Abstract:  Aspongopus chinensis Dallas on the crude protein, crude fat, amino acid composition and content, the composition and content of fatty acids, VA, VE, VB1, VB2, trace elements Fe, Cu, Zn, Pb , Hg, As content and organochlorine pesticide residues in, and so were determined. The results showed that:Aspongopus chinensis Dallas contains 44.3% crude protein, 18 kinds of amino acid composition, the content is more amino acids serine 20.40%, The 15.52%, and lower levels of tryptophan and valine, respectively the 0.30% and 0.70%;With fat 53.0%, the oil contains cardamom acid (C14:0), 14-one acid (C14:1), palmitic acid (C16:0), soft resin oleic acid (C16:1), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2), peanuts acid (C20:0), 22 acid (C22:0), erucic acid (C22:1), 22-second acid (C22:2) and 24 acid (C24:0), 12 kinds of fatty acid, including six kinds of unsaturated fatty acid, unsaturated fatty acid content of the total fat of 57.1 %;With VA 214.4 mg/kg, and VE, VB1, VB2 content less;containing Fe, Cu, Zn several trace elements and toxic elements Pb content of 4.0 mg/kg;organochlorine pesticide residues were only alpha-BHC the detection, content less. Application of E/N, and the CS and AAS method to evaluate their nutrition, E% 42.38%, E/N is 0.736, in line with FAO/WHO reference to the protein pattern.
