Assimilation of Selenium, Copper, and Zinc in Rye Malt

Abstract Trace elements selenium, copper, and zinc are essential minerals for the human body. One of the means to increase the micronutrient content in diets is to add them to food raw materials, for example, to enrich grain with micronutrients during malt production. To obtain rye malt, 3 kg grain was soaked in 10 l water with addition of three mineral salts — sodium selenate (Na2SeO4), copper sulphate (CuSO4 5H2O), and zinc sulphate (ZnSO4 7H2O) at different concentrations and different combination of salts. The concentration of selenium, copper, and zinc was determined in rye malt. The obtained results were used to calculate the degree of assimilation of trace elements in rye malt. The interaction of trace elements selenium/copper and copper/zinc was studied. The total amount of selenium, copper, and zinc was analysed by inductively coupled plasma mass spectrometry (ICP-MS). Sample preparation for elemental analysis was performed by wet acid digestion in a closed microwave mineralisation system. The selenium assimilation degree in rye malt was within 10.6 to 12.2%. Accordingly, copper assimilation was 32.8 to 38.0% and zinc 49.3 to 57.0%. Simultaneous presence of selenium/copper and copper/zinc during rye grain soaking promoted the assimilation of each mineral, compared with only one mineral additive.

Abstract Background The aim of this study was to determine the amount of trace elements released from a traditional glass ionomer, a bulk-fill glass ionomer, a resin-modified glass ionomer, a glass carbomer fill and a compomer material stored in ultra-distilled water. Methods Ten cylindrical (10×2mm) specimens were prepared from each material. Each sample was stored in 50mL ultra-distilled water at 37°C for fourteen days, and rinsed twice daily. The amount of elements in the solutions was determined using inductively coupled plasma-mass spectrometry. Results Aluminum, boron, nickel, copper, zinc, barium and lead were detected in all solutions. The traditional glass ionomer and resin-modified glass ionomer released arsenic, the bulk-fill glass ionomer and compomer released selenium, and the resin-modified glass ionomer and compomer released antimony. Only the resin-modified glass ionomer released iron. Conclusion All materials tested released some trace elements, but the rates were quite low. Therefore, these glass ionomer materials can be used safely in dentistry.

Background: This study aims to determine and compare the levels of trace elements copper, zinc, selenium and chromium in GCF and serum of patients with periodontitis and healthy individuals. Methods: This cross sectional study includes 24 study subjects recruited from the patients reporting to the Department of Periodontics , Tagore Dental College Chennai. All the selected patients were subjected to a clinical examination done by a single examiner. The estimation of trace elements Copper, Zinc, Selenium and Chromium in GCF and serum is performed using Perkin Elmer optima 5300 Inductively Coupled Plasma Emission Spectrometer (ICPOES). Results: GCF and serum copper levels showed no significant difference in both periodontitis and healthy groups . Selenium levels tend to be the same in both groups. Serum zinc levels are more in periodontitis patients than healthy subjects (p less than 0.01). GCF chromium levels are found to be more in patients with periodontitis than healthy. Conclusions : More research is therefore needed to monitor the role of these trace elements C with an increased sample size to ascertain whether they are associated with a reduced risk of periodontitis.
