鋁製食品容器重金屬溶出試驗之探討
Study on the Migration Test for Heavy Metals in Aluminum-Made Food Containers
摘要
2011年5月10日自由時報報載：網路流傳，鋁製容器加熱會釋出鋁離子，長期累積體內有導致老年癡呆症可能，宜蘭縣政府消保官要求相關單位重視全國性飲食危機。為消弭消費者之疑慮，本研究進行鋁製食品容器之溶出試驗，模擬使用鋁製食品容器烹調時是否會造成鋁及其他重金屬之溶出，係參考行政院衛生署93.05.26署授食字第0939311138號公告「食品器具、容器、包裝檢驗方法—金屬罐之檢驗」方法，分別以水及0.5%檸檬酸溶液為溶出液，於95°C溶出30分鐘，再將溶出液以感應耦合電漿質譜儀檢測砷、鉛及鎘含量，並以感應耦合電漿放射光譜儀檢測鋁含量，結果顯示：7件市售鋁製食品容器並無砷、鉛及鎘之溶出，僅有微量鋁之溶出，由於鋁於消化道之吸收率極低，短時間加熱鋁製食品容器其溶出量並不會對人體造成危害。

According to Liberty Times on May 10th, 2011, an issue was circulating on the internet that aluminum containers will release aluminum ions during heating, leading to Alzheimer's disease due to long-term accumulation of aluminum ions in the human body. The Ilan County Government Consumer Ombudsman has thus asked related agencies to pay attention to this dietary issue. For relieving consumer concern, this study was to perform the migration test of aluminum-made food containers by simulating the migration of heavy metals from these containers. We referred to ”Method of Test for Food Utensils, Containers and Packages-Test for Metal Cans” announced by the Department of Health Food No. 0939311138 on May 26th, 2004, and selected water and 0.5% citric acid as the migration solvents. The migration conditions for the two solvents were both set at 95°C for 30 min. The inductively coupled plasma mass spectrometer was employed to determine arsenic, lead and cadmium migrated from aluminum-made food containers, and used inductively coupled plasma optical emission spectrometer to detect aluminum. The testing result showed that there was no arsenic, lead and cadmium migrated from seven aluminum-made food container samples purchased from markets, but only trace amount of aluminum was leached out. Due to very low absorption of aluminum in the gastrointestinal tract, the migration levels of heavy metals from aluminum-made food containers for short-time heating barely endanger human bodies.
