“…Similar method to evaluate the applied method accuracy in the analysis of wine samples was also used by Grindlay et al (2008), Grindlay et al (2014), and Ivanowa-Petropulos et al (2015), (2016). Also, the recovery test (as a spiking sample with standard solutions) was applied to the determination of metal in tea, wheat, wheat flour, and fruit juice samples using ICP OES technique (Martins et al 2015;Szymczycha-Madeja and Welna 2013).…”

In the present study, an inductively coupled plasma optical emission spectrometer ICPE-9820 with the mini-torch technology that significantly reduces the consumption of plasma gas to 7.0 L min respectively). The recoveries were between 88.2 and 110 %, 65.9 and 106 %, and 62.8 and 109 %, whereas the relative standard deviations (RSDs) varied between 0.04 and 4.62 %, 0.74 and 5.57 %, and 0.70 and 5.80 %, respectively, for the procedure of sample dilution, microwave digestion, and water bath digestion.

“…9,15 Determination of the total levels of inorganic constituents, such as Ca, Fe, K and P in food, is crucial to assess the possible impact of the food on human health. Various elements in cassava and flour samples from various countries have been determined using flame atomic absorption spectrometry (FAAS), [16][17][18][19] graphite furnace atomic absorption spectrometry (GF AAS), 20,21 inductively coupled plasma-optical emission spectrometry (ICP OES) [22][23][24][25] and inductively coupled plasma mass spectrometry (ICP-MS) [26][27][28][29] . However, the studies are scarce in the literature that determined the levels of inorganic constituents in cassava flour.…”

Resumo:The concentrations of Ca, Cu, Fe, K, Mg, Mn, P and Zn in 10 commercially available cassava flours (Manihot esculenta Crantz, Euphorbiaceae) were determined using inductively coupled plasma optical emission spectrometry (ICP OES). The elements were found in descending order of concentration, as K > Ca > P > Mg > Fe > Cu > Zn > Mn. Based on the recommended daily intake for adults, the values showed that 10 g day -1 cassava flour provides 5.3% of the daily intake of Cu, 0,5-1.2% for Fe, 0.5% for Ca, 0.9-1.2% for Mg, 0.6-0,8% for Mn, 0.6% for P, 0.2% for K and 0.2-0.3% for Zn. Based on the RDIs (Recommended Daily Intake) of the elements studied, the results indicate that cassava flour contains several essential elements, and the levels found in the cassava flours presents no risk to the human health. With the results of the multivariate analysis, it was possible to locate information about clusters and dissimilarities between the samples and between the variables, as well as to provide useful information for future studies on quality control and genetic improvement of cassava with better nutritional values.

“…Determination of nutrient and toxic elements in food samples can be carried out using inductively coupled plasma-optical emission spectrometry (ICP-OES) [8][9][10][11] inductively coupled plasma mass spectrometry (ICP-MS) [12][13][14], flame atomic absorption spectrometry (FAAS) [15][16][17], and graphite furnace atomic absorption spectrometry (GFAAS) [18][19][20][21]. Among the spectrometric techniques used for elementary determination, ICP techniques are outstanding due to their wide linear response, low limits of detection (LODs), multielementary capability, fast analysis, good precision, and accuracy [22].…”

Food security is a priority issue for sustainable global development. In rapid industrialization areas with high fallout of airborne particles, metal uptake by plants could strongly impact crop quality. In this study, concentrations of some heavy metals (Cu, Zn, and Pb) in flour samples supplied in Çorum, defined as one of the “New Industry Focus”, were investigated using inductively coupled plasma-optical emission spectrometry (ICP-OES) to determine the heavy metal contamination. The results showed that the concentration of Pb in all samples examined exceeded the maximum permissible limit. To monitor the increase in Pb concentration and its relationship with air pollution, a two-year laboratory experiment was conducted. It was found that the increase in Pb concentration of about 47% and 77% for two flour samples was consistent with the increase in annual average PM10 concentrations (55% and 82%) obtained from two stations.
