Objectives

On completion of this module, students should:
- be able to understand the structure of protein, carbohydrate, and lipids
- be able to understand the functional properties of these molecules in foods and relate structure to finctionality
- understand the nature and properties of enzymes, especially of these oxidising enzymes, proteolytic enzymes, esterases and other hydroltytic enzymes important in foods
- also be able to understand the physical properties of micronutrients and their chemical reactivity.

Syllabus

- Protein structure, types of protein structure in foods, relationship of 2 degree & 3 degree structure to 1 degree structure.

- Amino acid side chain interactions. Food processing affects on protein structure and interactions in food matrix. Functional properties of proteins, denaturation, aggregation and gelation.

- Monosaccharide and polysaccharide structures. Gelation properties. Modification of starch and effects on properties.

- Lipid structure and classification. Crystallisation, crystal structure and polymorphism.

- Physical importance and measurement of solid fat content. Microbiological stability, texture, mouthfeel, taste, spreadability, colour and physical stability of margarine.

- Enzyme kinetics and denaturation. Proteolytic enzymes in foods. Oxidising enzymes and Micronutrients, physical properties and chemical reactivity.
