An important operation in the food industry is the physical separation of valuable particles from a mixture containing waste materials, such as shell fragments. The purpose of this study is to investigate the application of a novel gas-solid fluidised bed system, utilising parallel inclined plates to radically amplify the differential segregation rates to produce separations based on particle size. Our aim is to develop a fundamental understanding of the principles governing the nature of this system. The project should result in considerable technological and economic benefits for the food industry, a well trained and educated person at the postgraduate level, and a stronger collaborative link between the University and Sanitarium.Read moreRead less
A Novel Rheological and Chewing and Swallowing model for the Smart Design of Texture Modified Foods for Increased Aged Health. Difficulty in chewing and swallowing mean about 40% of elderly people require Texture Modified (TM) meals. Elders able to eat only very soft food textures have a 2.4 fold higher risk of mortality. However existing methods to assess the level of texture modification are poor; achieving a consistent level of TM meal is difficult; and TM meals have poor sensory properties ( ....A Novel Rheological and Chewing and Swallowing model for the Smart Design of Texture Modified Foods for Increased Aged Health. Difficulty in chewing and swallowing mean about 40% of elderly people require Texture Modified (TM) meals. Elders able to eat only very soft food textures have a 2.4 fold higher risk of mortality. However existing methods to assess the level of texture modification are poor; achieving a consistent level of TM meal is difficult; and TM meals have poor sensory properties (appearance, flavour, aroma). This work will use a novel chewing and swallowing model in conjunction with novel food flavour and property measurements to develop new texture modified foods with increased taste, ease of swallowing and nutritional value.Read moreRead less

New Optimisation and Control Technologies for Milk Powder Manufacturing Processes. Advanced optimisation and control are considered to be one of the top technologies that help milk powder producers operate their plants more efficiently. However, the successful implementations of these technologies are limited due to poor understanding of the relationship between raw material variations and process disturbances with the target variables. Moreover, uncertainties in process measurements also preven ....New Optimisation and Control Technologies for Milk Powder Manufacturing Processes. Advanced optimisation and control are considered to be one of the top technologies that help milk powder producers operate their plants more efficiently. However, the successful implementations of these technologies are limited due to poor understanding of the relationship between raw material variations and process disturbances with the target variables. Moreover, uncertainties in process measurements also prevent reliable control and effective optimisation. This project aims to address these gaps by developing new optimisation and control methods based on effective model reduction and uncertainty process variable identification, to enable Australian milk powder manufacturers to continuously improve productivity and reduce cost.Read moreRead less

This project links together two diverse but important areas of national importance: declining fisheries and human health. Australia is a small producer and exporter of fish but has access to significant fisheries. The Geelong Food Co-product Cluster comprises a number of fish companies facing serious problems associated with declining catches compounded by the current financial crisis. Increasing use of by-catch species and developing novel processing technology for controlled release of bioactive peptides that may reduce appetite and the tendency for overweight and obesity in consumers could provide the Australian seafood industry with a world competitive innovative technology leading to improvements in human health.Read moreRead less

These outcomes have enormous implications for human health and disease, and for the sugar industry, thus providing a competitive edge in the world sugar market.Read moreRead less
Development and evaulation of novel foods enriched with very long chain omega-3 fatty acids. This project is a collaborative effort between Meadow Lea Foods, Clover Corporation, and the Universities of Wollongong and Western Australia. The aims are 1) to develop a range of functional foods enriched with omega-3 from tuna oil; 2) to see whether the recommended omega-3 intake, currently nor met by most Australians, can be achieved by including these foods in the diet; 3) to evaluate sensory and he ....Development and evaulation of novel foods enriched with very long chain omega-3 fatty acids. This project is a collaborative effort between Meadow Lea Foods, Clover Corporation, and the Universities of Wollongong and Western Australia. The aims are 1) to develop a range of functional foods enriched with omega-3 from tuna oil; 2) to see whether the recommended omega-3 intake, currently nor met by most Australians, can be achieved by including these foods in the diet; 3) to evaluate sensory and health attributes and other factors that may impact on consumer acceptability hence market potential of the food range. There is little evidence of the feasibility let alone health and social benefits of utilising novel foods to meet the dietary omega-3 recommendation. We expect a) to show how consumers could benefit by using a range of such foods in their customary diet; b) to critically set this achievement within the context of current social trends in food product development.
