Book excerpt: The physical, chemical and functional characteristics of food proteins are of fundamental importance to the behaviour of these proteins during processing, storage and ultimately on consumption of the food product, while their biological properties impart nutritional, physiological, biochemical and immunological qualities to the food. Of all food proteins, milk proteins are probably the most thoroughly characterised, chemically, physically and genetically. With the advent of modern analytical techniques, polymorphism of milk proteins can now be studied at the nucleotide level. The discovery of new milk protein gene alleles has enabled animals to be genotyped at birth, allowing for the selection of protein variants associated with specific dairy properties, eg. k-casein in bovine breeds. Expression analysis of native or modified genes with the use of in vitro transcription systems, mammary cell lines and transgenic animals has further improved knowledge of milk protein gene function. Alteration of the primary sequence of milk proteins by modern genetic engineering methods allows for changes in the three dimensional structure to be made, which offers the potential to modify protein functional characteristics. Although the proteins of bovine milk have been widely studies, some minor components of the casein and whey protein fractions have not been characterized to date. Although the significance of such minor components may be negligible, characterisation of such proteins may contribute to a better understanding of the complex milk protein system.
