Results are reported for the fourth interlaboratory study organized by the Commission of the European Communities for the adoption of an official method for determining the total migration of plastic materials in liquids simulating fatty foodstuffs. In each method, a sample of plastic material was weighed before and after it was placed in contact with fatty simulants. The fat absorbed by the sample, extracted or dissolved by suitable solvents, was determined by gas chromatography or radiometry. The results obtained confirm the conclusions given previously. Each method was moderately satisfactory, but less so between laboratories.
本文报道了由欧洲共同体委员会组织的第四次实验室间研究结果,该研究旨在通过一种官方方法来测定塑料材料在模拟含脂食品的液体中的总迁移量。在每种方法中,塑料材料样品在与含脂模拟物接触前后均进行称重。通过气相色谱法或放射性测量法测定样品吸收、经合适溶剂萃取或溶解的脂肪量。所获结果证实了先前给出的结论。每种方法都还算令人满意,但各实验室之间的结果差异较大。
