2005-11-1 A method has been developed for the direct determination of Se in nutritionally relevant foods by graphite furnace atomic absorption spectrometry. Tungsten/rhodium carbide coating on the integrated platform of a transversely heated graphite atomizer or W coating with co-injection of Pd(NO 3) 2 were used as a permanent modifiers.

Abstract. Selenium (Se) is a non-metal which was first discovered as a by-product of sulphuric acid production. In 1950, it was considered as an essential mineral found in cereals, nuts, legumes ...

2014-5-8 The main source of selenium intake for humans is through plant foods in which the plants concentrate the selenium found in soil or taken from groundwater used for irrigation. Selenium (Se) contamination of potable water supplies at concentrations above the current MCL of 0.05 milligram per liter (mg/L) is rare.

Selenium levels in different food items *DV: Daily value. DVs are reference numbers developed by the Food and Drug Administration (FDA) to help consumers determine if a food contains a lot or a little of a specific nutrient. The DV for selenium is 70 μg. Most food labels do not list a food's selenium content.

2021-9-25 The use of by-products reduces costs for the cultivation of Se-enriched mushrooms, whose consumption could reduce problems associated with Se deficiency. Treatments to decrease by-products contamination, such as sterilization, are also expensive and thus are not accessible for small producers. In this way, this work aimed to evaluate the influence of Se at 25 mg kg−1 (sodium selenite) on the ...

2011-9-7 The most commonly used methods for assessing the selenium (Se) status in humans involve analysis of Se concentration, selenoprotein activity, and concentration in the blood and its compartments. Recently, it has been suggested that the expression of selenoprotein mRNA in circulating blood leukocytes could differently reflect Se status, due to prioritization of specific selenoprotein synthesis ...

Use of foods containing phytosterols is a relatively recent development in human nutrition (Gilbert and others 2005). Phytosterols as functional ingredients in foods appear to be a practical and safe option for lowering cholesterol levels in the population (Quilez and others 2003).

The essential trace element, selenium (Se), has multiple biological activities, which depend on the level of Se intake. Relatively low Se intakes determine the expression of selenoenzymes in which it serves as an essential constituent. Higher intakes have
