Guelph – Now that scientists can barcode and catalogue the unique DNA sequence of any living being, they’re putting the technology to the test to authenticate food products.
University of Guelph professor Steven Newmaster is helping food manufacturers verify the products they use don’t contain any adulterated ingredients.
University of Guelph scientists invented DNA barcoding in 2003, starting with animals and plants and identifying more than 60,000 plant species to date. Newmaster, the director of the Natural Health Products (NHP) Research Alliance at Guelph, wondered how the catalogued information could be used by the food and NHP industry.
He began by using the previous barcoding work to create new libraries of DNA information for commercial plant species used in agriculture and food. Now, he’s successfully created a new tool to deal with food fraud – the practice of using lower cost substitute ingredients in the food industry – that will soon be installed by food manufacturers for on-site testing.
“With a shrinking food supply and a population headed to nine billion, there is tremendous pressure on the supply chain, and contamination or substitution of ingredients may become more tempting for some companies,” says Newmaster. Continue reading
