“…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.

Background: Bioactive compounds from vegetables have played a substantial role as therapeutic agents in drug discovery since it contains nutraceutical and nutraceutical properties. Cucurbitaceae family encompasses several edible plants that contain valuable natural compounds. Objectives: To evaluate the physicochemical and mineral composition on Momordica charantia fruit residues. Materials and Methods: The physiochemical composition and mineral composition were characterized by FTIR and optical emission spectrophotometer, respectively. The phenolics, flavonoids and total antioxidant activity were employed by spectrophotometrically. The green ultrasound assisted extraction was used for aqueous and 12% ethanolic extraction for evaluation of phenolic compounds by UPLC/MS. Results: The results revealed the minerals such as K, P, Ca, Na, Mg, Fe, Zn, Sr, Cu and Mn found in bitter melon. High contents of total phenolics content (683.820 to 1753.345 galic acid: quercetin (2:1)/100 g of sample) and total flavonoids (106.206 to 311.423 mg of quercetin/100 g of sample) were observed in peel aqueous extract. The aqueous extract of peel exhibited maximum inhibitory potential against DPPH radical (93% of inhibition) than ethanolic extract. This aqueous extract of peel also contains naringenin, catechin, epicatechin, p-coumaric, ferulic and chlorogenic acids which were reveled from UPLC/MS analysis. Conclusion: This study suggests that M. charantia residues are good sources of functional proteins, lipids, fibers and minerals, resulting in greater nutritional value. In addition, M. charantia is of great interest in its promising benefits for human health, due to its antioxidant capacity and bioactive compounds.
