中文摘要:

      目的 研究全浸没法、袋装法、测试池法和填充法四种不同的浸泡方式对各种食品接触材料高锰酸钾消耗量的影响。方法 测试方法参照GB/T 5009.60-2003《食品包装用聚乙烯、聚苯乙烯、聚丙烯成型品卫生标准的分析方法》中测定高锰酸钾消耗量的方法。结果 密胺餐具采用填充法比全浸没法和测试池法所消耗的高锰酸钾量高。复合膜产品采用全浸没法所消耗的高锰酸钾量是袋装法的2倍多。纸浆类产品采用填充法所消耗的高锰酸钾量比全浸没法所消耗的高锰酸钾量大。结论 扁平容器类餐具适合采用测试池法; 容积较小的容器餐具类适合采用全浸没法; 薄膜/袋包装类产品适合采用袋装法和全浸没法, 其中复合薄膜类产品适合袋装法, 纸浆类产品则适合全浸没法。

英文摘要:

      Objective To investigate the effects of different soaking methods such as total immersion, cell, pouch and article filling on potassium permanganate consumption in food contact materials. Methods The test method was established according to GB/T 5009.60-2003, “polyethylene, polystyrene, polypropylene moldings hygiene standards for food packaging analysis method”. Results The PPC of melamine tableware by article filling was higher than that by total immersion. The PPC of composite film products using total immersion was 2 times higher than that using a pouch. The PPC of paper-pulp products by article filling was higher than that by total immersion. Conclusion While cell was suitable for flat tableware, total immersion was more appropriate for tableware with smaller volume. Pouch or total immersion should be used for film or pouch packaged products, in which the composite film should use a pouch, and total immersion is suitable for paper-pulp products.
