Summary
Oxidative damage is a major problem for dairy industry as it can occur to a significant extent during the processing and/or
storage of milk, and results in significant wastage. Due the high abundance of proteins, ~30% of the dry mass of whole milk,
these represent one of the most abundant targets of damage. Protein oxidation can have a direct impact on the nutritional
value of milk and the consumption of highly oxidised proteins may have deleterious consequences for human health. This
project will provide an improved understanding of the degradation pathways of the most abundant milk proteins (caseins),
the micelle structures that these proteins form, and the key drivers of these reactions. To address these aims, this project
will: (1) investigate the oxidation of casein micelle (CM) mediated by the most relevant oxidative sources generated during
milk processing and storage, and (2) determine the consequences of CM oxidation on their nutritional value (i.e. loss of
parent amino acids) and the biological effects (i.e. decreased digestibility, toxicity to human cells). The approaches to be
used in this project include analytical, biochemical and biological techniques (i.e. liquid chromatography, SDS-PAGE,
western blotting, mass spectrometry, electron microscopy, cell culture models). The project is of interest to the European
community as milk and dairy products represent one of the most consumed food materials, with health and nutrition claims
for these products based on the presence of specific materials, such as proteins. It is therefore critically important that these
claims are justified and correct. This project will provide important new knowledge, as there are currently no data available
as to the pathways responsible for CM oxidative modifications. Such data is a pre-requisite to the development of lessharmful
industrial milk processing methods. The project will also validate new methods to examine the nutritional quality of
milk and dairy products.
