Applications of probiotics in yoghurt, soy yoghurt and Cheddar cheese. The main goal of this study is to develop probiotic yoghurt and Cheddar cheese using selected strains of probiotic bacteria and examine their survival and effects on proteolysis and sensory attributes of these products. Research aimed at enrichment of suitable probiotic adjunct starter in these products provides the potential to markedly improve both the health status and quality of products. Optimum conditions for survival o ....Applications of probiotics in yoghurt, soy yoghurt and Cheddar cheese. The main goal of this study is to develop probiotic yoghurt and Cheddar cheese using selected strains of probiotic bacteria and examine their survival and effects on proteolysis and sensory attributes of these products. Research aimed at enrichment of suitable probiotic adjunct starter in these products provides the potential to markedly improve both the health status and quality of products. Optimum conditions for survival of probiotic bacteria and processing conditions that guarantee high levels of probiotic bacteria for health benefits will be known. The results will provide critical information for improving survival of probiotic bacteria and quality of probiotic yoghurt, and Cheddar cheese.Read moreRead less
Stability of bioactive isoflavone aglycones and probiotic bacteria in soy based food during processing and storage. The aims of this study are to ascertain the optimum conditions for bioconversion of inactive isoflavone glucosides to bioactive isoflavone aglycones by bifidobacteria and assess the stability of bioactive aglycones during processing and storage. Studies have shown that dietary phytoestrogen an important role in prevention of cardiovascular disease, osteoporosis and breast and prost ....Stability of bioactive isoflavone aglycones and probiotic bacteria in soy based food during processing and storage. The aims of this study are to ascertain the optimum conditions for bioconversion of inactive isoflavone glucosides to bioactive isoflavone aglycones by bifidobacteria and assess the stability of bioactive aglycones during processing and storage. Studies have shown that dietary phytoestrogen an important role in prevention of cardiovascular disease, osteoporosis and breast and prostate cancer (Nagata et al., 1998). Optimum conditions for production of bioactive isoflavones and processing conditions that guarantee high levels of bioactive isoflavones for health benefits will be known. The results will provide critical information for creating market potential for a range of health based functional foods.Read moreRead less
The development of novel oligosaccharides from dairy lactose for improved infant nutrition. This project will develop new milk sugars to enhance nutrition for the 46 per cent of infants who receive formula. It will support rural and regional dairy communities and manufacturers increasing innovation, potentially generating six million dollars in new sales per annum, increasing returns to farmers and promoting regional employment and spending.
The microbiology and biotechnology of rum production. Rum is an alcoholic beverage produced by microbial fermentation of molasses waste from the sugar industry. The microbial species responsible for the process determine rum flavour and quality by production of specific aroma compounds. The rate and extent of fermentation determine process efficiency. Several yeast and bacterial species contribute to rum fermentation but this ecology is poorly defined. Through a combination of ecological stu ....The microbiology and biotechnology of rum production. Rum is an alcoholic beverage produced by microbial fermentation of molasses waste from the sugar industry. The microbial species responsible for the process determine rum flavour and quality by production of specific aroma compounds. The rate and extent of fermentation determine process efficiency. Several yeast and bacterial species contribute to rum fermentation but this ecology is poorly defined. Through a combination of ecological studies, controlled fermentations and distillation, chemical and sensory analyses, this project will determine the impact of particular microbial species on rum flavour and process efficiency. This information will be used by the industrial partner to enchance product quality and process efficiency.Read moreRead less
Miniaturised biosensors with high selectivity . This project aims to develop a technological platform for the fabrication of miniaturised and flexible sensors that enable the quantitative detection of important bioactive compounds such as fatty acids and biogenic amines. By utilising multi-enzymatic reactions in solid phase and engineering task-specific inks, chemiresistive sensors will be printed seamlessly as a whole. The sensors will respond to complex target biomolecules via a series of enzy ....Miniaturised biosensors with high selectivity . This project aims to develop a technological platform for the fabrication of miniaturised and flexible sensors that enable the quantitative detection of important bioactive compounds such as fatty acids and biogenic amines. By utilising multi-enzymatic reactions in solid phase and engineering task-specific inks, chemiresistive sensors will be printed seamlessly as a whole. The sensors will respond to complex target biomolecules via a series of enzymatic reactions through which the analyte will convert to much simpler, reactive and hence measurable molecules. This project will enable to design miniaturised sensors for point-of-care detection of biomolecules that cannot be yet evaluated by the end users.Read moreRead less
