What is it about?
We present a method for identifying tuna meat samples, which have undergone fraudulent wet salting with nitrite. The method uses headspace-GC/MS for the determination of nitrous oxide, which is formed as the final product of the two-step reduction nitrite (added agent) to nitric oxide (ligand) to nitrous oxide (target compound).

Why is it important?
In Europe, treatments of tuna with carbon monoxide or by wet salting with nitrite are illegal and considered as food fraud. Whereas analytical methods exist to uncover carbon monoxide gassing, no such tool has yet been reported for identifying nitrite treatment.
Perspectives
Our new method would finally close the existing law enforcement gap and improve consumer protection in this respect.
