New technique detects impurities in ground beef within minutes
Food science students were able to say with 80% accuracy which animal parts were used and in what concentration.
Researchers at the University of British Columbia (UBC), Canada, have found a better way to identify unwanted animal products in ground beef.
Food science students led by professor Xiaonan Lu used a laser-equipped spectrometer and statistical analysis to determine with 99% accuracy whether ground beef samples included other animal parts. They were able to say with 80% accuracy which animal parts were used and in what concentration.
