Estimation of minerals and trace elements in selenium tea from the Enshi district, China, and its infusions by ICP-AES, GFAAS and INAA


, : Estimation of minerals and trace elements in selenium tea from the Enshi district, China, and its infusions by ICP-AES, GFAAS and INAA. Zeitschrift fur Lebensmittel Untersuchung und Forschung 197(5): 444-448

The Enshi district in Hubei province, China, is a selenium-rich area, producing Se black and green tea. 3 samples of green Se tea were analysed and compared with ordinary tea. Trace elements and minerals analysed by inductively coupled plasma atomic emission spectrometry (ICP-AES) were potassium, calcium, magnesium, sodium, phosphorus, sulphur, aluminium, manganese, iron, barium, strontium, copper, nickel, cobalt, zinc, molybdenum and chromium.
