“…However, a chronic dietary addition of inorganic Se-compounds (like SeVI or selenite) at rates of more than 5 mg Se · kg -1 can be hepatotoxic and teratogenic in animals and humans (Whanger, 2004;Navarro-Alarcon and Cabrera-Vique, 2008). In contrast to selenide, selenite and SeVI, Se coupled with methionine (Se-Met) is less reactive, and because tRNA Met (a methionine transfer RNA) does not discriminate between Se-Met and Met, dietary Se-Met is incorporated into body protein in place of Met (Weiss and Hogan, 2005;Navarro-Alarcon and Cabrera-Vique, 2008;Thiry et al, 2012).…”

“…The balance between UFA (especially LPUFA and n-6PUFA) and pro-or antioxidants (like Secompounds) in feed is the critical factor influencing the quality of farm animals' meat (Traulsen et al, 2004;Niedźwiedzka et al, 2008;Czauderna et al, 2009Czauderna et al, , 2012aThiry et al, 2012;RozbickaWieczorek et al, 2014). Essential physiological roles of half of the Se-proteins are to maintain the appropriate metabolism of arachidonic acid (AA) and low levels of free-radicals within cells, so, reducing oxidative stress and peroxidative damage of lipids (Traulsen et al, 2004).…”

“…Still, it is currently accepted that Se bioavailability, intake and metabolism are heavily dependent on its chemical forms (Finley 2006;Thiry et al 2012;Kieliszek and Błażejak 2013), which can be organic, such as selenoaminoacids, Se-methyled forms and complex selenoproteins, or inorganic, such as selenite (Se IV ) and selenate (Se VI ) (Sager 2006;Pedrero and Madrid 2009). Selenium contents in grazing animals and plants are highly correlated with the available Se in soils (Durán et al 2013), therefore many countries feature an average Se intake that is insufficient to achieve an adequate activity of protective selenoenzymes.…”

Characterization of selenium-enriched wheat by agronomic biofortification

Agronomic biofortification of staple crops is an effective way to enhance their contents in essential nutrients up the food chain, with a view to correcting for their deficiencies in animal or human status. Selenium (Se) is one such case, for its uneven distribution in the continental crust and, therefore, in agricultural lands easily translates into substantial variation in nutritional intakes. Cereals are far from being the main sources of Se on a content basis, but they are likely the major contributors to intake on a dietary basis. To assess their potential to assimilate and biotransform Se, bread and durum wheat were enriched with Se through foliar and soil addition at an equivalent field rate of 100 g of Se per hectare (ha), using sodium selenate and sodium selenite as Se-supplementation matrices, in actual field conditions throughout. Biotransformation of inorganic Se was evaluated by using HPLC−ICP-MS after enzymatic hydrolysis for Se-species extraction in the resulting mature wheat grains. Selenomethionine and Se VI were identified and quantified: the former was the predominant species, representing 70-100 % of the total Se in samples; the maximum amount of inorganic Se was below 5 %. These results were similar for both supplementation methods and for both wheat varieties. Judging from the present results, one can conclude that agronomic biofortification of wheat may improve the nutritional quality of wheat grains with significant amounts of selenomethionine, which is an attractive option for increasing the Se status in human diets through Se-enriched, wheat-based foodstuff.

“…On persons, bioavailability can be estimated by measuring selenium levels in blood and in body tissues. The bioactive part of selenium is converted into biologically active selenometabolites (Thiry et al, 2012). Additionally, according to Ruby et al (1999), the bioaccessible fraction of an element is the fraction that is soluble in the intestine and that is therefore available for subsequent processes of absorption through the intestinal mucosa (Figure 2).…”

Selenium is an antioxidant trace mineral with important biochemical functions related to the enzymatic activity of selenoproteins. Due to a wide variation in the content of selenium from different plant sources, there is a high risk of deficiency of this nutrient in human nutrition, and particularly in the early childhood. Thus, the use of biofortified staple foods, namely selenium rice flour can be understood as an important trait, namely for food production for infants. This study aims to evaluate the importance of selenium biofortified rice flour, further considering baby foods.
