Programme overview

Course description

This module is aimed at those working in the agrifood sector (more likely in a technical function) who wish to gain a detailed scientific understanding of the functional properties of materials that determine the physical nature of food products.

The module will offer individual one-day workshops on an array of topics, from raw materials through to production and assessment of the material properties of the food, deemed to be of interest to the food industry. The variety allows the student to select topics which complement their personal interests as well as other modules leading towards an MSc in Agrifood. These topics have been grouped under the following subject areas: Starch, Thickeners, and Extrusion Technology; Lipids and Emulsions; and Non-Sensory Measurement of Food Material Properties.
