DESCRIPTION The study-unit will deal with the following topics: Sugars, Mono-, Oligosaccarides, Sugars as solids / in solution, Decomposition, Polysaccharides, Starch, Pectins, Seaweed Polysaccharides, Cellulose, Hemicelluloses & Fibre
Gums, Lipids, Fatty acids – structure & distribution, Conjugated linoleic acids, Essential fatty acids, Reactions of unsaturated fatty acids (hydrogenation, margarine & trans fatty acids), Rancidity, antioxidants, Triglycerides (melting & crystallization, cocoa butter & chocolate, interesterification), Polar Lipids (milk fat, cream & butter, phytosterols), Proteins, Amino acids & essential amino acids, Protein structure, Food protein systems (milk, cheese, egg, meat & bread), Enzymes and their behaviour, Water, Structure, Interaction with food components & materials and Binding.

Study-unit Aims:

This study-unit aims to provide students with knowledge of:
- The structure and properties of proteins, lipids and carbohydrates in food;
- The effects of processing and storage on these food components;
- The relevance of food components to the properties of selected food commodities.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:
- State the structures and discuss the properties of proteins, lipids and carbohydrates;
- Discuss the effects of processing and storage on these food components;
- Relate the composition of selected food commodities to their properties and vice versa;
- Describe enzyme action and how enzyme process can be inhibited.

2. Skills:

By the end of the study-unit the student will be able to:
- Derive kinetic data of enzyme behaviour from graphical analysis;
- Analyse linear graphs.
