Development and validation of gas chromatography-mass spectrometric method for the determination of epoxidized soybean oil in foods stored in glass jars with metal lids
A method has been developed for the determination of epoxidized soybean oil (ESBO) in oily foods stored in glass jars with metal lids using gas chromatography-mass spectrometry (GC-MS). ESBO and its internal standard (cis,cis-11,12;14,15-diepoxyeicosanoate) were isolated from the matrix by transeste...

A method has been developed for the determination of epoxidized soybean oil (ESBO) in oily foods stored in glass jars with metal lids using gas chromatography-mass spectrometry (GC-MS).
