Fermentation for Food Applications

Release Date: 19th Jan 2022


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.

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.
