Chocolate science and its application to engineering

Chocolate as a material exhibits a plethora of interesting chemical principles, and knowledge of these has great importance for engineers to understand.

The speaker, who has a background in chemistry, will explain some of these scientific principles and how they are used in the engineering world.

The topics covered include:

  • Basic background to making chocolate: dark, milk, white, ruby.
  • Rheological properties (i.e., flow) of chocolate: non-Newtonian rheology (i.e., viscosity changes under force) and particle size requirements. And how considerations of these properties are important in various industries.
  • Hydrophobic and hydrophilic properties (i.e., water ‘hating’ and water ‘loving’) of chocolate. And how colloid chemistry (dispersed solids in solution) is used in paints and building structures.
  • Polymorphism (i.e., different forms) of cocoa butter, how this impacts the final chocolate product, and how tempering is important for glass and steel production.
  • Some interesting chemicals are found in chocolate that have therapeutic and antioxidant properties.

We are committed to having an environmentally responsible event portfolio and we are working hard to plan and implement events which reflect sustainable event best practices.

We are working with venues and suppliers that demonstrate best environmental practices, in particular achieving zero food waste, no single-use plastics, along with recycling and re-use of paper, metal, plastic and glass.

In order to reduce the carbon footprint of the event, we strongly encourage delegates to walk, cycle or use public transport to attend the event.
