This project aims to develop a technological platform for the fabrication of flexible sensors that enable the detection of food spoilage and life threatening microbial contamination. By engineering stimuli-responsive inks, colorimetric, chemiresistive, and impedimetric sensor arrays will be printed on flexible plastics and paper substrates. The printed sensor arrays will respond to gases and volatile compounds generated from food deterioration and spoilage, microbial pathogen, temperature and pH by a change in their colour or electrical properties, hence providing real-time measurements. The project will enable to design efficient data-driven decision making tools along the supply chain to enhance food safety and reduce food waste. Read moreRead less
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

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.

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
The Molecular Mechanism of Protein Instability in Dairy Powder Systems. Dairy is the fourth largest rural industry sectors in Australia, directly involving more than 13,000 farms and a large number of dairy factories. Most of Australia's 10 billion litre milk flow is converted to powder form for exports, with an annual value exceeding $1billion. The anticipated improvements in the performance and shelf-life of the dried dairy powder systems to be investigated in this project have the potential ....The Molecular Mechanism of Protein Instability in Dairy Powder Systems. Dairy is the fourth largest rural industry sectors in Australia, directly involving more than 13,000 farms and a large number of dairy factories. Most of Australia's 10 billion litre milk flow is converted to powder form for exports, with an annual value exceeding $1billion. The anticipated improvements in the performance and shelf-life of the dried dairy powder systems to be investigated in this project have the potential to generate significant economic impacts in both the dairy production and processing sectors. This work will also benefit the wider scientific community in dairy- and food-related areas, particularly in relation to the novel multidisciplinary approach involving a combination of material science and protein chemistry.Read moreRead less

Creation of a new branch of food research by utilising whey protein in the development of novel products of low calorie content and glycemic response. Australian consumers are demanding healthy foods, yet our society is suffering from 'diseases of choice' such as obesity that largely result from our lifestyle. One particular problem is the low intake of nutrients in contemporary diet. Growing consumer interest in readily available and affordable foods with good nutrition has focused the industry ....Creation of a new branch of food research by utilising whey protein in the development of novel products of low calorie content and glycemic response. Australian consumers are demanding healthy foods, yet our society is suffering from 'diseases of choice' such as obesity that largely result from our lifestyle. One particular problem is the low intake of nutrients in contemporary diet. Growing consumer interest in readily available and affordable foods with good nutrition has focused the industry on the merits of whey protein in processed products. This project will address the issue of consumer acceptability of whey-protein based products by rationalising at the molecular level the interactions of the protein with soluble dietary fibre and starch leading to added value formulations of appealing texture, low-calorie content and low glycemic load.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
