It is worth mentioning that sample 1 was a semi-processed
frozen product, which may require shorter frying time and lower
frying temperature. Therefore, among the eight commercial youtiao
samples, the lowest concentrations of BaP (0.75 mg/kg), PAH8
(8.72 mg/kg), total PAHs (27.30 mg/kg) and BaPeq (1.51 mg/kg) were
all detected in sample 1. By the same token, both the two lab-made
samples had mean concentrations of BaP, PAH4, PAH8 and total
PAHs relatively lower than that of the commercially availablesamples. Kao, Chen, Chen, Huang, and Chen (2012) also found a
larger amount of total PAHs (79.7 mg/kg) in duck drumstick fried for
15 min, comparing to chicken drumstick (54.8 mg/kg) fried for
12 min, due to the longer frying time of the former.
