About the research project

This project is to research factors that govern the quality of products that can be produced by 3D food printing for valorisation of food grade seconds and wastes. Regionally, lower grade food products such as mechanically recovered meats and second grade fruit and vegetables could be stabilised into feed streams for future food printing or other restructuring technologies. However, high-throughput commercial applications of 3D food printing will require feed streams that are stabilised and optimised for producing quality printed foods. Formulation, combined with food preservation systems, such as microwave assisted thermal sterilisation (MATS) or flow-through UHT will be required to make shelf-stable bulk food ingredients for 3D-food printing production lines.

This project will characterise the critical variables for stabilising the texture, colour and flavour of products such as animal proteins and fruit and vegetable powders or purees for use as shelf-stable solutions to feed 3D food printers. The research will investigate the performance of gelation and stabilisation options and test the quality of outcomes using 3D-food printers. Research will use a texture analyser, headspace GC-MS aroma measurement and electronic togue to characterise the outcomes of formulation and processing variables required for stabilization and successful 3D printing into consumer desirable food formats. Graduates from this research will be skilled in the creation of new food products for a career in advanced food product development.
