Starch gets a better rap from Aussie nuclear science

An Australian invention could revolutionise food manufacturing processes.The neutron Rapid Visco Analyser or nRVA allows scientists to monitor the behaviour of starches as they are cooked and could help manufacturers develop food with more health benefits. 

Innovation Minister Senator Kim Carr congratulated scientists at the Australian Nuclear Science and Technology Organisation who worked with manufacturer Perten Instruments to develop the nRVA. 

"This discovery could mean manufacturers will be able to make food more efficiently, with lower energy input. 

"It also gives manufacturers the power to consistently create starches with known health benefits, like those that have been proven to help counter bowel cancer," Senator Carr said. 

The nRVA uses neutrons from ANSTO's OPAL research reactor at LucasHeights to enable manufacturers to better understand food at the molecular level. 

Scientists employing neutron scattering techniques have been able to see how starches change when they're cooked. 

Dr Elliot Gilbert, food science project leader at ANSTO, explained that the nRVA analyses small samples - often of starch - under controlled test routines. 

"This is not a question of irradiating food but of exploring the properties of starch down to the molecular level. The nRVA could radically improve food manufacturing processes like measuring flour and grain quality for breakfast cereals, snack and animal foods," Dr Gilbert said. 

"This is a great example of collaboration between scientists and industry resulting in a new technology with the potential to benefit Australia," Senator Carr said.
