Tracing palm oil by its DNA

WURIs it possible to determine the exact origin of liquid commodities, like palm oil? Since palm oil volumes from different origins are mixed and mingled several times between plantation and refinery, this is difficult. “But not impossible”, is what scientists at WUR said. They developed a technique for DNA fingerprinting of liquid commodities, making it possible to determine its origin. Hidde worked with the WUR scientists to test their invention on palm oil samples from different regions in Malaysia. Once tried and tested, the ability to trace volumes back to their origin is a valuable tool to verify a claim that palm oil originates from a certified sustainable source.
