ESBO is transesterified with methoxide/methanol directly in the homogenated food, i.e. without prior extraction, and analyzed on a cyanopropyl or phenyl polysiloxane stationary phase without formation of dioxolanes. For most foods, flame ionization detection (FID) was appropriate, but for samples with interfering components, GC-MS was needed. Chemical ionization (CI) with ammonia is more sensitive and more selective than electron impact ionization (EI). In CI, positive and negative ion monitoring (PCI and NCI) are similar in sensitivity, but different in selectivity, i.e. the combination of the two is well suited for confirmation. Results are shown to be in agreement with on-line LC-GC-FID.
