The polymerase chain reaction (PCR) equipment amplifies fragments of DNA to confirm the meat source is precisely as claimed.
During PCR, by alternately heating and cooling the target DNA through a defined series of temperature steps, the source content or the presence of any undeclared animal protein, even as little as 0.1%, can be precisely confirmed.
Pat McNamara, operations manager at Exova’s Birmingham laboratory, said: “This accredited capability ensures a high level of accuracy and gives customers essential confirmation of the validity of the meat content of their products.
“There are benefits for the whole supply chain because we can provide documented proof of authenticity, avoiding any misjudgement and addressing any potential confusion regarding product contents.”
