摘要: 通过在实验室模拟硫磺熏蒸的手段,采用微波消解电感耦合等离子体质谱法（ICP-MS）对硫磺熏蒸前后银耳中铅、砷、汞、镉、铬、铜6种有害金属含量进行测定。结果表明,随着熏蒸时间的增加,经过硫磺熏蒸的银耳砷的含量显著提高,汞含量也有一定程度的上升,而其他4种元素没有明显变化。硫磺熏蒸作为一种食品处理方法,其对食品品质的影响及安全性有待进一步的考量。Abstract: Six harmful metal elements, including Pb, As, Hg, Cd, Cr and Cu in tremella before and after sulphur fuming, which was simulated in laboratory, were analysised by coupled plasma mass spectrometry ( ICP-MS) after microwave digestion.The results showed that sulphur fumed tremella had an notable raise in arsenic content with mercury content increased as well, and did not changed significantly in the other 4 metals as the amount fuming time increased.As a food processing method, the influence of sulphur fuming on food quality and safety should be reserved for further consideration.
