The accurate determination of a toxic element in food has been important for the assessment of food safety. Accordingly the method for the reduction of toxic element in food also has been needed. Arsenic is well known as an element with high toxicity, but its toxicity depends on the chemical forms. Inorganic arsenic is more toxic than organic arsenic, thus the quantitation of inorganic arsenic in a food is critical. In particular, HIziki has been known to contain the inorganic arsenic. In this study, the determination of inorganic arsenic in Hiziki was performed, then the change of the concentration of inorganic arsenic was investigated with the various pretreatment methods of Hiziki. The inorganic arsenic was separated by ion chromatography (IC), then detected by inductively coupled plasma mass spectrometry (ICP-MS). The different pretreament methods were the soaking, steaming, and boiling the Hiziki. The concentrations of inorganic arsenic in Hiziki were reduced to 50%, 30%, 74% of the original concentration by soaking, boiling, and steaming, repectively.
