Understanding and Controlling Wall Deposition in Spray Dryers via Experimental and Computational Fluid Dynamics (CFD) Studies. A key problem in operating spray dryers for producing milk powders and other consumer products, such as detergents, is the occurrence of internal wall deposits of powder, leading to thermal degradation of the products and potential fire hazards. However, no fundamental theory has been applied in spray dryers to allow this process to be controlled. The proposed project wi ....Understanding and Controlling Wall Deposition in Spray Dryers via Experimental and Computational Fluid Dynamics (CFD) Studies. A key problem in operating spray dryers for producing milk powders and other consumer products, such as detergents, is the occurrence of internal wall deposits of powder, leading to thermal degradation of the products and potential fire hazards. However, no fundamental theory has been applied in spray dryers to allow this process to be controlled. The proposed project will use state-of-the-art experimental and computational techniques to gain a fundamental understanding of this phenomenon and will develop a validated wall deposition model to predict when and to what extent this process occurs, to give higher throughputs and/or more efficient systems.Read moreRead less
Optimising Removal of Proteinaceous Foulants from Membranes. Removal of proteinacous foulants from membrane systems imposes both significant economic costs in terms of chemical usage as well as significant environmental costs in terms of water usage and production of effluents from the cleaning and rinsing waters. The outcome of this project should allow us to develop methods for the prediction and optimisation of membrane cleaning performance of relevance to major Australian industries includin ....Optimising Removal of Proteinaceous Foulants from Membranes. Removal of proteinacous foulants from membrane systems imposes both significant economic costs in terms of chemical usage as well as significant environmental costs in terms of water usage and production of effluents from the cleaning and rinsing waters. The outcome of this project should allow us to develop methods for the prediction and optimisation of membrane cleaning performance of relevance to major Australian industries including the dairy, food processing and water and waste water treatment industries.Read moreRead less
Improving Powder Properties by Using Spray Dryers to Process Amorphous Components of Solids into Crystalline Materials. Australia has a large food and dairy processing industry, capturing 13% of the world dairy export market, worth US$460 million annually. This proposal will build on Australia's strengths in dairy and food industries, particularly milk powder products. This project will enhance our competitive advantage in the production of dried foodstuffs by streamlining their production and ....Improving Powder Properties by Using Spray Dryers to Process Amorphous Components of Solids into Crystalline Materials.

This proposal will build on Australia's strengths in dairy and food industries, particularly milk powder products. This project will enhance our competitive advantage in the production of dried foodstuffs by streamlining their production and allowing tailored and new powder products to be created.Read moreRead less
Dairy Milk Phospholipids in the Prevention of Atherosclerosis. The present project is expected to provide novel information pertaining to the separation of phospholipid (PL) fractions from buttermilk. In addition, it will generate scientific/medical knowledge concerning the use of dietary PL preparations in the prevention of arterial atherosclerosis. Together, this innovative research will help support the commercial development of PL separation from buttermilk. It will also lay the ground-wo ....Dairy Milk Phospholipids in the Prevention of Atherosclerosis. The present project is expected to provide novel information pertaining to the separation of phospholipid (PL) fractions from buttermilk. In addition, it will generate scientific/medical knowledge concerning the use of dietary PL preparations in the prevention of arterial atherosclerosis. Together, this innovative research will help support the commercial development of PL separation from buttermilk. It will also lay the ground-work for additional studies into the therapeutic benefit of dietary PLs and the commercialization of milk PL as a nutraceutical or functional food. The present project thus has significant academic, commercial and therapeutic value of potential benefit to all Australians.Read moreRead less
Development of mature and intense flavours in low-fat cheeses using micro-encapsulated enzyme technology. Obesity related diseases are escalating in Australia. Consumers, although encouraged to favour low-fat alternatives in their diet to combat obesity, find low-fat alternatives unpalatable and continue to select full-fat alternatives. There is a need to provide consumers with a full-fat flavoured low-fat cheese. The aim of this project is to develop low-fat cheese products with flavours compar ....Development of mature and intense flavours in low-fat cheeses using micro-encapsulated enzyme technology. Obesity related diseases are escalating in Australia. Consumers, although encouraged to favour low-fat alternatives in their diet to combat obesity, find low-fat alternatives unpalatable and continue to select full-fat alternatives. There is a need to provide consumers with a full-fat flavoured low-fat cheese. The aim of this project is to develop low-fat cheese products with flavours comparable to fully ripened, mature, full-fat cheeses using microencapsulation technology. The outcome will be a rise in demand for low-fat cheese products that will reduce dietary fat intake while maintaining the positive nutritional benefits associated with cheese.Read moreRead less
Development of a new micro-encapsulation system using a novel falling-film technology for bio-encapsulation of synbiotic functional dairy products. The inclusion of probiotic (beneficial) bacteria in foods is linked to positive health benefits by suppressing harmful micro-organisms in the gastro-intestinal tract (GIT). Prebiotic ingredients stimulate the growth of these bacteria. Since dairy products containing both probiotic and prebiotic ingredients ("synbiotic") are gaining importance globa ....Development of a new micro-encapsulation system using a novel falling-film technology for bio-encapsulation of synbiotic functional dairy products. The inclusion of probiotic (beneficial) bacteria in foods is linked to positive health benefits by suppressing harmful micro-organisms in the gastro-intestinal tract (GIT). Prebiotic ingredients stimulate the growth of these bacteria. Since dairy products containing both probiotic and prebiotic ingredients ("synbiotic") are gaining importance globally, new protective measures are needed to preserve the activity and viability of these ingredients. This project aims to develop a new micro-encapsulation system to encapsulate bacteria within foods for safe delivery to GIT, to encapsulate enzymes for accelerated cheese ripening, that will significantly enhance the development of a new generation of healthy foods.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
