identify key CQP’s and variables within the production process. It was established that the best point to control the physical texture of the finished cakes would be at mixing when water was added to the cake blend.

The FMBRA dough pot set traditionally used in the preparation of biscuit dough for instrumental texture measurements was used to standardise the pre-mix sample and form a 'dummy cake'. Its large compressing plunger replicated the forming process where the cake was produced. A ball probe was penetrated in to the patty to represent squeezing in the hand and measure sample firmness.

Benefits

This method allowed a complete profile of the mix to be established:

  • Firmness - Optimisation of formulation to incorporate maximum water content but maintain consistent product texture.
  • Consistency - Reduce down time in production caused by poor consistency of fish meat mix at point of forming.
  • Elasticity / Yield Point - Improve finished product quality in line with consumer requirements and sensory perception.

Significance

The method developed is quick, simple to follow, and, most importantly, representative of the production conditions imposed during manufacture. Reproducible sample preparation and selection is critical if accurate tolerance bands are to be applied in relation to moisture addition during mixing. Texture data are of greatest value when combined with a good historical knowledge of the manufacturing process.

A preliminary detailed study monitoring the effect of moisture variation at all stages of production is essential. Knowledge must be generated relating to sample temperature and hydration times of potato starch so that tolerances can be set to accommodate all eventualities.

The method developed is ready to be applied within a historical investigation. Full assessment of the
process should be made and tolerances applied at each relevant CQP.

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.

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.

I have found FTC to be an excellent partner for our company. In particular, it has been especially gratifying to work with Shirl Lakeway. Both creative and accommodating, he worked very hard with us to develop our projects.

I appreciate his commitment to our joint efforts and his open-minded approach. He and FTC have been exceptionally helpful.
