Analysis on Amino Acids and Metal and Harmful Elements of Gui Faeces Bombycis
metal elements and arsenic in Gui Faeces Bombycis to discuss the nutritional composition and usage security.Method:The amino acid components and metal elements(Cu
Fe
Mn
Zn
K
Na
Mg
Ca) were analyzed by amino acid analyzer and flame atomic absorption spectrometry
respectively.Heavy metal elements(Pb
Cd) and harmful element(As) were determined by Graphite furnace atomic absorption spectrometry.Result:Sixteen amino acid components were contained in Gui Faeces Bombycis
the total content was 7.95%
in which aspartic content was 12.45%.10 metal elements such as Fe
Mn
etc.Were determined in it
especially the content of Ca was up to 34 000 μg·g-1.The content of heavy metal elements was as follows:Cu 8.2 μg·g-1
Pb 3.1 μg·g-1
Cd 0.088 μg·g-1.The harmful element(As) was 0.28 μg·g-1 and much lower than the specified value.Conclusion:Gui Faeces Bombycis was rich in amino acids compositions and metal elements
however
its heavy metal and harmful elements were in the safe range.It could be used as raw materials of health products and drugs due to its safe and effective character and abundant nutritional value.
