size and 50 m2/g) of 0.3 g/100 ml was used.
- The initial concentration of anilines was 1E-04 mol/l.

Concentration :
Method : GC quantification, MS identification
Result : Toluidine (isomers not specified, but o-toluidine likely to be present) occurs
in vegetables like kale (Brassica oleracea), celery (Apium graveolens), and
carrots (Daucus carota ). In beans (Phaseolus vulgaris), o-toluidine was
detected but could not be quantitatively determined with a determination
limit of 0.1 mg/kg fruit.
Test condition : - About 20 vegetables, coffee, and several other food products were
examined
- GC quantification after derivatisation with trifluoroacetic acid anhydride
- MS identification
- Determination limit depending on sample clean-up, e.g. 0.1 mg otoluidine/kg
fruit
