利用气相色谱及气相色谱-质谱联用技术,对食品中4种邻苯酸二甲酯类化合物进行检测。对于非油脂类食品,气相色谱法的检出限为1.5mg/kg,平均回收率为67.4%-92.9%,相对标准偏差为1.6%-4.7%;气相色谱-质谱联用的检出限为0.05mg/kg,平均回收率为66.3%-112.9%,相对标准偏差为2.9%-11.3%。对于油脂类食品,气相色谱法的检出限为30mg/kg,平均回收率为73.4%-96.1%,相对标准偏差为1.6%-2.8%;气相色谱-质谱联用的检出限为1.5mg/kg,平均回收率为64.1%-80.2%,相对标准偏差为1.6%-4.5%。用该分析方法对285批食品样品进行了分析检测,1批食品样品检出BBP,13批检出DBP,63批检出DEHP,总检出阳性样品68批,总阳性检出率23.9%,其检出质量分数为0.05-1.27mg/kg。该方法前处理简单,分离效果好,灵敏度高,能够满足食品中4种邻苯二甲酸酯检测的需要。

In this paper,4 phthalates(DBP,BBP,DEHP,DNOP) in the foods were determined by gas chromatography and gas chromatography-mass spectrometry.In the fat free foods with gas chromatography,the method detection limits was 1.5mg/kg,the recoveries ranged from 67.4%-92.9%,and the relative standard deviations were between 1.6% and 4.7%;with gas chromatography-mass spectrometry,the method detection limits was 0.05mg/kg,the recoveries ranged from 66.3%-112.9%,and the relative standard deviations were between 2.9% and 11.3%.In the greasy foods with gas chromatography,the method detection limits was 30mg/kg,the recoveries ranged from 73.4%-96.1%,and the relative standard deviations were between 1.6% and 2.8%;with gas chromatography-mass spectrometry,the method detection limits was 1.5mg/kg,the recoveries ranged from 64.1%-80.2%,and the relative standard deviations were between 1.6% and 4.5%.Altogether 285 pieces of food samples were detected by this method.The findings were as follows: 1 sample contained BBP,13 samples contained DBP,and 63 samples contained DEHP.The total 68 samples showed positive results,and the total detectable rate of phthalates was 23.9%,and the concentrations of phthalates were from 0.05 mg/kg to 1.27 mg/kg.Results showed that the method was simple,rapid and had a good separation effect and high sensitivity.So it can meet the demand for the determination of 4 phthalates in the various foods.
