Abstract

This study of this research is based on determination of heavy metals in dried longan by Flameless Atomic Absorption Spectrometry.  The heavy metals, Arsenic Cadmium Copper Zinc, and Lead (As, Cd, Cu, Zn and Pb) were determined in pulp of three samples.   There was no significance difference of concentrations  in the mean difference of the 5 heavy metals. By considering after the Codex Stan 230-2001, there was found that 4 heavy metals Cd, Cu, Zn and Pb not higher than the standard value but As, which making harmful to the lungs, skin, kidneys, and liver of the human body, was higher. However, Cadmium and Lead level being found in three samples, making it harmfuls as a food since lead is toxic at even small level. The result showed that Cadmium and Lead level were no significance difference. By the way, their levels below 0.50 and 0.1ppm in order (Codex Stan 230-2001), thus they were not produced cancer cells in human being. This data should be used to build database for dried longan in order to ensure the quality of food.
