Food for Health Ireland has expanded its portfolio of analytical tools with the integration of a âmetabolomicsâ team at University College Dublin (UCD). Applying this technique to the dairy industry will allow the team to identify changes in a cellâs metabolic profile following treatment with milk fractions. By understanding their precise mechanism of action, FHI aims to strengthen nutritional claims of future functional ingredients.
Part of FHIâs established âIntelligent Milk Miningâ program, metabolomics involves the analysis of the unique chemical fingerprints that certain cellular processes leave behind in biological samples. The products of metabolism are measured at a specific time under set environmental conditions, providing a snapshot of the physiology of the cell. Using a combined approach of nuclear magnetic resonance (NMR) spectroscopy and gas chromatography mass spectrometry (GC-MS), the team at UCD can simultaneously identify and measure hundreds of small-molecule metabolites in one sample.
Dr. Lorraine Brennan, project leader for FHI at UCD, comments: âMetabolomics allows us to examine how milk compounds can alter the metabolism. Through the precise, multivariate analysis of the metabolite environment we can achieve a broader understanding of the exact processes taking place following treatment with milk fractions. Additionally, it enables us to link milk-derived bioactives into metabolic pathways, substantiating future health claims with essential physiological data. Work has commenced at UCD and we expect metabolomics will play a key role in FHIâs work to mine commercially viable bioactives from milk.â
About Food for Health Ireland (FHI)
Food for Health Ireland (FHI) brings together the scientific and commercial expertise of Irelandâs leading research institutions and dairy processing companies: University College Cork, University College Dublin, University of Limerick, Teagascâs Moorepark Food Research Centre, Carbery, Dairygold, Glanbia and the Kerry Group. Supported by EnterpriseIreland, FHI aims to identify bioactive ingredients that can be derived from milk, ensuring that any components found satisfy real consumer needs and accelerate their commercialization.
