Residues of five pesticides(chlorpyrifos, chlorfenapyr, cyhalothrin, cypermethrin,
tebuconazole) commonly found in paste and sauce containing hot pepper, were analyzed
by gas chromatograph？electron capture detector(GC-ECD) and gas chromatograph？
nitrogen phosphorous detector(GC-NPD) techniques, using a multi-residue method. LODs
for hot pepper paste and chili sauce were 0.005~0.03 mg/kg and 0.0007~0.009 mg/kg,
respectively. The corresponding LOQs were 0.02~0.07 mg/kg and 0.002~0.03 mg/kg. Of
the 109 commercial samples analyzed, the pesticides chlorfenapyr, cypermethrin, and
chlorpyrifos were present in only 4 of the chili sauces; and their concentrations were
within the range 0.003 to 0.088 mg/kg. Method efficiency was examined by addition of
each pesticide at concentrations of 0.01 mg/kg (0.04 mg/kg for tebuconazole), 0.1 mg/kg,
and 1.0 mg/kg. Recoveries for hot pepper paste and chili sauce were 66.8~139.8% and
65.2~110.0%, respectively.
