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

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 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

This project aims to design the most comprehensive specifications yet for nutritionally enhanced and health-modulating starch in grain-based foods. Why starch resists small intestinal digestion is not understood; this limits plant breeders and food (ingredient) manufacturers’ ability to tailor starch structures for optimal human nutritional value. This project will study how resistant starch survives digestion in the small intestine and passed to the large intestine using a model for the large intestine to define the microbial fermentation of resistant starch fractions. This research is expected to improve breeding programmes and food ingredients and promote the nutritional value of grain-based foods.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

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

The outcomes of this project will lead to the establishment of a new paradigm in designing foods, beverages and oral care products that have tailored health and vitality benefits (e.g. reduced levels of fat, sugar and salt). In addition, these foods will contain beneficial additives (e.g. anti-oxidants, vitamins, minerals, phytonutrients) targeted to specific consumer groups according to their lifestyle, age, medical condition or requirement for nutritional/nourishment efficacy, thereby contributing to healthy ageing. It is foreseen that this novel approach to designing foods will be extended to products intended for consumers whose sensory perception is compromised by existing medical therapeutic practices (such as radiation therapy).Read moreRead less
