Effect of processing on the distribution of cadmium in wheaten products
2006
Swinden, Lindsay Brownlees
An understanding of the cadmium levels in the Australian wheat crop and areas of elevated levels that may be of concern to health has great potential for both the export market and the domestic consumer in Australia. This understanding is most effective if the sources of the cadmium in the wheat, the fate of the cadmium during the milling process and how this affects the levels in bread products is also known. The objectives of this study were to investigate cadmium levels in wheat from Australian silo sites, determine if a correlation existed between cadmium level and soil type, pH and fertiliser usage and determine the reasons for any correlation. In addition, to determine if the cadmium was partitioned during the normal commercial milling process into the milling fractions and how this affected cadmium levels in bread.
