“…A non-destructive energy-dispersive X-ray fluorescence (ED-XRF) spectrometry is a nuclear analytical technique was used for macro elements calcium and potassium analysis in food samples such as fruits, vegetables [ 60 ] and cumin spice [ 45 ]. Good comparability with Neutron Activation Analysis (NAA) and AAS showed by statistical results confirming no significant difference between EDXRF and both NAA/AAS methods [ 60 ].…”

Food composition database (FCD) provides the nutritional composition of foods. Reliable and up-to date FCD is important in many aspects of nutrition, dietetics, health, food science, biodiversity, plant breeding, food industry, trade and food regulation. FCD has been used extensively in nutrition labelling, nutritional analysis, research, regulation, national food and nutrition policy. The choice of method for the analysis of samples for FCD often depends on detection capability, along with ease of use, speed of analysis and low cost. Sample preparation is the most critical stage in analytical method development. Samples can be prepared using numerous techniques; however it should be applicable for a wide range of analytes and sample matrices. There are quite a number of significant improvements on sample preparation techniques in various food matrices for specific analytes highlighted in the literatures. Improvements on the technology used for the analysis of samples by specific instrumentation could provide an alternative to the analyst to choose for their laboratory requirement. This review provides the reader with an overview of recent techniques that can be used for sample preparation and instrumentation for food analysis which can provide wide options to the analysts in providing data to their FCD.

“…Dried samples were crushed into the fine powder using mortar agate, and placed into plastic bottle. Preparation for NAA was carried out by weighing 25-50 mg of dried samples and put into 0.3 mL plastic vial then sealed by heating (Syahfitri et al, 2017). The standard for NAA was also prepared using ICP multi-element standard (E Merck), then dropped by pipetting 100 mL of standard into the vial.…”

“…Therefore, in this study sixteen samples of meat, spleen and liver from Brahman cross steers reared in intensive production system in Bandung were collected and analyzed using instrumental neutron activation analysis (INAA). INAA is one of nuclear analytical techniques that widely used in characterization of trace elements in several matrices of samples, it is highly sensitive, non-destructive, multi-elemental, accurate, and precise, and has a good limit detection (Syahfitri et al, 2017;Moon et al, 2015).…”

In this study the determination of micro mineral elements (selenium, iron and zinc) in meat, spleen and liver of beef were carried out. Brahman cross steers reared under intensive production system in feedlot for 87 days. Samples of meat, spleen and liver were collected from 16 steers aged 24-36 months with four types of feeding treatment, feeding without Se (group I) and feeding with additional supplementary of 0.3 ppm selenium for 25, 50 and 75 days (group II, III and IV, respectively). Samples characterization were carried out by instrumental neutron activation analysis (INAA) using irradiation facility in G.A Siwabessy Serpong reactor. Analysis results showed that there is an increasing of selenium content in meat and liver after 75 days feeding. The mean of selenium in liver for group I, II, III and IV were 0.13, 0.17, 0.20 and 0.31 mg/kg wet weight, respectively, while for liver were 0.43, 0.53, 0.60 and 0.70 mg/kg wet weight, respectively. The mean concentrations for iron in meat, spleen and liver were 11.85, 139, and 38.94 mg/kg, respectively, for zinc were 27.90, 21.70 and 25.27 mg/kg, respectively. In this study, the meat and liver contribute more than 100% of recommended daily allowance (RDA) of Se for children and adults. Spleen have contribution of RDA of Fe 53 to 154%, while the RDA of Zn is contributed mostly from meat by 21 to 56%.

“…[14][15][16][17] Energy dispersive X-ray fluorescence (EDXRF) spectrometry has been employed for food analysis, with a characteristic advantage of being a technique for nondestructive multielement determination in solid samples. The application of EDXRF in the food area encompasses the analysis of chocolate, cocoa powder and powdered cocoa drink, [18][19][20] crabs, [21] grain wheat and pearl millet, [22] mixed diets, [23] potato starch, [24] rice, [25] soybean, [26] vegetal foodstuffs, [27] vegetables, fruits and flesh foods, [28] wine and water, [29,30] wheat flour, [31] and coffee. [12,13,32] However, when the EDXRF analysis is performed on solid samples in the form of powder, the physical structure of the matrix needs attention, in terms of particle size and packaging, as matrix interference can be observed if the sample distribution is not homogeneous.…”

Direct multielement determination of Cd, Pb, Fe, and Mn in ground coffee samples using energy dispersive X‐ray fluorescence spectrometry

An analytical method was proposed for the quantification of Cd, Pb, Mn, and Fe in ground coffee samples using energy dispersive X-ray fluorescence (EDXRF) spectrometry. External calibration was possible using the coffee matrix itself as standards with samples previously analyzed by inductively coupled plasma optical emission spectrometry (ICP OES). The ground coffee samples were analyzed in the form of pellets, which were placed in the center of the EDXRF measuring cell for the determination of the analytes. The limits of detection were 62, 55, 86, and 76 μg/kg for Cd, Pb, Fe, and Mn, respectively. Good linearities were obtained for the calibration curves with coefficients of correlation (R) of 0.9959 for Cd, 0.9939 for Pb, 0.9929 for Fe, and 0.9909 for Mn. Precision, evaluated as the relative standard deviation (RSD) of 10 independent measurements of different cataloged samples with an approximate concentration of 400 μg/kg for each analyte, was between 6 and 14% (n = 10), demonstrating that the preparation of the samples in form of pellets was sufficient to perform analyses by EDXRF. The proposed method was applied in the determination of Cd, Pb, Fe, and Mn in ground coffee samples collected in Salvador, Bahia, Brazil. In a parallel comparative procedure, coffee samples were also analyzed by ICP OES after sample pretreatment by acid digestion. A paired Student's t test was carried out (confidence level of 95%, n = 5) and no significant difference was observed between the concentrations obtained by the proposed and comparative methods.
