Fermentation for Food Applications

Fermentation for Food Applications

Release Date: January


Professional Accreditation: IEMA (as part of MSc)


Lead Organisation: Swansea University


Learn how to develop, refine and scale-up processes for brewing, yoghurt and cheese making, probiotic products; or even to gain value from waste

This module is aimed at anyone interested in developing or refining processes for brewing, yoghurt and cheese making, making probiotic products; or waste valorisation. It begins with an introduction to fermentation processes before looking in detail at the equipment, processes and parameters for successful production. It will  help you to:

  • Outline and specify a controlled operating space;
  • Understand the key process parameters for successful bioreactor operation;
  • Design, optimise and scale-up a bioreactor for a given duty;
  • Identify opportunities within your business which could benefit from the use of bioreactors by comparison with case studies.

The module contains a workshop, details of which can be found here

This module is delivered by Swansea University's College of Engineering and does involve the use of maths, however, one-to-one maths help sessions are available if needed.
