Establishing the relations between starch nano- and mesostructure and macroscopic physical properties. Starch is the major energy component within human diets, and the most abundant polymer that can be readily extracted from annual crop plants, leading to many actual and potential industrial applications.

Starch is the major energy component within human diets, and the most abundant polymer that can be readily extracted from annual crop plants, leading to many actual and potential industrial applications. There are major opportunities to optimise the nutritional value of starches in the human diet, and to enhance the properties of extracted starches as renewable alternatives to petrochemical polymers. This project will open up our understanding of the structure of starch polymers and show how this relates to important properties such as enzyme digestibility rates, leading to new opportunities for public health and commercial benefits.Read moreRead less
Controlled Crystallisation of Bioactives. The new technologies developed in this project for bioactive recovery and particle design will allow the development of new value added products for Australia's growing biotechnology industry, especially in pharmaceuticals, neutraceuticals and functional foods. Two PhD students will receive excellent research training to then move into research and development in these industries.
Particle Design for Recovery and Delivery of Bioactives. This project will develop new strategies for economically viable recovery of bioactives from complex solutions, slurries and sludges of biomaterials eg. waste streams from milk and soy bean processing, and fermentation broths. These bioactives, often proteins, have growing applications as high value drugs, nutriceuticals and food additives but are difficult to separate and to maintain in an active form. Crystallisation will be used as a ....Particle Design for Recovery and Delivery of Bioactives. This project will develop new strategies for economically viable recovery of bioactives from complex solutions, slurries and sludges of biomaterials eg. waste streams from milk and soy bean processing, and fermentation broths. These bioactives, often proteins, have growing applications as high value drugs, nutriceuticals and food additives but are difficult to separate and to maintain in an active form. Crystallisation will be used as a primary separation technique. Molecular studies of protein interactions will be used to predict good crystallisation conditions and linked to process crystallisation studies. Both standard and novel particle design strategies will be used to control crystal size and morphology, as well as package the boactive in a deliverable form without loss of activity.Read moreRead less
Particle design and recovery of bioactives by crystallisation and precipitation. This project will develop new strategies for economically viable recovery of bioactives from complex solutions of biomaterials eg. separation of biopharmaceuticals from genetically engineered cell culture, food ingredient processing, functional food and nutraceutical extraction from natural sources. Crystallisation and precipitation will be used as primary separation techniques. We propose a new paradigm in which ....Particle design and recovery of bioactives by crystallisation and precipitation. This project will develop new strategies for economically viable recovery of bioactives from complex solutions of biomaterials eg. separation of biopharmaceuticals from genetically engineered cell culture, food ingredient processing, functional food and nutraceutical extraction from natural sources. Crystallisation and precipitation will be used as primary separation techniques. We propose a new paradigm in which molecular studies of protein interactions will be used to predict good crystallisation conditions and linked to process crystalliation studies. Studies will use a model system of egg white protein mixtures and a real system of industrial importance - the purification of valuable protein products from soy beans (valued at $500 million per year world wide). Soy beans studies will include pilot scale tests at Dupont's industrial reseach laboratories.Read moreRead less

The flotation of oxide minerals using hydroxamate collectors. Australian and world mineral resources are declining in quality as we exploit the richest sulfidic ore deposits. This is increasing our reliance on concentration and beneficiation processes to improve the economics of the selective recovery of minerals from lower grade and, increasingly, oxide or lateritic ore bodies. In addition, greater emphasis is being placed on our environmental stewardship and the need to remove hazardous mater ....The flotation of oxide minerals using hydroxamate collectors. Australian and world mineral resources are declining in quality as we exploit the richest sulfidic ore deposits. This is increasing our reliance on concentration and beneficiation processes to improve the economics of the selective recovery of minerals from lower grade and, increasingly, oxide or lateritic ore bodies. In addition, greater emphasis is being placed on our environmental stewardship and the need to remove hazardous material from the concentrate streams. This proposal will develop improved methods and techniques that will facilitate better, cleaner separations and recovery of the valuable oxide mineral components using Australian-developed flotation reagents.Read moreRead less
