Dr Jason Hindmarsh PhD, BEng(Hons)

Senior Lecturer

School of Food and Advanced Technology

My general research area is food physics. I enjoy uncovering the molecular processes that drive the physical and chemical changes occurring in food during manufacture and storage. My current area of emphasis is in the application of magnetic resonance techniques to analyse physical and chemical changes in foods and biological materials. The other area is non-newtonian fluids in food engineering. Currently investigating non-newtonian fluid behaviour during spraying drying.

Project Title: Starch-protein interactions in staling

It is well known that starch based foods (breads and baked goods) stale during storage. The consumption of starch based baked snack bars is increasing. In an effort to reduce the their glycemic index (sugar content) they are made with varying levels of additional protein. But it has been found the addition of some types of protein increased the rate of staling of the bars. The objective of this study was to identify the reason for the increased staling rates. Solid-state NMR was used to monitor the starch-protein interactions and moisture migration during storage for model snack bars with the addition of a range of protein types. It was found that proteins that denatured during baking interacted at a higher level with the starch on the molecular scale. This resulted in significantly harder bars. It is recommended that proteins with good heat stability should only be added to starched based baked good.
