[Determination of trace elements in mylabris before and after being processed].
OBJECTIVE
To discuss the processing principle of Mylabris by comparing the differences between the contents of 11 trace elements in Mylabris before and after being processed.


METHODS
Used Flame AAS, Graphite Furnace AAS and Hydride generation AAS to determine the content of Cu, Mn, Zn, Fe, Mg, Ca, K, Pb, Cd, As and Hg elements in Mylabris samples.


RESULTS
The sequence of 11 trace elements contents in the Mylabris samples from high to low was: K > Mg > Fe > Ca > Zn > Mn > Cu > Pb > As > Hg > Cd. In Mylabris after being processed, the contents of Pb, As, Hg, Cd and Fe elements decreased, Cu, Mg and Ca increased; In the head, legs and wings of Mylabris, the contents of Hg and Pb elements were higher than those of the other parts. The content of As in the inner wings was the highest.


CONCLUSIONS
The traditional processing method, stir-frying with rice and removing head, legs and wings is scientific.
