| Abstract: | Component analysis of coix seed produced in Zhuanghe was done in this experiment.The contents of water,ash,lipid,fiber,protein were determined according to national standard methods.Eight kinds of trace elements(Zn,Na,Mg,Fe,Ca,Cu,Mn,Sr) in the coix seed were analyzed by flame atomic absorption spectrophotometry(FAAS).The results showed that the contents of water,ash,lipid,fiber,protein were 10.73 %,1.64 %,5.56 %,0.44 %,14.26 %,respectively.The contents of Zn,Na,Mg,Fe,Ca,Cu,Mn,Sr were 43.24,118.64,1 193.60,2... |
