Content of macroelements and trace elements in samples of different species of frozen cephalopods Introduction: frozen cephalopods are one of the most highly consumed seafood products and they are a valuable source of nutrients. Cephalopods could contain metals such as macroelements (Na, K, Ca, Mg), essential trace elements (Fe, Zn, Mn, Mo) and non-essential trace elements (B, Ba, V). Because of the level of human consumption of frozen cephalopods, it is necessary to determine their metal contents and their dietary intake. Objectives: to determine the metal contents of four species of frozen cephalopods (cuttlefish, octopus, squid and shortfin squid) and their dietary intake, as well as studying the possible existence of statistical differences between the four studied species. Material and methods: the macroelement (Ca, K, Na and Mg) and trace elements (Fe, Zn, B, Ba, Mn, Mo and V) contents have been determined in 65 samples of frozen cephalopods by ICP-OES (Inductively Coupled Plasma – Optical Emission Spectrometry). Results: Na (2499 mg/kg wet weight) is the major macroelement found in cuttlefish. The most noteworthy trace element was Zn (7.08 mg/wet weight.) which was found in squid. Statistical differences between the studied species have been found in most of the metals studied. Conclusions: in terms of the recommended intake of seafood products such as cephalopods, the essential element intake is not noteworthy; in addition, the non-essential element intake is low and, consequently, does not pose a health risk to adults..

Abstract

Content of macroelements and trace elements in samples of different species of frozen cephalopods Introduction: frozen cephalopods are one of the most highly consumed seafood products and they are a valuable source of nutrients. Cephalopods could contain metals such as macroelements (Na, K, Ca, Mg), essential trace elements (Fe, Zn, Mn, Mo) and non-essential trace elements (B, Ba, V). Because of the level of human consumption of frozen cephalopods, it is necessary to determine their metal contents and their dietary intake. Objectives: to determine the metal contents of four species of frozen cephalopods (cuttlefish, octopus, squid and shortfin squid) and their dietary intake, as well as studying the possible existence of statistical differences between the four studied species. Material and methods: the macroelement (Ca, K, Na and Mg) and trace elements (Fe, Zn, B, Ba, Mn, Mo and V) contents have been determined in 65 samples of frozen cephalopods by ICP-OES (Inductively Coupled Plasma – Optical Emission Spectrometry). Results: Na (2499 mg/kg wet weight) is the major macroelement found in cuttlefish. The most noteworthy trace element was Zn (7.08 mg/wet weight.) which was found in squid. Statistical differences between the studied species have been found in most of the metals studied. Conclusions: in terms of the recommended intake of seafood products such as cephalopods, the essential element intake is not noteworthy; in addition, the non-essential element intake is low and, consequently, does not pose a health risk to adults..
