| 中文摘要: |
| 目的 建立食品接触材料中32种添加剂迁移量的高效液相色谱检测方法，调查市售塑料食品接触材料中32种添加剂的迁移水平。方法 选取103批不同材质的塑料食品接触材料，采用异辛烷、乙醇（体积分数分别为50%，20%，10%）、质量分数为3%的乙酸浸泡样品，得到模拟液，用液相色谱仪分析，外标法定量。结果 DBP，DEHP，二苯酮，UV-1577，BHT，697，2246，BHEB和荧光增白剂184均有检出，其中11批PVC样品中DBP或DEHP、1批PP样品中二苯酮和1批PC样品中UV-1577的迁移量高于限量要求。上述添加剂在异辛烷模拟物中的检出率最高，在体积分数为50%的乙醇模拟物中有较低的检出率，在其他3种模拟物中均未检出。结论 塑料食品接触材料不宜直接用于接触油类食品和浓度较高的酒类食品。PP材质中的二苯酮、PC材质中的UV-1577、PVC材质中的DBP和DEHP存在的潜在危害较大，应加强监管。 |

| To established an analytical method for determination of the migration amount of 32 additives in food contact materials by high performance liquid chromatography, and investigate the migration levels of 32 additives in plastic food contact materials sold in market. Samples selected from 103 batches of plastic food contact materials of different textures were soaked by isooctane, 50% ethanol, 20% ethanol, 10% ethanol, 3% acetic acid to obtain simulants. They were analyzed by HPLC, and quantitated by external standard method. DBP, DEHP, benzophenone, UV-1577, antioxidant BHT, 697, 2246, BHEB and fluorescent brightener 184 were detected and qualified. The migration amount of DBP or DEHP in 11 batches of PVC, benzophenone in 1 batch of PP, and UV-1577 in 1 batch of PC materials exceeded the standard limit. The above additives had the highest detection rate in isooctane and had a lower detection rate in 50% ethanol and were not detected in the other three simulants. Plastic food contact materials should not be used directly for contact with oil and high concentrations of alcoholic food. There was a potential risk of benzophenone in PP materials, UV-1577 in PC materials, DBP and DEHP in PVC materials. Regulation and monitoring on these additives in plastic food contact materials should be strengthened. |
