Summary: | This work focuses on the extraction of organic selenium compounds (selenomethionine, Se-Met) from Antarctic Krill and on the adsorption studies with several adsorbents. Various extraction methods such as ultrasound supported digestion were employed for the separation of Se-Met from krill samples. A novel procedure for the determination of Se-Met with bifunctional chromatography is provided. --- Selenium is a trace element with recognized nutritional essentiality for human health. High bioavailability of the selenium species encountered in marine products makes the qualitative and quantitative determination and the isolation of organic selenium compounds such as Se-Met a challenging subject. Antarctic krill (Euphausia superba) is a small crustacean living in the ecosystem of the Antarctic region of the Southern Ocean and is regarded as one of the most important protein sources of the future, because of its low cholesterol level and the high levels of essential amino acids and of polyunsaturated fatty acids. ... |
