An expanded ?health-claims? system will likely be enacted by Food Standards Australia New Zealand within two years. Horticultural industries are attracted to the promotional ?point of difference? this offers. Many health-promoting compounds are antioxidants, including polyphenols that are abundant in fruit such as grape and citrus. Antioxidants are also involved in the plant's defences against abiotic and biotic stress. Here, the WA Table Grape industry has committed funds for an APAI to study regulation of antioxidants in relation to nutritional and postharvest qualities. Effects of preconditioning with mild oxidative stresses will be assayed, postharvest, using molecular and biochemical techniques.Read moreRead less

Subtropical regions in Australia, due to a warm climate, land and water availability, have the potential to produce a variety of agricultural produce, particularly fruit, to meet market demand. However adoption of fruit crops, many of which, including table grape, have temperate origins, requires intensive management. Despite years of agronomic R&D, production remains variable due to a lack of fundamental knowledge on how climate impacts on the development cycle, particularly flowering, required to produce fruit. This proposal will carry out basic research to provide knowledge that will enable consistent production and expansion of table grape and other temperate crop industries.Read moreRead less

It is estimated that the direct and indirect cost of diet-related diseases to Australia is between $2-3 billion per annum. One of the most important things that can be done to prevent diet-related disease is to encourage the population to eat more fruits and vegetables. The aim of this project is to examine the effect of price and perceived quality on the type and quantity of fruits and vegetables consumed, especially among low-income households. The project will employ modelling techniques that are novel to this product group and that will provide valuable insights to the constraints and opportunities for increasing fruits and vegetables intake, as well as benchmarks for future research.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
