飲料類金屬鋁罐食品容器之衛生安全

SURVEY ON SAFETY STATUS OF ALUMINUM FOOD CONTAINERS FOR BEVERAGE

近年來由於生活形態之改變，各種包裝材料成為日常生活之必需品，而金屬罐容器由於罐內之塗漆是由高分子合成樹脂與添加劑如顏料、無機添加劑、潤滑劑及溶劑等反應形成，可能會有反應剩餘之單體及添加物之殘留，這些殘留物均具有一定之毒性，我國在食品器具、容器及包裝衛生管理方面，對於有害物質均訂定限量標準。由於目前飲料類之金屬罐大部分以鋁罐為主，故本研究委託台灣省政府衛生處至全省各鋁罐製造工廠抽驗該類材質之包裝檢體共51件，依據行政院衛生署公告之「食品器具、容器、包裝衛生標準」進行溶出試驗，以了解市售該類食品容器之衛生安全狀況。結果顯示，砷、鉛及鎘均在合格標準之下；蒸發殘渣：4% 醋酸浸出液為5~16ppm，20% 酒精浸出液為 4~14ppm，水浸出液為 16ppm；氯甲代氧丙環單體、氯乙烯單體、酚及甲醛均未檢出。綜合以上結果，所抽驗之51件鋁製空罐均符合衛生標準。

To investigate the sanitation and safety of aluminum food containers, a total of 51 samples were examined. All tests followed the hygienic standards and the methods of food utensils, containers and packaging. The results showed that the contents of arsenic, lead and cadmium were below the hygienic limitation; the residues on evaporation were between 5-16 ppm for 4% acetic acid leaching test, 4-14 ppm for 20% ethanol leaching test and 16 ppm for water leaching test; the amounts of epichlorohydrin monomer, vinyl chloride monomer, phenol and formaldehyde were not detected. Fifty-one samples were all found to comply with the hygienic standards of food utensils, containers and packages.
