About the research project

This research is to understand changes in food flavours that occur during thermal processing and product storage. It will utilise a mechanistic understanding to develop means to counter the changes so that foods can be stored without refrigeration and still have the same consumer appeal as freshly cooked products. Shelf stable foods are more sustainable as they reduce food waste and reduce reliance on the cold chain. Experimentation will utilise objective instrumental measurements of aroma using headspace SPME-GC-MS analysis and an electronic tongue to associate the data on flavour with changes in critical production and storage variables of MATS thermally sterilised foods. Outputs of the instrumental data will be modelled against the kinetic parameters describing changes in food quality and compared with consumer taste panel assessments to assess and predict flavour changes.  The intention would be to identify and manipulate variables to achieve premium flavour quality of MATS shelf stable products to be equivalent to that of freshly cooked foods.

This research is to broaden the economic base from food exports by also producing higher value shelf stable ready meals that can be exported without refrigeration. To be successful it must deliver foods of guaranteed quality that are significantly better than standard retort outputs. To achieve this, it will utilise products from the MATS pilot plant that uses microwave assistance to rapidly sterile meals without excessive temperatures and times that degrade the quality of standard retorted or canned foods. The understanding of how MATS processing, food formulation, and storage variables influence the flavours that consumers consider as premium will drive new technologies to export differentiated premium foods from regional produce. Graduates from this research will be skilled in the development of foods with superior flavours and quality for a career in advanced food product development.
