Nanostructured dairy powder for improved functionality. More than 30 per cent of the total milk produced in Australia is converted to powder for export. This project will lead to improvement in the solubility, and hence shelf-life, of protein rich dairy powders which will be of significant economic benefit to the industry. This project will also benefit the wider scientific community in dairy and food sectors.
A Novel Rheological and Chewing and Swallowing model for the Smart Design of Texture Modified Foods for Increased Aged Health. Difficulty in chewing and swallowing mean about 40% of elderly people require Texture Modified (TM) meals. Elders able to eat only very soft food textures have a 2.4 fold higher risk of mortality. However existing methods to assess the level of texture modification are poor; achieving a consistent level of TM meal is difficult; and TM meals have poor sensory properties ( ....A Novel Rheological and Chewing and Swallowing model for the Smart Design of Texture Modified Foods for Increased Aged Health. Difficulty in chewing and swallowing mean about 40% of elderly people require Texture Modified (TM) meals. Elders able to eat only very soft food textures have a 2.4 fold higher risk of mortality. However existing methods to assess the level of texture modification are poor; achieving a consistent level of TM meal is difficult; and TM meals have poor sensory properties (appearance, flavour, aroma). This work will use a novel chewing and swallowing model in conjunction with novel food flavour and property measurements to develop new texture modified foods with increased taste, ease of swallowing and nutritional value.Read moreRead less
Markers of milk quality in commercially produced UHT milks and milk powders. Efficient production of safe, wholesome food relies on the application of the best available knowledge of the food material and the processing technologies involved. This project applies proteomics, the most advanced protein analysis technique, to determine the changes that occur in milk during high heat treatment and subsequent storage of the heat-processed milk product. Armed with such knowledge, the dairy processin ....Markers of milk quality in commercially produced UHT milks and milk powders. Efficient production of safe, wholesome food relies on the application of the best available knowledge of the food material and the processing technologies involved. This project applies proteomics, the most advanced protein analysis technique, to determine the changes that occur in milk during high heat treatment and subsequent storage of the heat-processed milk product. Armed with such knowledge, the dairy processing industry will be able to make informed decisions about processing and storage conditions to ensure the final products provided to the consumer are of the highest possible quality.

High-value functional ingredients from bean processing waste. Legumes are considered highly nutritious and sustainable food. Accordingly, there is a steady growth in the consumption of legumes worldwide, including in Australia. Due to lengthy soaking and cooking times, consumers prefer ready-to-eat canned legumes. The current processing technologies are energy and water-intensive and generate considerable waste. This project investigates the application of non-thermal technologies to reduce pro ....High-value functional ingredients from bean processing waste. Legumes are considered highly nutritious and sustainable food. Accordingly, there is a steady growth in the consumption of legumes worldwide, including in Australia. Due to lengthy soaking and cooking times, consumers prefer ready-to-eat canned legumes. The current processing technologies are energy and water-intensive and generate considerable waste. This project investigates the application of non-thermal technologies to reduce processing time, water and energy use and enable the recovery of valuable polyphenols and soluble dietary fibres normally lost in the wastewater. This knowledge will lead to sustainable beans processing, delivering improved productivity to Australian manufacturers and quality food to Australian consumers.Read moreRead less
Ultrasonic Processing of Dairy Ingredients to Control Protein Aggregation and Promote Heat Stability. This project is an emerging collaboration between the University of Melbourne, Food Science Australia and the Dairy Ingredients Group of Australia. We aim to use acoustically generated chemical and physical effects to modify dairy proteins.

This project is an emerging collaboration between the University of Melbourne, Food Science Australia and the Dairy Ingredients Group of Australia. We aim to use acoustically generated chemical and physical effects to modify dairy proteins. Transformation of the sulphur-containing proteins by this means should overcome many of the difficulties currently encountered in thermal processing of whole milk and whey proteins. This work will place the Australian dairy industry in a pre-eminent position for the development of valuable, heat-stable and uniquely functional ingredients based on novel micro/nano structures. Existing world class expertise will be further developed in ultrasonic processing and sonochemistry as frontier technologies.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
