Abstract 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.
