Abstract
Abstract This study was designed to determine the 11 metal elements (Al, Cr, Mn, Fe, As, Ni, Cu, Zn, Cd, Sb, and Pb) in soy sauce and their migration from the containing glass bottles. Inductively coupled plasma mass spectrometry (ICP-MS) was applied for the determination of the elements and one-factor-at-a-time method was employed for optimizing the ICP-MS parameters in migration experiment and microwave digestion experiment. The developed method was successfully applied to determine the content of 11 elements. The results showed that the experiment had excellent correlation and sensitivity. The accuracy of the elements in the migration study and test of soy sauce itself ranging from 84.25% to 118.75% was satisfied, and the precision of the method was validated and the RSD was no more than 15.5%. The concentration of all the detected metal elements migrated from the glass bottles were between 0.3450 and 2.398 ng·mL−1, and the risk assessment indicated that the metal elements in soy sauce had no risk to the public health. The proposed methodology in this study was successfully applied for the quality control for metal elements in soy sauce and the containing glass bottles for the first time, and a research method suitable for soy sauce consumption process control and risk assessment has been established.
