“…Consequently, the assurance of authenticity, high quality and purity of olive oil is a matter of great importance. For this purpose, investigating olive oil by means of ICP-MS analysis gains widespread scientific attention [ 9 , 126 , 127 , 128 , 129 , 130 , 131 , 132 , 133 , 134 , 135 , 136 , 137 , 138 , 139 , 140 ]. A considerable amount of literature has been published on Spanish, Italian, Tunisian, and Greek olive oil varieties.…”

“…Similarly, Nasr et al [ 9 ] concluded that Cu, Cr, Fe, Mn, Sr, V, and Zn facilitated to the accurately prediction of country of origin between European and Tunisian olive oils. In an attempt to certify the purity of the edible oils and to detect possible contaminations by mixing oils Llorent-Martínez et al [ 139 ] (2011) and de Souza et al [ 140 ] (2022) investigated the mineral composition of different types of edible oils and fats. Llorent-Martínez and co-workers observed correlations between Cr, Cu, Fe, and Mn and the different investigated oils.…”

Fraudulent practices are the first and foremost concern of food industry, with significant consequences in economy and human’s health. The increasing demand for food has led to food fraud by replacing, mixing, blending, and mislabeling products attempting to increase the profits of producers and companies. Consequently, there was the rise of a multidisciplinary field which encompasses a large number of analytical techniques aiming to trace and authenticate the origins of agricultural products, food and beverages. Among the analytical strategies have been developed for the authentication of geographical origin of foodstuff, Inductively Coupled Plasma Mass Spectrometry (ICP-MS) increasingly dominates the field as a robust, accurate, and highly sensitive technique for determining the inorganic elements in food substances. Inorganic elements are well known for evaluating the nutritional composition of food products while it has been shown that they are considered as possible tracers for authenticating the geographical origin. This is based on the fact that the inorganic component of identical food type originating from different territories varies due to the diversity of matrix composition. The present systematic literature review focusing on gathering the research has been done up-to-date on authenticating the geographical origin of agricultural products and foods by utilizing the ICP-MS technique. The first part of the article is a tutorial about food safety/control and the fundaments of ICP-MS technique, while in the second part the total research review is discussed.

Reversed-phase dispersive liquid-liquid microextraction (RP-DLLME) was proposed in the present work to separate and preconcentrate metal cations in sesame oil before their detection through ion chromatography-conductivity detection (IC-CDD). This method facilitates the direct extraction of cations like Na + , Pb 2+ , K + , Mg 2+ , and Ca 2+ from oil specimens into an aqueous micro-drop to inject into the chromatography column. Four parameters were included in the process as the pH of water, volume of water and THF, and centrifugation time through a response surface technique. Five replicated analyses were performed under optimized circumstances (1.5 mL THF as a disperser and 60 µL water at pH 9 as an extraction solvent). Thus, recoveries of 110%, 108%, 107.2%, 104.2%, and 106.8% were displayed with respective standard deviations of 10.3, 9.8, 7.3, 9.7, and 6.7 for K + , Na + , Mg 2+ , Pb 2+ , and Ca 2+ . The detection limits (3σ) for the method were 0.007 µg mL − 1 for K + , 0.001 µg mL − 1 for Na + , 0.011 µg mL − 1 for Mg 2+ , 0.008 µg mL − 1 for Pb 2+ , and 0.009 µg mL − 1 for Ca 2+ . The method could successfully determine the existence of metal cations in four sesame oil specimens.
