Omega-3 fatty acids, appetite and growth in farmed fish. Australia has very limited wild fish supplies, and with the increasing realization of human health benefits of fish (i.e. omega-3 fatty acid) there is a need to increase availability through aquaculture. However, feeds used in aquaculture contain costly fish oil with limited global supplies. Attempts made to substitute fish oil with vegetable sources in aquaculture feeds have been mixed. This international, comparative and multidisciplinar ....Omega-3 fatty acids, appetite and growth in farmed fish. Australia has very limited wild fish supplies, and with the increasing realization of human health benefits of fish (i.e. omega-3 fatty acid) there is a need to increase availability through aquaculture. However, feeds used in aquaculture contain costly fish oil with limited global supplies. Attempts made to substitute fish oil with vegetable sources in aquaculture feeds have been mixed. This international, comparative and multidisciplinary project aims to reduce the dependence on fish oils through investigation of basic fatty acid metabolism and endocrinology on farmed fish to ensure that human health promoting characteristics in the final product are retained.Read moreRead less
Salt (sodium) is an essential electrolyte. Our convincing and complementary findings provide compelling evidence for a link between evolutionarily ancient “instincts” and substance abuse. This proposal is translational, including studies in opiate dependent humans. Our studies will establish how and where in the brain endogenous opioids are implicated in the gratification of salt appetite, how salt appetite is altered in opiate dependency and if salt appetite recovers following opiate withdrawal
Salt And Cardiovascular Disease: Does Acute Salt-Sensitivity Convey Greater Cardiovascular Risk?

Summary
Salt intake of Australian adults is 10X more than required. Further, salt intake in very young children is alarmingly high secondary to high consumption of salty snacks and processed food. High dietary salt intake has been associated with increased cardiovascular disease and death. We will examine the cardiovascular risks for adults and children on a high salt diet and examine whether switching to a low salt diet ameliorates the high blood pressure and heart disease caused by high salt diets

Milk mimicry: Self-assembly in complex lipid mixtures during digestion. This project aims to decipher the chemical complexity required to mimic the digestive behaviour of milk fats and to identify their influence on lipophilic nutrient activity during transit through the gut. The link between milk's complex fat composition and its nutrient delivery properties are unknown because the digestive colloidal structures that drive fat-soluble nutrient absorption are poorly understood. The project expec ....Milk mimicry: Self-assembly in complex lipid mixtures during digestion. This project aims to decipher the chemical complexity required to mimic the digestive behaviour of milk fats and to identify their influence on lipophilic nutrient activity during transit through the gut. The link between milk's complex fat composition and its nutrient delivery properties are unknown because the digestive colloidal structures that drive fat-soluble nutrient absorption are poorly understood. The project expects to identify which milk lipids are essential to milk’s role as nature’s nutrient delivery vehicle. It will also identify a universally-available nutrient delivery platform for resource-poor communities, and enhanced knowledge of lipid physical chemistry. The findings will promote greater interaction between the dairy and pharmaceutical industries, adding value to their respective products.Read moreRead less
Novel enzymatic processing methods and stabilization technologies for omega-3 oils. New and existing lipases will be applied to the concentration of omega-3 lipids from fish and algal oils. The primary aim of this project is to replace current chemical processes and high temperature distillation with milder enzymatic methods, providing high quality omega-3 concentrates for food and pharmaceutical purposes. The project aims to develop new immobilisation technology to enable multiple re-use of lip ....Novel enzymatic processing methods and stabilization technologies for omega-3 oils. New and existing lipases will be applied to the concentration of omega-3 lipids from fish and algal oils. The primary aim of this project is to replace current chemical processes and high temperature distillation with milder enzymatic methods, providing high quality omega-3 concentrates for food and pharmaceutical purposes. The project aims to develop new immobilisation technology to enable multiple re-use of lipases for the cost effective production of omega-3 concentrates and to apply new microencapsulation strategies to the stabilisation of omega-3 concentrates, enabling the delivery of omega-3s and other bioactive ingredients to a range of food and beverage products.Read moreRead less
New hyphenated chromatographic and spectroscopic methods for oil analysis. This project aims to use novel chemical separation methods combined with spectroscopy to identify useful markers in olive oil and essential oil to ensure purity, quality and authenticity, which are all ongoing issues in these industries in Australia and overseas. The project plans to compare and integrate results of multidimensional gas chromatography combined with mass spectrometry and Fourier transform infrared analyses ....New hyphenated chromatographic and spectroscopic methods for oil analysis. This project aims to use novel chemical separation methods combined with spectroscopy to identify useful markers in olive oil and essential oil to ensure purity, quality and authenticity, which are all ongoing issues in these industries in Australia and overseas. The project plans to compare and integrate results of multidimensional gas chromatography combined with mass spectrometry and Fourier transform infrared analyses with data libraries to generate precise molecular identification. The outcome is expected to help monitor adulteration of oils and maintain the high quality standards of Australian produce.Read moreRead less
