“…To date, the majority of the studies on quantitative analysis of salts have used inductively coupled plasma optical emission spectroscopy (ICP-OES) and atomic absorption spectroscopy (AAS). 4,5,[12][13][14] Other techniques used for quantitative analysis of salt are inductively coupled plasma mass spectroscopy (ICP-MS), 15 instrumental neutron activation analysis (INAA), [16][17][18][19] combination of chromatography and spectrophotometry, 8,[20][21][22] and gas chromatography-mass spectrometry (GC-MS). 25 Fourier transform near-infrared (FT-NIR) spectroscopy, 5 laserinduced breakdown spectroscopy (LIBS), 6,7,9,23 and a combination of laser ablation inductively coupled plasma mass spectroscopy (LA-ICP-MS) and LIBS 24 have been used for classification of salts.…”

“…In this analysis, barium chloride (BaCl 2 ) is added to aqueous solution of edible salts and makes insoluble particles of barium sulfate (BaSO 4 ) that scatter light. 4,15 This method would provide inaccurate results for salt samples containing relatively large amounts of S 2– . ICP-OES, ICP-MS, and AAS have been used to analyze metallic elements in edible salts.…”

We evaluated the performance of laser ablation analysis techniques such as laser-induced breakdown spectroscopy (LIBS), laser ablation inductively coupled optical emission spectrometry (LA-ICP-OES), and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), in comparison with that of ICP-OES using aqueous solutions for the quantification of sulfur (S) in edible salts from different geographical origins. We found that the laser ablation based sampling techniques were not influenced by loss of S, which was observed in ICP-OES with aqueous solutions for a certain salt upon their dissolution in aqueous solutions, originating from the formation of volatile species and precipitates upon their dilution in water. Although detection of S using direct laser sampling with LA-ICP-MS has well-known isobaric and polyatomic interferences, LIBS and LA-ICP-OES showed good accuracy in the detection of S for all salts. LIBS also provided the ability to identify the dominant chemical form in which S is present in salts. Correlation between S and oxygen, observed in LIBS spectra, provided chemical information about the presence of S or [Formula: see text], which are associated with the origin and quality of edible salts.

Table salts with their specialty flake size, textures, flavors, and colors can be considered a gastronomy niche food already increasing in demand worldwide. Being unrefined, they can contain trace elements potentially both healthy and toxic. In this study, 12 mineral elements (Al, Ca, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn) in 10 different salts commercially available in southern Italy namely, Atlantic grey, Baule volante, Guerande, Hawaiian pink, Hawaiian black, Himalayan pink, Maldon, Mozia, Persian blue, and smoked salts were analyzed by inductively coupled plasma mass spectrometry (ICP-MS) and thermal decomposition amalgamation-atomic absorption spectrophotometry (TDA-AAS). The concentration of mineral elements was variable according to the type of salt and its geographical origin. Co, Cr, Cu, Hg, Pb, and Se levels were tolerable and Al, Ca, Fe, Mn, Ni, and Zn ranged significantly among the samples. Persian Blue and Atlantic Grey salts showed elevated levels of Fe and Zn; their intake can be helpful in some specific conditions. Nevertheless, Ni levels were high in Persian Blue and Smoked salts. Pb exceeded the maximum level in all samples. Additional monitoring analyses of mineral contents in table salts are recommended for human health.
