Optimization of Residual Hexane in Edible Oils Analysis Using Static Headspace Gas Chromatography

Table 3

Comparison of results of residual hexane in different edible oils.

Edible oils	Residual hexane concentration (mg kg^−1)
	AOCS official method with higher standard calibration concentration (0–938 mg kg^−1)	Modified AOCS official method with lower standard calibration concentration (0–68 mg kg^−1)
Sunflower oil	3.074	2.688^a
Corn oil	0.414	0.358^a
Sesame oil	0.711	0.602^a
Palm oil	0.144	0.126^a
