中文摘要:
      目的 介绍聚苯乙烯包装材料中苯乙烯单体检测及迁移的研究进展。方法 总结国内外聚苯乙烯中苯乙烯检测及迁移的文献,并将国际上苯乙烯最新的检测方法和迁移研究和我国的进行对比,指出我国在该方面的不足和发展方向。结果 溶解-沉淀可以有效地提取聚苯乙烯中的苯乙烯,其回收率达到86%以上。苯乙烯不易向蒸馏水中发生迁移,只有在较高温度和较长时间下才有少量迁移。不同迁移方式对苯乙烯的迁移影响较大,由于切口的存在使得全浸泡的迁移量高于单面迁移。结论 溶解-沉淀是提取苯乙烯的有效方法,不同食品模拟物、温度、时间以及迁移方式都会对苯乙烯的迁移产生影响,应避免聚苯乙烯在较高温度、较长时间的情况下接触食品,且不使用表面已损坏的聚苯乙烯包装材料,以减少其对人体的危害。
英文摘要:
      The work aims to introduce the research progress on detection and migration of styrene in polystyrene packaging materials. Domestic and overseas literatures related to the detection and migration of styrene in polystyrene were summarized; meanwhile, the newest international detection method and migration researches on styrene were compared with those in China, which showed the shortage and development direction of the researches concerned. In the method of dissolution-precipitation, the styrene could be extracted from polystyrene efficiently, and the recovery of this method was more than 86%. It was not easy for styrene to migrate into distilled water. Only a small amount of styrene could migrate at higher temperature and in a longer period. Various migration ways could affect the migration of styrene greatly, and the fully immersed migration amount was higher than the single-sided migration due to the existence of cuts. Dissolution-precipitation is an effective method to extract styrene. Different food simulants, temperatures, time and migration ways can affect the migration of styrene. The polystyrene should not contact the food at high temperatures and in a longer period; in addition, the polystyrene packaging materials with damaged surface should not be used, so that the harm to human body can be reduced.
