Mineral profile of black currant (Ribes nigrum L.), growing in the Far Northeast of Russia

Abstract

The aim of the study is to evaluate the mineral profile of black currant fruit (Ribes nigrum l.) growing in the North-East of Russia, on the territory of the Magadan region. Material and methods. Berry samples were collected within the forest zone of Magadan from wild plants. Atomic emission spectrometry and inductively coupled plasma mass spectrometry were used to determine the content of 25 minerals and trace elements in the objects under study. Results and discussion. The content of minerals - calcium (64.2 mg%), magnesium (21.6 mg%), sodium (0.3 mg%), phosphorus (51.8 mg%) and trace elements - iodine (1.0 μg%), zinc (0.29 mg%) in black currant fruits (Ribes nigrum l.), growing in the forest zone of Magadan, corresponded to the database of chemical composition of Germany, Spain, Norway, Russia, USA, France, Sweden, Estonia. The content of potassium (180.3 mg%), copper (0.05 mg%), iron (0.4 mg%), manganese (0.1 mg%) was below the reference ranges. A portion (100 g) of black currant berries satisfies the daily requirement of an adult for selenium by 11%, potassium by 7%, phosphorus by 6.5%, calcium, magnesium, copper, manganese - by 5%, iron by 3-4%, zinc by 2%. Conclusion. The obtained data on the content of minerals and trace elements in the berries of wild black currant growing in the North-East of Russia, can be an addition to and clarification of the information available in the literature and database on the chemical composition of foods.
