Fluorescent probe detection can authenticate canned tuna species within 24 hours

Researchers in the Molecular Biology Laboratory at AZTI-Tecnalia (Sukarrieta, Spain) have developed a fluorescent probe DNA detection method to authenticate canned tuna, with the ability to distinguish between albacore, yellowfin, bigeye, and other tuna species within 24 hours. Current genetic methods for establishing proper DNA identification can take several days to produce conclusive results, so the researchers' method has promising implications in the food canning industry.

Canned tuna is commonly produced using imported frozen tuna fillets, as they offer advantages in terms of productivity and yield. However, there is occasional difficulty in distinguishing between species visually, so errors may occur in labeling.

The researchers' DNA detection system has received accreditation from the National Accreditation Body (ENAC; Madrid, Spain). The method not only offers speed in identifying species, but also reliable, conclusive results to guarantee that products are properly labeled and ensure quality for consumers.
