对中国所采集的4种食用油(橄榄油、花生油、厨房抽油烟机油和油炸摊位油)中16种多环芳烃(PAHs)进行了检测。多环芳烃经正己烷和N，N-二甲基甲酰胺液-液萃取后，经Folorisil固相萃取柱净化后送入GC-MS测定。花生油样品中多环芳烃的平均浓度为0.82mU/kg，橄榄油样品中的平均浓度为457.12微克/千克。重多环芳烃的平均浓度(n=3)为花生油样品中苯并[a]芘的0.68 mU g/kg和橄榄油样品中的苯并[b]荧菲16.35 mU g/kg。数据分析表明，不同浓度的多环芳烃可用于植物油的质量鉴别。需要对中国提供的食用植物油中的多环芳烃水平进行大规模调查。(C)2012爱思唯尔有限公司。保留所有权利。
Concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) were measured in four edible oils collected in China (olive oil, peanut oil, oil collected from a kitchen range hood, and oil from a fried food stall). The PAHs were liquid-liquid extracted with n-hexane and N,N-dimethylformamide, then passed through a florisil solid phase extraction cartridge for clean-up, and submitted to GC-MS for determination. The mean concentration (n = 3) of light PAHs ranged from 0.82 mu g/kg for chrysene (peanut oil sample) to 457.12 mu g/kg for acenaphthylene (olive oil sample). For heavy PAHs, the mean concentration (n = 3) ranged from 0.68 mu g/kg for benzo[a]pyrene in the peanut oil sample to 16.35 mu g/kg for benzo[b]fluoranthene in the olive oil sample. Data analysis suggested that the concentrations of different PAHs could be used for quality discrimination of vegetable oils. A large-scale investigation on the level of PAHs in edible vegetable oils available in China is required. (C) 2012 Elsevier Ltd. All rights reserved.
