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.

Texture Analysis SolutionsCookie Hardness

  • Objective measurement test method to clearly differentiate between variations in cook profiles during manufacture
  • Repeatable and useful comparison test method using a software-controlled texture analyzer
  • Precision bend fixture to flex and snap the product as a measurable indicator of expected hardness, break strength and brittleness
  • Quantified hardness, cohesiveness and fracturability texture attributes correlated to manufacturing parameters

Specification

hardness testing of a cookie

A speciality biscuit and cookie manufacturer wanted to objectively measure biscuit hardness. Three different samples were evaluated representing:

• too soft
• ideal
• too hard

The markers generated were required to monitor and control a baking line; improve production consistency and provide information for the proactive adjustment of formulation and oven profile to maintain an ‘ideal’ texture.

The snap characteristics of hard and brittle cookies were evaluated using a three-point bend assembly as an indicator of bake profile.

The cookie sample is supported at two points. The travelling beam moves down at maximum speed and snaps the sample creating a single massive fracture.

 

Commercial Benefits

cookie samples for hardness and snap testing

Crispness / Brittleness - Break characteristics can be used to optimise product formulation and handling during manufacture e.g.optimised mix times, oven profiles and starting moisture contents.

Hardness / Break Point - Properties evaluated over shelf-life demonstrate the effectiveness of packaging in preventing moisture penetration from atmosphere in brittle products.

Fracture - Break properties can be used to determine sensory preference during development.

 

Method

hardness testing cookies FTC system capability table

Conditions imposed by the TMS-Pro texture analyzer together, with good experimental design accommodated natural variation in the sample set. A snap test was proposed to break the cookies at speed, creating a single massive fracture.

Sample variation was removed from the three sample sets. Each batch was checked for size, surface properties, breaks and presence of large particulates.

 

Significance

The method followed has demonstrated a clear difference between hard and soft cookie samples. The differentiation between soft and ideal product is much smaller and highlights the need for large sample sets.

The deformation to break in the ideal and soft samples is much greater than that of the hard product.

This is also reflected in the work characteristics where the hard and much more brittle samples fractured and failed very quickly in comparison to their soft counterparts. Repeating this technique is dependent on test speed. It is essential to cause a massive fracture and not propagate small breaks if clear differentiation between samples is to be made.
