In this paper, The primary analysis of Opisthoplata orientalis Buron on the nutritional components, amino acid composition and content, the composition and content of fatty acids, and trace elementsThe results showed that the contents of crude protein, crude fat, moisture and ash were 80%、112%、377% and 493%. The Oorientalis contained 18 amino acids, the content of total amino acids was 3937886 mg/100 g, 8 essential amino acids to human, the essential amino acids and 2 kinds of quasi-essential amino acid were 471%,and the ratios of E/T were 062, the essential amino acid pattern of Oorientalis met the standard protein pattern recommended by FAO. The Oorientalis contain 11 kinds of fatty acids, including 7 kinds of unsaturated fatty acid, unsaturated fatty acid content of the total of 7478%, and the content of oleic acid was as higher as 6130%,in detection of 5 kinds of constant elements and 5 kinds of trace elements K, P, Mg, Ca, Na, Zn, Mn, Cu 8 element content is relatively rich, Fe content less, beneficial element of Se Oorientalis is an insect food and medical resource with good nutritional qualities |
