The role of fat crystal wettability in altering dairy emulsion properties. This project aims to control fat crystal wettability, to create tailored dairy products with desirable stability, shelf-life and texture. Fat crystals are an essential component of dairy emulsions (fat droplets dispersed in dairy/milk serum) and control product processing, shelf life and texture. Their structuring role involves partial coalescence: the formation of complicated network structures of fat droplets. Unless fat crystals are partially wetted by water, they will not be present at the fat droplet interface, and partial coalescence will not occur. Expected outcomes are new dairy products with optimum stability and texture.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

Development and application of an index for substantiating health benefits of omega-3 enriched foods. A cost-effective means of substantiating health claims for omega-3 (w3) rich functional foods is needed to fully exploit growing consumer demand for these products. In a two-stage approach, cardiovascular and anti-inflammatory benefits of w3 will be assessed in human dietary trials; improvements of health status in response to graded doses of w3 supplements will be correlated with docosahexaenoi ....Development and application of an index for substantiating health benefits of omega-3 enriched foods. A cost-effective means of substantiating health claims for omega-3 (w3) rich functional foods is needed to fully exploit growing consumer demand for these products. In a two-stage approach, cardiovascular and anti-inflammatory benefits of w3 will be assessed in human dietary trials; improvements of health status in response to graded doses of w3 supplements will be correlated with docosahexaenoic acid (DHA) levels in erythrocytes (DHA Index). Simple bioavailability trials can then be used to determine the intakes of foods required to attain the DHA Index, thus confirming their potential to deliver specified health benefits. Initial trials will support health claims for w3 rich fresh pork and processed pork products.Read moreRead less
Development of Multilayered Packaging Materials with Controlled Barrier Properties.

The project aims to develop advanced new material for multilayered packaging with high oxygen and moisture barrier properties for cost effective packaging applications. Poly Products currently imports and uses some polymer as its key component for controlling barrier property of their food packaging. However, the new nanostructured material when sandwiched between less expensive materials in a multilayered packaging film will yield excellent barrier properties, leading to extended shelf life of different food products. The new smart material will generate significant material saving and replace the imported polymer, and will secure export market of the product in Asia -Pacific region.Read moreRead less

The project aims to determine the role root microbes play in controlling seagrass responses to environmental stress. By integrating marine and microbial ecology, environmental genomics and ecosystem function (e.g., biogeochemical cycling), this project is significant as it will create new knowledge of the processes that confer seagrass resilience to global environmental issues. An expected outcome is an increased understanding of how microbes control seagrass health and an enhanced capacity to develop effective restoration strategies for Australia's valuable seagrass ecosystems. Benefits include improving the extensive environmental, economic, social/cultural services Australian communities derive from seagrass ecosystems.Read moreRead less

Three-dimensional structures, substrate specificities and catalytic mechanisms of polysaccharide synthases. Plant wall polysaccharides are extensively used for food and fibre, and are important dietary components in human nutrition. A precise knowledge of mechanisms used by plants to synthesize these polysaccharides is unavailable, but would reveal potential routes to manipulate their biosynthesis in important crop species.

Plant wall polysaccharides are extensively used for food and fibre, and are important dietary components in human nutrition. A precise knowledge of mechanisms used by plants to synthesize these polysaccharides is unavailable, but would reveal potential routes to manipulate their biosynthesis in important crop species. For example, the levels or structures of polysaccharides might be modified to improve their efficacy as anti-cancer agents in human diets, to enhance digestibility of animal stock feeds, or to synthesise pharmologically valuable compounds. Thus, economic, social and environmental benefits will flow to both producers and consumers. Read moreRead less

The multibillion-dollar wine industry forms a significant part of the Australian economy especially in regional areas. The application of high power ultrasound (HPU) to the cleaning and disinfection of wine barrels as well as for the enhancement of wine through improved fermentation and extraction of flavours and colours from grapes will have significant benefits to this industry. It is essential that Australia also capitalise on the benefits that this technology can provide in improved processing and products, lower costs, reduction in environmental pollution, water re-use and replacement of "dirty" energy. In this way the impact on this industry will help cement Australia's position in the world wine market long into the future.Read moreRead less
