Module manager: Prof Bronislaw Wedzicha

Taught: Semester 1 (Sep to Jan) View Timetable

Year running 2004/05

Pre-requisites

A BSc degree in chemistry, biochemistry, biological sciences or related science, or chemical engineering.

Objectives

To explain the nature of food as a medium for chemical reactions and the effects of electrolytes, non-electrolytes, pH and dispersed phases on the structures and reactivities of food components; to examine in detail the mechanisms of non-enzymic browning, food additive-food component reactions, and methods of control.

Syllabus

General description of the aqueous and non-aqueous environment in food; specific and general effects of electrolytes and non-electrolytes on equilibria in concentrated systems; mechanisms of reactions of sulphite and sorbic acid with food components; measurements and significance of pH in food; ionisation of proteins; distribution of ions between aqueous and protein gel phases; effects of surfactants on the activity and reactivity of preservatives.
