The Position:
This position is for up to 24 months and will work closely with leading Research Scientists in their respective field. The postdoc will carry out innovative, impactful research of strategic importance to CSIRO with the possibility of novel and important scientific outcomes. Findings will be presented in appropriate publications and at conferences.
Rice bran constitutes about 5-10% of brown rice, which is the most nutritious part of a rice grain as it is rich in oil, protein, fibre, vitamins, minerals and highly potent antioxidants. Although the health benefits of consumption of wholegrains are well documented, the level of consumption in some sectors of the community remains low. Commercial food preparation using rice bran oil or incorporating rice bran in food production is mainly hampered by the poor oxidative stability due to the presence of high level of polyunsaturated fatty acids that are prone to auto-oxidation and responsible for the undesirable rancid smell and bitter taste that renders the bran unsuitable for consumption. CSIRO has generated rice lines with significantly lower levels of polyunsaturates, which could be used for in-depth analysis in terms of oxidative stability and potential impacts on the shelf life of rice bran oil, whole grain brown rice and associated food products. In collaboration with International Rice Research Institute (IRRI), further development of high oxidative stability rice through numerous biotechnological approaches will be evaluated. Further, rice bran contains significant levels of gamma-oryzanol and Vitamin E as important antioxidants. The genetic variation and oxidation-inhibiting effects of these valuable oil-soluble antioxidants on rice bran oil and processed food products derived from whole grain rice/rice bran will be evaluated. The genetic manipulation of gramma-oryzanol biosynthetic pathway will also be explored. Following concept-proof experiments, a non-GM strategy employing a powerful TILLING platform uncovering rice mutants will be carried out in collaboration with the Chinese Academy of Sciences (CAS). In summary, this project aims to develop genetic and processing technologies for oxidatively stable rice bran which could be a feedstock to derive new foods and or food ingredients with health promoting properties.
