Fermentation for Food Applications

Release Date: October 2020

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.
