市售耐熱塑膠袋之衛生化學調查

DETECTION OF PENICILLIN CONTAMINATION IN GENERAL PRODUCTS

近年來國內塑膠類材質使用於食品之包裝已日益普遍，雖使吾人飲食生活素質提高許多，但該類包裝材料是否會釋出有毒物質直接污染食品，相對的亦令吾人疑慮與關注。本調查係針對加熱食品使用高密度耐熱塑膠袋作為容器之衛生安全調查。耐熱塑膠袋主以聚乙烯或聚丙烯塑膠材料製成，此類材質柔軟度佳，無臭、無味，對一般溶劑具抗力，且耐水汽性良好，為極佳之包裝材料。耐熱塑膠袋係用高密度聚乙烯或聚丙烯經吹袋壓出法（Blow Film Extrusion Procedure成型，為市面上使用極為普遍之加熱食品容器。本次調查於七十四年三月至五月間於台灣北部地區採樣201件，依據行政院衛生署73.3.30衛署食字第467593號公告食品器具、容器、包裝篇生標準（見表一、表二）及日本食品衛生小六法（1982）予以檢驗；結果發現不合乎食品器具，容器、包裝衛生標準者僅兩件，佔百分之一，均為浴出試驗蒸發殘渣項超過標準限量（30ppm以下）分別為95°C、30分鐘4％醋酸浸出液蒸發殘渣51ppm及59ppm，95°C、30分鐘水浸出液蒸發殘渣40ppm及46ppm（見表三），至於其他溶出試驗項包括高錳酸鉀消耗量（見），重金屬、甲醇及正庚烷蒸發殘渣（見表三）等項以及材質試驗項包括鉛、鎘（見表五）等二項均與規定相符。 The goal of the survey was to understand heat-resistance plastic bags which were used in heating food whether there were migration toxic substance or not. Two hundred and one samples in the northern Taiwan area were purchased and analyzed. The results of the experiment indicated the 1% of polyethylene-made heat-resistance plastic bags failed to meet the hygenic standard of plastic food utensils, containers and packages. Two samples failed to meet the standard of evaporation residue of 4% acetic acid and water at 95°C, 30'.
