“…Copper deficiencies in early development have been shown to cause cardiovascular disorders, but it is also indicated that too little dietary copper intake may contribute to vascular disease later in life [ 11 ]. Because metals can have both positive and negative roles in the human body, it is important to identify them in foodstuffs to understand their impact on human health [ 12 ].…”

The biological activity of chocolates gains more and more attention of consumers. Its antioxidant properties depend, among other factors, mainly on the origin of cocoa and the characteristics that this origin gives to the final product. Therefore, the aim of the study was to measure and compare the total content of polyphenols, antioxidant activity, and key odorants of commercial chocolates made from blend cocoa with single-origin ones. The highest content of polyphenols was found in 90% blend cocoa chocolate and single-origin samples, while the lowest content was exhibited by 100% chocolate from blend cocoa mass. The highest antioxidant activity measured by 2,2′-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) and ferric reducing antioxidant power (FRAP) assays was observed in the sample of chocolate with 90% cocoa solids from blend mass, followed by single-origin chocolates. A high positive correlation between ABTS assay and the total polyphenol and phenolic acids’ content, as well as among the total content of polyphenols, flavonoids, and phenolic acids was found. Mineral composition analysis showed that dark chocolate is a valuable source of some elements, especially Mg, Fe, and Zn. Potentially toxic elements were not detected or below permitted limits. Moreover, it was noticed that the main volatile compound in all tested samples was acetic acid, but pyrazines were considered the most important group of chocolate odorants.

“…23 In the present study, using a 27.12 MHz ICP, RF power, and nebulizer argon flow rate were varied under the constant values of other plasma conditions. 24,25 Also, both viewing modes (axial/radial) were considered in this study. In order to eliminate the memory effect, the delay time for washing between samples and signal measurement was set to 30 s. Mermet 26 reported that plasma robust conditions can be represented by a Mg II 280.270 nm/Mg I 285.213 nm ratio (Mg II/Mg I) higher than 10.…”

“…As expected, the results showed a higher Mg II/Mg I ratio for the radially viewed configuration (Table 1). 24,25 Using an RF power of 1150 W, nebulizer gas flow was varied from 0.5 mL/min to 1.5 mL/min in intervals of 0.5 mL/min. The highest Mg II/Mg I ratio of 10.35 and 11.42 for axially and radially viewed ICP OES, respectively, was at the nebulizer gas flow of 0.5 L min -1 ( Table 1).…”

This study aimed to optimize and validate the inductively coupled plasma optical emission spectrometric method (ICP OES) for the simultaneous determination of eleven potentially toxic elements (Al, Cd, Cr, Co, Cu, Ni, Pb, Fe, Sb, Mn, and Zn) in lipstick samples. The method was evaluated by applying the standard addition method. The recoveries for all elements in lipsticks were between 90% and 110%, except for Cd and Pb they were <90% and >110%, respectively. The health risk assessment was determined by calculating the average daily intake (ADD), hazard quotient (HQ), and hazard index (HI). The highest mean value for ADD was for Fe (4.8 × 10-1 mg kg-1 day-1), and the lowest was for Co (9.3 × 10-6 mg kg-1 day-1). There was no significant toxic health risk for any of the elements (HQ < 1), except for Fe (HQ < 3) which indicates a potential health risk. Based on PCA, all potentially toxic elements have been classified in the three groups. The first group includes Fe, the second includes Al, and all other elements belong to the third group. The cluster analysis of the elements provided the identical grouping that was obtained on the basis of PCA. Two separate clusters were obtained when cluster analysis was applied to the analyzed samples. The first cluster contained the only sample that was brown. The second cluster was divided into two sub-clusters. The first sub-cluster included the samples belonging to category I regarding the price, while the second sub-cluster included the samples belonging to category II and III regarding the price.

“…The most applied methods for the determination of heavy metals in food products and herbal plants are inductively coupled plasma‐mass spectrometry (ICP‐MS) (Lo Dico et al, ; Roleda et al, ), atomic absorption spectrometry (Divrikli, Horzum, Soylak, & Elci, ; Duran et al, ; Huang, Pan, Wu, Han, & Chen, ), and potentiometric stripping analysis (Munoz & Palmero, ). Inductively coupled plasma‐atomic emission spectroscopy (ICP‐AES) or inductively coupled plasma‐optical emission spectroscopy (ICP‐OES) technique is widely applied in the analysis of heavy metals in animal and vegetal products (meat, milk, and chocolate), air, water, and soil (Jevrić, Podunavac‐Kuzmanović, Švarc‐Gajić, & Kovačević, ; Mrmošanin et al, ; Podunavac‐Kuzmanović et al, ; Rouessac & Rouessac, ). This technique provides the analysis of multiple elements and also provides low detection limits, good stability, and limited spectral interferences (Rouessac & Rouessac, ).…”

Waffles, cookies, and crackers are considered to be one of the most often consumed confectionery products. Their complex composition in terms of raw materials used for their production often implies more than one source of heavy metals that end up in the final product. Therefore, the analysis of the heavy metals in these types of products is necessary. The present study deals with the determination of the correlations between the content of essential metals with potential toxic effects (copper, iron, zinc, manganese, and cobalt) determined by inductively coupled plasma‐atomic emission spectrometry in waffles, cookies, and crackers collected from the market in Autonomous Province of Vojvodina, Republic of Serbia. The concentrations determined were in the following ranges: Cu (0.299–0.5015 mg/kg d.w.), Fe (3.301–65.35 mg/kg d.w.), Zn (1.962–15.58 mg/kg d.w.), Mn (1.406–27.7 mg/kg d.w.), and Co (0.01–0.26 mg/kg d.w.). The mutual dependence of their concentrations was determined by chemometric linear and nonlinear regression methods which showed to be useful in the fast and easy determination of iron, manganese, zinc, and cobalt concentrations in the studied groups of confectionery products. Practical applications The practical application of the established chemometric models is reflected in the possibility of predicting the concentration of one metal in waffles, cookies, and crackers based on the concentration of the other one. In this way, the additional experiments can be avoided and the concentration of particular metal can be precisely determined, which is confirmed by the internal and external statistical validation procedures of the established chemometric models.
