Abstract:
Polyphosphates are permitted as food additives (Regulation EC No 1129/2011) but their
undeclared utilisation is considered fraudulent. They improve water holding capacity of the
seafood, preventing biochemical/physical changes during commercialization. The key objective
of this study was the detection of polyphosphate in various seafood categories, by means of highperformance
ion-exchange chromatography with suppressed conductometry (HPIEC-SCD)
coupled to Q-Exactive Orbitrap high resolution mass spectrometry (HRMS-Orbitrap). Ten frozen
cuttlefish samples did not reveal any treatment, while in ten frigate tunas, high concentration of
orthophospate was found. Unambiguous hexametaphosphate presence was demonstrated in
four prawn samples, while triphosphate was quantified (11.2±4 ug/g) in another four prawn
samples that contained orthophosphate (10225±1102 ug/g), as well. Other samples sporadically
encompassed polyphosphates profiles that varied according species and processing type. This
analytical approach provided sustenance in better understanding regarding utilization of
polyphosphates through HRMS fingerprinting of anionic species that would be specific in food
safety control.
