What is Mecmesin | Texture Analysis?

 

Mecmesin | Texture Analysis is the rebrand of our Food Technology Corporation (FTC) business under our parent Mecmesin brand.

Through our 15 plus year association with FTC, Mecmesin has built up extensive experience in practical food texture measurement.

This rebrand is part of our strategy to emphasise the strength of our capabilities and to grow our food texture analysis business.

Our expertise combined with our cost effective solutions for field, factory and laboratory test environments makes us the ideal partner for your texture measurement needs.

Fish Patty Hardness

Highlights

  • Objective measurement process developed to enable understanding of the impact of manufacturing formulations on texture
  • Repeatable and accurate test method replicating processing elements using a software-controlled texture analyzer
  • Industry-standard fixture successfully applied to fish product to profile the tactility and forming performance of the patty mix
  • Quantified hardness, adhesiveness, viscosity and springiness texture correlated to optimal physical characteristics in manufacture and consumer acceptance

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 into the patty to represent squeezing in the hand and measure sample firmness.

Benefits

Fish cake patty sample after hardness test complete

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.
