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

Development of solvent extraction systems for improved sugar quality and yield. The recent collapse in the international sugar price and increased competition amongst producers have highlighted the vulnerability of Australian sugar mills and the regional communities reliant on sugar cane growing to variation in the price of this commodity. Hence, the development of new, more efficient means to produce raw sugar of high quality is of paramount importance to maintain Australia as a low cost produ ....Development of solvent extraction systems for improved sugar quality and yield. The recent collapse in the international sugar price and increased competition amongst producers have highlighted the vulnerability of Australian sugar mills and the regional communities reliant on sugar cane growing to variation in the price of this commodity. Hence, the development of new, more efficient means to produce raw sugar of high quality is of paramount importance to maintain Australia as a low cost producer. This project aims to investigate the use of unique solvent extraction methods to remove deleterious impurities from the raw cane juice in sugar mills with the consequent improvement in both sugar yield and quality.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
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

The project is a key component of a technical development program that has the potential to make a very large contribution to the processing of functional foods resulting in products of high value for nutritional use. The total national crop of cereals, pulses, oil seeds, fruit and vegetables is thirty million tonnes/year. Over three million tonnes/year of waste are produced, containing three million kilogrammes of bioactive compounds, valued at a minimum of $1,000/kg, giving an estimated potential value of $3 billion/year. If only 10% of this potential is captured, then the national benefit would be as high as A$300 million/year.Read moreRead less

The inclusion of probiotic (beneficial) bacteria in foods is linked to positive health benefits by suppressing harmful micro-organisms in the gastro-intestinal tract (GIT). Prebiotic ingredients stimulate the growth of these bacteria. Since dairy products containing both probiotic and prebiotic ingredients ("synbiotic") are gaining importance globally, new protective measures are needed to preserve the activity and viability of these ingredients. This project aims to develop a new micro-encapsulation system to encapsulate bacteria within foods for safe delivery to GIT, to encapsulate enzymes for accelerated cheese ripening, that will significantly enhance the development of a new generation of healthy foods.Read moreRead less
