免洗餐具（聚苯乙烯及紙製食品容器）衛生條件之調查研究

SURVEY ON SANITATION STATUS OF POLYSTYRENEMADE AND PAPER-MADE PRODUCTS FOR FOOD UTENSILS

本調查研究旨在了解國產聚苯乙烯（Polystyrene）製免洗餐具是否符合現行食品器具、容器、包裝衛生標準；及紙製免洗餐具之衛生安全情形。檢體係從全省各縣市抽購計發泡聚苯乙烯餐具77件，不發泡聚苯乙烯餐具29件，並從工廠抽得聚苯乙烯塑膠粒1件，聚苯乙烯塑膠膜6件；另紙製餐具計抽得紙杯47件。經調查檢驗結果，發泡聚苯乙烯餐具不合乎塑膠類食品器具、容器、包裝衛生標準者計16件（占20.78％），其中溶出試驗不符規定者計7件（占9.09％），分別為60°C水浸出液蒸發殘渣項1件，95°C水浸出液蒸發殘渣項3件，95°C之4％醋酸浸出液蒸發殘渣項4件。材質試驗與規定不符者計9件（占11.69％），均為揮發性物質苯乙烯單體超過標準限量，另不發泡聚苯乙烯餐具不符該標準者計3件（占10.3％）均屬溶出試驗中蒸發殘渣超過標準限量。至於紙杯47件均符合日本紙製器具衛生標準之規定。 In order to investigate the sanitation status of disposable food containers, 166 samples including 77 foaming polystyrene food containers, 29 unfoaming polystyrene food containers, one polystrene granule, 6 polystyrene paper and 47 paper cups were examined. The results of the experiment were indicated as belows: 1) 20.78% of foaming polystyrene utensil samples were not corresponded to the hygenic standard of plastic food utensils, containers and packages. 9.09% of samples failed to meet the standard of evaporation residue of acetic acid and water at 60°C or 95°C and 11.69% of samples failed to meet the standard of volatile styrene mononer content. 10.3% of unfoaming polysyrene utensil samples were not corresponded to the hygenic standard of plastic food utensils, containers and packages. Three samples failed to meet the standards of evaporation residue of water, n-heptane and alcohol. 3) 47 paper cups were all corresponded to the Japanese hygenic standard of paper-made container.
