Prof Julian Heyes PGDipDevStud, PhD, BSc(Hons)

Head of School of Food and Advanced Technology

School of Food and Advanced Technology

I am the inaugural Head of the School of Food and Advanced Technology. The new School resulted from a merger between the School of Engineering and Advanced Technology and the Massey Institute for Food Science and Technology. I am also Professor of Postharvest Technology. My strategic research interests lie in connecting science to growth of the New Zealalnd bioeconomy, based on high value food, fibre and fuel products and technologies. I also work on horticulture in developing countries and horticulture for health.

Project Title: Metabolomics for health

'A diet rich in fruit and vegetables has been shown to reduce the risk of coronary heart disease': this is one of the few pre-approved high-level health claims that is permitted under New Zealand and Australian food labelling legislation. But what is it in our fresh fruit and vegetables that helps to keep us healthy? We know that the list includes vitamins, minerals and nutrients; and we know that dietary fibre has a huge role to play in maintaining good health. But there are also tens of thousands of phytochemicals: small bioactive molecules that trigger protective responses in our body and may help us fight all kinds of disease. Historically research in this area has been slow as we focus on one chemical at a time. In this project we adopted a non-targetted 'metabolomics' approach, measuring 'everything that moves' in simple carrot extracts using nuclear magnetic resonance, and then we let the computer tell us what was different between particular samples. This approach can be used to screen (for example) extracts from different cultivated varieties of a single vegetable that are known to have different "bioefficacy". This preliminary study was carried out jointly with Plant & Food Research and has led to ongoing research trying to match particular carrot varieties to particular health outcomes.
