Process validation/Novel preservation systems

Consumer demand for fresher, more natural products has led to the introduction of novel processing and preservation techniques in the manufacture of food. Techniques include high pressure processing, pulsed electric field and cold gas plasma.

Novel processing techniques and preservation regimes require validation for safety regarding food borne pathogens and this is where the Food Safety Centre expertise can be utilised by both industry and government regulators.

For Industry

Examples of projects where IFR expertise have been utilised include:

  • Testing the effectiveness of novel processing techniques such as cold plasma decontamination.
  • Testing the safety of novel preservation systems
  • Analysis of the availability of models to predict bacterial behaviour in foods at temperatures between 40˚C and 60˚C particularly with regards to Sous-Vide cooking
