摘  要：
利用气相色谱模拟分离软件,测定火腿肠及其肠衣中的塑化剂邻苯二甲酸二甲酯、邻苯二甲酸二乙酯、邻苯二甲酸二丁酯、邻苯二甲酸二环己酯、邻苯二甲酸二(2-乙基)己酯和邻苯二甲酸二正辛酯的含量。对比超声提取和索式提取2种前处理方法对样品中塑化剂的提取效果,确定了程序升温条件,采用外标法定量。结果表明:6种标准物质的标准曲线R~2为0.996 7~0.998 8,最小检出限为0.04 mg/kg,相对标准偏差为5.0%~9.3%;索式提取法的提取效果更显著,某些火腿肠和火腿肠肠衣中含有高含量的生殖致癌物邻苯二甲酸酯类物质。

摘  要：
Gas chromatography separation simulation software was used to determine the contents of the plasticizers dimethyl phthalate(DMP), diethyl phthalate(DEP), dibutyl phthalate(DBP), dicyclohexyl phthalate(DCHP), bis(2-ethylhexyl) phthalate(DEHP) and di-n-octyl phthalate(DNOP) in sausage and casing. Ultrasonic-assisted extraction and Soxhlet extraction were compared for their efficiencies in the extraction of plasticizers. The optimum temperature programming condition was established. The plasticizers were quantified by the external standard method. Overall, the correlation coefficients for six plasticizers were 0.996 7–0.998 8, and the lowest detection limits was 0.04 mg/kg. The precision expressed as relative standard deviation was 5.0%–9.3%. Soxhlet extraction showed higher extraction efficiency than ultrasonic-assisted extraction. Some samples of sausage and casing were found to contain significant amounts of carcinogenic phthalates.
