This project is an emerging collaboration between the University of Melbourne, Food Science Australia and the Dairy Ingredients Group of Australia. We aim to use acoustically generated chemical and physical effects to modify dairy proteins. Transformation of the sulphur-containing proteins by this means should overcome many of the difficulties currently encountered in thermal processing of whole milk and whey proteins. This work will place the Australian dairy industry in a pre-eminent position for the development of valuable, heat-stable and uniquely functional ingredients based on novel micro/nano structures. Existing world class expertise will be further developed in ultrasonic processing and sonochemistry as frontier technologies.Read moreRead less
High-value functional ingredients from bean processing waste. Legumes are considered highly nutritious and sustainable food. Accordingly, there is a steady growth in the consumption of legumes worldwide, including in Australia. Due to lengthy soaking and cooking times, consumers prefer ready-to-eat canned legumes. The current processing technologies are energy and water-intensive and generate considerable waste. This project investigates the application of non-thermal technologies to reduce pro ....High-value functional ingredients from bean processing waste. Legumes are considered highly nutritious and sustainable food. Accordingly, there is a steady growth in the consumption of legumes worldwide, including in Australia. Due to lengthy soaking and cooking times, consumers prefer ready-to-eat canned legumes. The current processing technologies are energy and water-intensive and generate considerable waste. This project investigates the application of non-thermal technologies to reduce processing time, water and energy use and enable the recovery of valuable polyphenols and soluble dietary fibres normally lost in the wastewater. This knowledge will lead to sustainable beans processing, delivering improved productivity to Australian manufacturers and quality food to Australian consumers.Read moreRead less
Innovative zero-energy membrane technologies to reduce water consumption in the dairy industry. The Australian dairy industry not only plays a critical role in our way of life, but processed dairy products contribute to 12% or $3.27b to Australia's export revenue. It has learnt to adapt to changing market demands through innovative membrane technologies, but now energy and water are key issues. This project aims to reduce water consumption in dairy processing by treating waste streams using nove ....Innovative zero-energy membrane technologies to reduce water consumption in the dairy industry. The Australian dairy industry not only plays a critical role in our way of life, but processed dairy products contribute to 12% or $3.27b to Australia's export revenue. It has learnt to adapt to changing market demands through innovative membrane technologies, but now energy and water are key issues. This project aims to reduce water consumption in dairy processing by treating waste streams using novel membrane processes including membrane distillation. The energy is supplied from low grade waste heat, offsetting the need to supply more power to the plant. Reducing the need for water in a zero-energy way will ensure the thriving dairy industry remains cost competitive and an integral part of Australia's culture and economy.Read moreRead less

The innovation gained is also applicable to food and pharmaceutical industries where spray drying and fluidised bed drying are integral parts of the manufacturing process. The project will train graduates to be able to make a high-level contribution to these industries.Read moreRead less
Tomato and vegetable oil synergies for healthier foods. Vegetable and fruit products are recognised for their content of health-promoting phytonutrients. This project will investigate the bioavailability and subsequent in-vivo antioxidant activity of tomatoes and vegetable oils alone or in combination. A second aim will be to isolate particular phytonutrients from tomates and selected vegetable oils, and then to combine them for determination of synergistic interactions affecting antioxidant ac ....Tomato and vegetable oil synergies for healthier foods. Vegetable and fruit products are recognised for their content of health-promoting phytonutrients. This project will investigate the bioavailability and subsequent in-vivo antioxidant activity of tomatoes and vegetable oils alone or in combination. A second aim will be to isolate particular phytonutrients from tomates and selected vegetable oils, and then to combine them for determination of synergistic interactions affecting antioxidant activity. Opportunities for the preparation of new phytonutrient-oil combination foods with increased antioxidant activity and the potential to enhance the health status of consumers will be developed. The research will provide food processors with expertise to develop novel plant-derived ingredients and food products for sale in the internationally growing functional foods market.Read moreRead less
Incorporation of legume protein in liquid breakfast for a healthy Australia. This project aims to understand and control the properties and interactions of legume protein with other ingredients (e.g. whey protein and dietary fibre) to formulate healthy liquid foods with superior techno-functionality. This research should significantly broaden our understanding of the behaviour of legume protein-phospholipid complexes and their contribution to malodorous flavour development. The expected outcomes ....Incorporation of legume protein in liquid breakfast for a healthy Australia. This project aims to understand and control the properties and interactions of legume protein with other ingredients (e.g. whey protein and dietary fibre) to formulate healthy liquid foods with superior techno-functionality. This research should significantly broaden our understanding of the behaviour of legume protein-phospholipid complexes and their contribution to malodorous flavour development. The expected outcomes are protocols to prevent undesirable sensory characteristics in liquid foods. This should benefit the food industry by improving the sensory attributes of beverages enriched with legume protein, leading to the creation of novel, highly nutritious products with superior sensory attributes and long shelf-life.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
