中文摘要 | 市售可用於微波爐加熱之聚氯乙烯(polyvinyl chloride, PVC),聚偏二氯乙烯(ployvinylidene chloride, PVDC)及聚乙烯(polyethlene, PE)保鮮膜,和聚丙烯(polyproylene, PP),聚苯乙烯(polystrene, PS)之微波器皿,與低油脂食品擬似物蒸餾水,及高油脂食品擬似物-橄欖油,直接接觸後,置於微波爐中加熱,加熱後之食品擬似物經乙醚或甲醇溶劑萃取,並以氣相層析儀及氣相層析/質譜儀分析,發現橄欖油及蒸餾水與PVC保鮮膜接觸加熱後皆可檢測出塑化劑?酸二辛酯(dioctyl phthalate, DOP)之存在,與PVC加熱後,於橄欖油內檢測出乙醯檸檬酸三丁酯(acetyltributyl citrate, ATBC)。在微波器皿方面,發現橄欖油及蒸餾水與PS接觸加熱後,可檢測出苯乙烯單體及苯及烷之存在。至於與PE保鮮膜及PP容器加熱後皆未發現有塑化劑或苯環衍生物之遷移。 |
英文摘要 | Microwaveable plastic films, made of polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) and ployethylene (PE); microwaveable containers, made of poystyrene (PS) and ploypropylene (PP), were allowed to contact with low fatty food simulant-water, and high fatty food simulant-olive oil, then heated in a microwave oven. The heated food simulants were extracted with ether or methanol, and the extracted solution analyzed by gas chromatography and mass spectrometry. The plasticizer of dioctyl phthalate (DOP) was found in olive oil and water, respectively, that were in contact with PVC film, acetyltributyl citrate (ATBC) was detectable in olive oil that place in PVDC film. In microwaveable containers, both of styrene monomer and ethylbenzene were found in olive oil and water, respectively, that were in contact with PS containers, no plasticizer or benzene derviatives were detected in either olive oil or water that were in contact with PE films and PP containers, respectively. |
