Summary module description:

This module discusses food flavour in terms of flavour production, role of flavour, physics of the mouth, the physical chemistry of the mouth and how food processing impacts on flavour.

Assessable learning outcomes:
By the end of the module, learners should be able to:

  • Discuss the origins of flavours in foods (examples of flavours from biological and chemical origins will be discussed)
  • Discuss how food processing will impact on flavours
  • Describe how the mouth behaves and how it impacts on flavour perception and how engineering approaches can be applied
  • Describe how flavours are released and how food microstructures can be designed to modulate release profiles and perceived flavour

Additional outcomes:

Outline content:
The module will cover the following topics:

  • Introduction to flavours and flavour (bio)chemistry
  • The Maillard reaction: benefits and disadvantages, reaction schemes and important factors
  • Food Production: flavour considerations for processing, flavour changes during heating/packaging/storage, methods to combat flavour loss in these processes
  • Physics of Eating: textural properties and breakdown of food, structural influences on breakdown behaviour
  • Encapsulation and Release (flavours and tastes): encapsulation methods and functionality, commercial examples
  • Oral surfaces: soft solid/liquid product interactions with the oral surfaces
  • Taste panels: role of differnt senses, techniques for sensory assessment
  • Flavour and flavour release/measurement techniques: relation to real world release, manipulating flavour release through formulation
  • Lubrication and Soft Tribology: tribology as an in-vitro method for studying oral processing, how lubrication affects perceptions of products
  • Heat and Mass transfer in the mouth: processing of food in the mouth, in-vitro and in-vivo release modelling and kinetics of flavour release
