Food, usually of plant or animal origin and containing important nutrients, is usually modified and made fit for consumption. Thermal analysis allows the of study physical and chemical effects related to temperature changes that occur during the normal food processing cycle, such as boiling, freezing, and drying. A better understanding of these processes is vital in the food industry.

In this Webinar, we will show how thermal analysis is used to analyze food and will present some typical examples of samples measured by DSC, TGA, TMA, or DMA.

The Webinar covers the following topics:

  • Introduction
  • Basic properties of food
  • Typical questions
  • Thermal analysis
  • Industries and applications
  • Instrumentation and applications
    - Differential Scanning Calorimetry (DSC)
    - Thermogravimetry (TGA)
    - Thermomechanical Analysis (TMA)
    - Dynamic Mechanical Analysis (DMA)
  • Summary

A highly regulated industry

Food products are directly linked to public health issues. As a consequence, various international or national regulations and laws exist which provide methods for checking the quality of food products.

Thermal analysis is nowadays an important technique for characterizing different materials in many fields of the food industry.


Thermal analysis of food

The most important effects that can be analyzed by DSC are the melting point, melting range and melting behavior. DSC is used to determine the heat of fusion, purity, polymorphism, glass transition, and oxidation stability.

The main applications of TGA have to do with evaporation, desorption and vaporization behavior, thermal stability, kinetics of decomposition, and compositional analysis.

TOA is used to study the melting point, melting range, and polymorphism using visual observation and recording images and videos.

TMA is normally used to study the expansion or shrinkage of materials and the glass transition.

DMA is the most sensitive method for characterizing glass transition of materials.
