| 目的 建立测定1,4-丁二醇的气相色谱检测方法，确认食品接触材料及制品中1，4-丁二醇迁移量是否满足国标限量要求。方法 对可降解塑料产品进行迁移试验，采用气相色谱法对迁移液中1,4-丁二醇进行分离、定性和定量检测。结果 该法对1,4-丁二醇迁移量的方法检出限为0.4 mg/kg，1,4-丁二醇的含量为0～10 mg/kg时，与色谱峰面积具有良好的线性关系，相关系数大于0.995，样品加标回收率为95.2%～108.7%，测定结果的相对标准偏差为5.9%～9.7%(n=10)。结论 该方法适用于食品接触材料及制品1,4-丁二醇迁移量的检测。 |
| 英文摘要: |
| To establish a gas chromatographic method for the determination of 1, 4-butanediol migration,to confirm whether the migration amount of 1, 4-butanediol in food contact materials and products meets the national standard limit requirements. The migration test was carried out on the degradable plastic products, and the 1, 4-butanediol in the migration solution was separated, qualitatively and quantitatively determined by gas chromatography. The detection limit of this method was 0.4 mg/kg, and the concentration of 1, 4-butanediol has a good linear relationship with the chromatographic peak area in the range of 0~10 mg/kg, with a correlation coefficient more than 0.995 and a spike recovery for the sample between 95.2% and 108.7%. The relative standard deviation of the determination results was between 5.9% and 9.7% (n=10). This method is suitable for the detection of 1, 4-butanediol migration of food contact materials and products. |
