    Journal: J AOAC Int; 2000; 83(4):929-32. PubMed ID: 10995117.
    Abstract:
    A headspace gas chromatographic (GC) method was developed to determine 1,3-butadiene (1,3-BD) in simulated saliva in contact with chewing gum. The calibration graph was linear, and the limit of detection was 0.004 mg/L, which is well below the migration limit for this substance. The headspace GC method provides rapid and reliable analysis for monitoring 1,3-BD migration from chewing gum into simulated saliva. In this paper, we report headspace methodology for sensitive determination of 1,3-BD in chewing gum and results of selected analyses, enabling preliminary assessment of possible exposure to 1,3-BD through migration.
