Understanding of structure development in drying droplets through the stickiness paradigm. The aims of this research are to develop a new model for multicomponent droplet drying. This model will provide predictions of conditions where composition variation exists in the drying particles. Validation of the model will be made using a novel instrument to measure the in-situ development of surface stickiness during drying. Stickiness is an important issue encountered during drying and handling of so ....Understanding of structure development in drying droplets through the stickiness paradigm. The aims of this research are to develop a new model for multicomponent droplet drying. This model will provide predictions of conditions where composition variation exists in the drying particles. Validation of the model will be made using a novel instrument to measure the in-situ development of surface stickiness during drying. Stickiness is an important issue encountered during drying and handling of some key food and consumer materials. Currently, there is no technique to measure the evolution of stickiness during drying. Key outputs will include the model, the instrument, and the development of efficient methods to generate the multicomponent data.Read moreRead less
Surface Modification of Spray-Dried Powders By Surface-Active Proteins. Internal wall deposits in spray dryers lead to product degradation and pose fire hazards. This situation has limited the manufacturing of high value bio-food powders by the Australian bio-food and dairy industry, which exports 13% of the milk powder in the world. The specific economic benefits to Australia from this project arise from innovative surface modification of powder particles by proteins, development of scientific ....Surface Modification of Spray-Dried Powders By Surface-Active Proteins. Internal wall deposits in spray dryers lead to product degradation and pose fire hazards. This situation has limited the manufacturing of high value bio-food powders by the Australian bio-food and dairy industry, which exports 13% of the milk powder in the world. The specific economic benefits to Australia from this project arise from innovative surface modification of powder particles by proteins, development of scientific instruments and predictive tools based on Computational Fluid Dynamics (CFD). These outcomes will lead to production of free flowing powders from bio-food materials.Read moreRead less
Self-assembly of gelling biopolymer particles. Biopolymers provide a renewable source of structuring agents for a variety of potential uses in food, pharmaceutical and other applications that require bio-compatibility. Swollen biopolymer particles of sub-millimetre size are particularly useful as they combine macroscopic structure formation with an ability to flow and a desirable soft solid texture. Two limitations to the current utilisation of biopolymer particles are that they either cannot be ....Self-assembly of gelling biopolymer particles. Biopolymers provide a renewable source of structuring agents for a variety of potential uses in food, pharmaceutical and other applications that require bio-compatibility. Swollen biopolymer particles of sub-millimetre size are particularly useful as they combine macroscopic structure formation with an ability to flow and a desirable soft solid texture. Two limitations to the current utilisation of biopolymer particles are that they either cannot be predictably produced direct from a dried form, or if they are (e.g. cooked starch granules), there is a lack of scientific understanding that limits use of natural sources without subsequent chemical modification. This project will provide the science & technology to overcome these limitations.Read moreRead less
A Concurrent Multiscale Model for Improved Prediction of Drying Process. This project aims to develop an innovative multiscale model for food drying, which integrates spatial and temporal nonlinear behaviours at different scales. The proposed unifying theory will capture dynamic micro level features and upscale them to macro level features through a concurrent bridging scheme. As cellular elements critically govern the drying process, the fundamental understanding captured through this theory wi ....A Concurrent Multiscale Model for Improved Prediction of Drying Process. This project aims to develop an innovative multiscale model for food drying, which integrates spatial and temporal nonlinear behaviours at different scales. The proposed unifying theory will capture dynamic micro level features and upscale them to macro level features through a concurrent bridging scheme. As cellular elements critically govern the drying process, the fundamental understanding captured through this theory will lead to more accurate prediction of drying kinetics, deformation and quality changes, and hence the development of efficient drying systems. This project will overcome a longstanding research problem and position Australia at the forefront in world drying research to reap substantial economic benefits for Australia.Read moreRead less
Structural understanding of the degradation of glucose polymers. Understanding starch and glycogen breakdown at the molecular level is important for human nutrition and health. The understanding from this project will lead to new means for the control and mitigation of nutritional diseases, such as diabetes and obesity, as well as improved foods.
Honesty and efficiency in the provision of expert services: doctors and other experts as participants in economic experiments. Experts serve us when we see the doctor, the financial planner or the car mechanic. In all these case the expert can take advantage of his superior knowledge and sell us something we do not need. This research will inform policy makers about the underlying motives of real world experts and allow them to design better institutions.
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. 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 pol ....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. 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
Games and decisions with bounded rationality: theory and economic implications. This project will develop concepts and tools for decision making in complex environments, where it is impossible to fully characterise the possible outcomes and factors that may affect them. A central goal will be to integrate heuristic rules such as the precautionary principle with the more formal approach adopted in benefit-cost analysis.
Genetic Basis of Variable Expression of Glycan Xeno-Autoantigens by Cattle. Meat and dairy products from cattle contain sugar structures (glycans) that are not made by humans. These structures can be recognised by the immune system and lead to allergic reactions, inflammation and potentially cancer. These non-human structures are called xeno-autoantigens or XAs. We have discovered individual cattle that do not produce one of these XAs. We will study the gene required to make XA in the XA-free ca ....Genetic Basis of Variable Expression of Glycan Xeno-Autoantigens by Cattle. Meat and dairy products from cattle contain sugar structures (glycans) that are not made by humans. These structures can be recognised by the immune system and lead to allergic reactions, inflammation and potentially cancer. These non-human structures are called xeno-autoantigens or XAs. We have discovered individual cattle that do not produce one of these XAs. We will study the gene required to make XA in the XA-free cattle to find the underlying mutation. The same approach will be used to look for natural XA-free individuals in other food species. This knowledge may enable us to create a test to facilitate the natural breeding of non-GMO, XA-free livestock to benefit Australian primary producers and provide safer food for consumers.Read moreRead less
How eating patterns interact with activity, sleep and mood. This project aims to understand temporal eating patterns (the timing and distribution of food intake and eating occasions across the day) among adults and how these eating patterns interact with activity and sleep patterns. Eating, activity and sleep patterns form a lifestyle triad which may be important for well-being and productivity. The project will study eating, activity and sleep patterns in daily life, to examine their social dri ....How eating patterns interact with activity, sleep and mood. This project aims to understand temporal eating patterns (the timing and distribution of food intake and eating occasions across the day) among adults and how these eating patterns interact with activity and sleep patterns. Eating, activity and sleep patterns form a lifestyle triad which may be important for well-being and productivity. The project will study eating, activity and sleep patterns in daily life, to examine their social drivers, interactions and effect on mood. This project could enable these behaviours to be targeted, with the potential to promote healthy lifestyles and improve health, quality of life and productivity.Read moreRead less
