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
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
Addressing Child Nutritional Deficiency Through Development of a Nutritious Food Based on Dried Vegetable or Fruit. A significant proportion of Australian children are deficient in nutrients that dramatically affect mental and physical development. To improve health and wellness, micronutrients must be in a palatable form and be sufficiently absorbed to improve nutritional status. To optimise stability during processing, sensory quality and metabolic absorption, appropriate micronutrient food fo ....Addressing Child Nutritional Deficiency Through Development of a Nutritious Food Based on Dried Vegetable or Fruit. A significant proportion of Australian children are deficient in nutrients that dramatically affect mental and physical development. To improve health and wellness, micronutrients must be in a palatable form and be sufficiently absorbed to improve nutritional status. To optimise stability during processing, sensory quality and metabolic absorption, appropriate micronutrient food fortification technology must be used. This project proposes a unique linkage between three distinct University faculties and Industry, to combine the development of novel fortified dried-vegetable and/or fruit leathers with an efficient process for their production, nutritional studies to assess their absorption, and target market (young children) acceptance studies.Read moreRead less
Evaluation of High-Power Ultrasound as an Innovative Tool for Sanitation, Colour/Flavour Extraction and Fermentation Enhancement in Wine Making. The multibillion-dollar wine industry forms a significant part of the Australian economy especially in regional areas.

The multibillion-dollar wine industry forms a significant part of the Australian economy especially in regional areas. The application of high power ultrasound (HPU) to the cleaning and disinfection of wine barrels as well as for the enhancement of wine through improved fermentation and extraction of flavours and colours from grapes will have significant benefits to this industry. It is essential that Australia also capitalise on the benefits that this technology can provide in improved processing and products, lower costs, reduction in environmental pollution, water re-use and replacement of "dirty" energy. In this way the impact on this industry will help cement Australia's position in the world wine market long into the future.Read moreRead less

Microstructure and Rheology of Starch-Gelatine confectionery products as a function of manufacturing process. We propose to develop a novel continuous extrusion process for manufacturing confectionery jellies. Jellies are traditionally manufactured in a multi-step labour and capital-intensive batch process with inter-batch variability and difficult to automate.

We propose to develop a novel continuous extrusion process for manufacturing confectionery jellies. Jellies are traditionally manufactured in a multi-step labour and capital-intensive batch process with inter-batch variability and difficult to automate. Continuous processes offer many advantages including high throughput, efficiency, straightforward automation including quality monitoring and control. They are little used in this industry because of the inability to relate product requirements through fundamental microstructural properties to processing conditions. This project addresses these key technical obstacles to gain the competitive advantage of continuous extrusion processing, through advanced mathematical modelling informed by experimentation. The proposed techniques derive from advanced polymer processing and characterisation capabilities.Read moreRead less
Development of bagasse fly ash adsorbent for the removal of impurities in sugar process streams. High quality raw sugar attracts a premium and is important in maintaining market access in these times of increasing competition and excess production from overseas producers. Options that are in current use in Australia for the removal of colour and impurities are not very cost effective. This research will develop a sugarcane waste (fly ash) into an adsorbent for the removal of these impurities.

High quality raw sugar attracts a premium and is important in maintaining market access in these times of increasing competition and excess production from overseas producers. Options that are in current use in Australia for the removal of colour and impurities are not very cost effective. This research will develop a sugarcane waste (fly ash) into an adsorbent for the removal of these impurities. This will enable the sugar industry and rural communities to become more sustainable through enhanced competitiveness and diversification through co-generation and value-added products. This project will also reduce the disposal costs ($2 M/y) for the sugar industry and minimize environmental pollution due to the use of a waste product.Read moreRead less
