Određivanje cinka, bakra i selena u pseudožitaricama metodom induktivno spregnute plazme s masenom spektrometrijom

Pseudograins are a group of grains with a better nutritional profile than traditional grains such as corn, rice, or wheat. When it comes to the macronutrients, they are superior compared to other ingredients. They represent the source of biologically valuable amino acids, lipids and indigestible carbohydrates, which serve as prebiotic. Moreover, they have essential micronutrient composition, including trace elements – zinc, copper, and selenium. These elements were quantitatively determined in pseudograins such as buckwheat, quinoa, amaranth, and millet by the Inductive Coupled Plasma Mass Spectrometry (ICP-MS). Herein we report the results obtained. All examined pseudograins contain a substantial amount of zinc, copper and selenium. A significant amount of copper is present in the buckwheat (0.59 ± 0, 00 mg/100g) and selenium in amaranth (31.73 ± 2.43 mg/100g), which makes over 40% of the Recommended Daily Allowance (RDA). These microelements have an irreplaceable role in the physiological functioning of our organism, and their lack or excess can lead to numerous pathological conditions. Therefore, the pseudograins are an excellent source of these microelements and should be included in the everyday diet.
