| 目的 研究体积分数为50%的乙醇作为食品接触用橡胶材料及制品的油脂类食品模拟物的适用性，为我国食品接触用橡胶材料及制品标准的修订提供数据支撑。方法 制备含1,4-二苯基-1,3-丁二烯(1,4-diphenyl-1,3-butadiene, DPBD)的阳性橡胶样片，通过迁移实验并结合气相色谱-三重四极杆串联质谱法，测定并比较DPBD在不同的迁移条件下在含油脂真实食品、食品模拟物(体积分数50%的乙醇、植物油)和替代溶剂(体积分数95%的乙醇)中的迁移量。结果 同一个迁移条件下，DPBD在体积分数50%的乙醇中校正前的迁移量大于在火腿肠和午餐肉中的真实迁移量，其在橄榄油校正前的迁移量均大于在对应的4种含油脂食品中的真实迁移量;丁腈橡胶中DPBD在替代溶剂(体积分数95%的乙醇)的迁移量大于在橄榄油的迁移量。结论 对于含油脂食品，现行食品接触用橡胶材料及制品标准中对油脂类食品模拟物(体积分数50%的乙醇)的设定并不完全适用;建议首选橄榄油作为油脂类食品模拟物，当接触食品为火锅底料或者黄油时不建议对结果进行校正，当接触食品为火腿肠或午餐肉时建议对结果进行校正，或选择体积分数50%的乙醇且不对结果进行校正;对于食品接触用丁腈橡胶，可以采用体积分数95%的乙醇作为油脂类食品模拟物的替代溶剂，对乙丙橡胶不建议采用体积分数95%的乙醇作为替代溶剂。 |

| The purpose is to study the applicability of 50% ethanol as the fatty food simulant for food contact rubber. And the results of this study provide data support for the revision of the standard of food contact rubber in China. This paper took the positive rubber samples containing 1,4-diphenyl-1,3-butadiene (DPBD) as the research object. The migration of DPBD from the positive rubber samples to real foods, food simulants (50% ethanol and olive oil) and substitute solvent (95% ethanol) were respectively determined and compared by gas chromatograph-triple quadrupole tandem mass spectrometry (GC-MS/MS). Under the same migration condition, DPBD migration in different simulants and foods showed the rules of 50% ethanol＞ham sausage or luncheon meat and olive oil＞four kinds of foods. For nitrile butadiene rubber (NBR), the migration of DPBD in 95% ethanol was higher than that in olive oil. The results showed that the setting of fatty food simulant (50% ethanol) was not completely applicable in the current standard of food contact rubber. It is recommended to select olive oil as the fatty food simulant. It is not recommended to correct the results of olive oil while the rubber comes into contact with hotpot condiment or butter. It is recommended to correct the results of olive oil while the rubber comes into contact with ham sausage or luncheon meat. It is not recommended to correct the results of 50% ethanol solution while the rubber comes into contact with ham sausage or luncheon meat. 95% ethanol can be used as the substitute solvent for nitrile butadiene rubber (NBR), but it is not recommended for ethylene propylene diene monomer rubber (EPDM). |
