Background
Jamie Ayton heads NSW Department of Primary Industries edible oil research program.
He joined NSW Agriculture* in 1995 and has been involved in a number of olive oil research projects investigating the effects of cultivar, harvest timing, irrigation and processing on the quality of olive oil produced in Australia. He, along with the laboratories technical staff, has maintained accreditation from the International Olive Council (IOC) for the detection of adulteration in olive oil since 2001. He is also a founding member of the Wagga Wagga Olive Oil Sensory Panel, which has been accredited by the IOC since 2003.
Jamie also has an interest in the canola breeding and pre-breeding programs aimed at improving the quality and of Australian canola oil and meal.
*NSW Department of Primary Industries was formed in 2004 through an amalgamation of NSW Agriculture, Forestry Corporation, Minerals and NSW Fisheries.
