Objectives
On completion of this module, students should be able to understand the structure of protein, carbohydrate, and lipids. Additionally, students should be able to understand the functional properties of these molecules in foods and relate structure to finctionality. Students should understand the nature and properties of enzymes, especially of these oxidising enzymes, proteolytic enzymes, esterases and other hydroltytic enzymes important in foods. Students should 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.
