Determination of Mineral Content in Indian Spices by ICP-OES

Abstract

Spices refer to all of the edible parts of a plant used for flavoring or coloring foods, including fruit, seed, root, bark or vegetable substance 1 . Some are often used as preservative against the action of harmful bacteria or prevents their growth 2 . The specific uses of spices tend to vary considerably among cultures and countries, medicine, religious rituals, cosmetics, perfumery and in foods. As food, ORIENTAL JOURNAL OF CHEMISTRY ABSTRACTVegetarian and non vegetarian Indian diet consists of various cereals and vegetables along with spices, often used in the preparation of curries. The nutritive potential of trace element has been evaluated using Inductively coupled plasma optical emission spectrometry (ICP-OES). In this study, 15 trace elements like As,Hg,Se,Zn,P,Pb,Cd,Fe,Mn,Cr,Mg,Cu,C,Na and K have been determined in Five Indian popular spices. The result shows that the spice Aniseed contains Phosphorous (2027.10±14.0 mg/kg), Iron (5.40±2.0 mg/kg), Magnesium (270.10±7.0mg/kg), Calcium (602.8±4.0 mg/kg), Sodium (365.10±3.0 mg/kg) and Potassium (887.80±11.0 mg/kg). The spice Poppy seeds showed Phosphorous content of (3980.0±13.5mg/kg), Iron (5.475±2.5 mg/kg), Magnesium (287.20±14.0 mg/kg), Calcium (690.50±4.0 mg/kg), Sodium (81.16±5.0 mg/ kg) and Potassium (746.70±6.0 mg/kg). The spice Cloves showed that it contains Phosphorous (6355.0±20.0 mg/kg), Iron (1.699±0.2mg/kg), and Potassium (318.01±5.0 mg/kg). The spice Ajwain seeds showed the presence of Phosphorous (1764.0±16.0 mg/kg), Iron (17.87±8.0 mg/kg), Manganese (5.729±2.6 mg/kg) and Calcium (1353.0±10.0 mg/kg), The spice Fenugreek seeds showed that it contains Phosphorous (2950.0±17.5 mg/kg) and Potassium (124.82±2.0 mg/kg). Heavy metals As and Hg are absent in all five spices. Heavy metals Cr, Cd and Pb are absent in Cloves, Fenugreek and Ajwain species. The results showed that the spice powder is a good source of calcium, potassium, magnesium, Iron and Phosphorous.

“…The instrument's operating conditions were followed as described by Kumaravel and Alagusundaram (2014) with slight modifications. Solid powders and oil samples were prepared by acid digestion using the method of Agemian, Sturtevant, and Austen (1980) and RubioRodriguez et al (2012), respectively, with some modifications.…”

Using Stripping Voltammetry to Determine Heavy Metals in Cooking Spices Used in Iraq

“…The highest variability and concentration found was that of iron, followed by manganese, zinc, and copper. These results were compared with the ranges currently available in the literature (Table 7) [4,5,[13][14][15][16][17][18][19][20][21][22][23].…”

“…An AI is given when the RDA cannot be set. Table 7 collects (in mg) the estimated daily intake of Iraqi consumers from Cu (0.192), Zn (0.809), Fe (4.89), Mn (1.07), Cr (0.009), Ni (0.029), and Co (0.004); together with the recommended dietary allowance (RDA) [54] for Cu (0.9), Zn (8)(9)(10)(11), and Fe (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18); the mean intake (AI) for Mn (1.8-2.3) and Cr (0.025-0.035); and the tolerable upper level (TUL) for Ni (1.0). None of the Dietary Reference Intakes (DRIs) were determined for Co due to lack of data of adverse effects and concern with regard to lack of ability to handle excess amounts.…”

Mild Acid Ultrasonic Assisted Extraction of Arsenic Residues in Different Parts of Hot Chilli Prior to Ultra-Trace Determination by Flow Injection-Hydride Generation Atomic Absorption Spectrometry

“…Thus, it is important to determine the species of arsenic in food because of their high toxicity. Various instrumental techniques, such as flame atomic absorption spectrometry (FAAS) 6 , inductively coupled plasma-optical emission spectrometry (ICP-OES) 7,8 , inductively coupled plasma-mass spectrometry (ICP-MS) 9 ,flow injectionhydride generation atomic absorption spectrometric (FI-HGAAS) 10 , UV-Vis spectrop-hotometry 11 , voltammetric method 12 and colorimetry incorporated with image processing 13 have been used to accurately and precisely determine As at trace levels in various samples.…”
