November 2017 - UBC news: Food science students led by professor Xiaonan Lu used a laser-equipped spectrometer and statistical analysis to determine with 99 per cent accuracy whether ground beef samples included other animal parts. They were able to say with 80 per cent accuracy which animal parts were used, and in what concentration.
Their new method can accomplish all of this in less than five minutes, which makes it a potentially transformative food inspection tool for government and industry.
