Latvian. Makroelementiem un mikroelementiem ir liela nozīme cilvēku ikdienas uzturā. Pasaulē 50% pārtikas produktu ikdienas uzturā sastāda tieši graudaugi. Pētījuma mērķis bija noteikt makroelementu un mikroelementu daudzumu dažādos graudos, kas selekcionēti un audzēti Latvijā Valsts Stendes graudaugu selekcijas institūtā. Pētījumā tika izmantoti dažādi graudaugu veidi: rudzi (n = 45), mieži (n = 54), vasaras kvieši (n = 27), ziemas kvieši (n = 53), tritikāle (n = 45) un auzas (n = 42); kopā n = 266. Graudos tika noteikti šādi makroelementi un mikroelementi (minerālvielas): Cd, Pb, Ni, Cr, Al, Cu, K, Na, Mn, Fe, Zn, Mg, Cu. Minerālvielu saturs graudos bija būtiski atšķirīgs (p ir mazāks nekā 0,01 vai p ir mazāks nekā 0,001). Dominējoši augstākais minerālvielu saturs tika konstatēts auzu un zemākais — rudzu graudos. Iegūtie pētījuma rezultāti paplašinās iespēju pārtikas un uztura zinātniekiem izvērtēt graudu pārstrādes produktos esošo un ar uzturu uzņemto makroelementu un mikroelementu daudzumu un to biopieejamību organismam.

Cereal-based foods have great importance in the compensation of micro- and trace element deficiency, because 50% of the foods produced worldwide are made up of cereal grains. The aim of the research was to determine the concentration of macro-elements and trace elements in different cereals cultivated in Latvia. Various cereals were used in the research: rye (n = 45), barley (n = 54), spring wheat (n = 27), winter wheat (n = 53), triticale (n = 45) and oats (n = 42). Thirteen macro- and trace elements (Cd, Pb, Ni, Cr, Al, Cu, K, Na, Mn, Fe, Zn, Mg, Ca) were determined in cereal grain samples (n = 266). Macro-elements and trace elements varied significantly (p is less than 0.01 or p is less than 0.001). The highest concentrations of macro- and trace elements were found in oats and the lowest in rye. The obtained data will expand the opportunity for food and nutrition scientists to evaluate content of the examined elements in grain products, and dietary consumption (bioavailability) of the examined macro-elements and trace elements.
