摘 要:多環(huán)芳烴是最為常見的污染物之一,是一種能夠致突變、致癌的化合物,世衛(wèi)組織將苯并芘列為同一類對(duì)人類有害且致癌的物質(zhì)。所以,相關(guān)單位對(duì)食品中潛在的多環(huán)芳烴的含量監(jiān)測(cè)需要十分精準(zhǔn)。本文主要分析了超臨界流體萃取、微波輔助萃取、超聲波萃取以及索氏萃取等多種提取方法,并系統(tǒng)地介紹了氣相色譜-質(zhì)譜、氣相色譜、高效液相色譜等多種檢測(cè)方法。

Abstract: Polycyclic aromatic hydrocarbons are one of the most common pollutants and are compounds that can cause mutations and cause cancer. The WHO lists benzopyrene as the same class of substances that are harmful and carcinogenic to humans. Therefore, the relevant units need to monitor the content of potential PAH hydrocarbons in food. In this paper, ultrasonic and cable extraction, and various detection methods including gas chromatography-mass spectrometry, gas chromatography, high performance liquid chromatography and so on.
Keywords: polycyclic aromatic hydrocarbons; detection method; research and analysis
多環(huán)芳烴(Polycyclic Aromatic Hxydrocarbons,PAHs)是一種廣泛存在于環(huán)境、食品加工等區(qū)域的污染物之一,也是人類所發(fā)現(xiàn)的最早的具有導(dǎo)致畸形、引起癌變、導(dǎo)致突變效應(yīng)的、具備長(zhǎng)期惡性作用的有機(jī)污染物之一。在眾多多環(huán)芳烴中,最常見且最容易引發(fā)癌變的便是具備4~6個(gè)苯環(huán)的化合物。就一般情況而言,有機(jī)物的不完全燃燒與熱解會(huì)生成多環(huán)芳烴;天然火災(zāi)、化石燃料、火山噴發(fā)等也會(huì)產(chǎn)生一定濃度的多環(huán)芳烴;人為因素主要有礦物燃燒、紙張燃燒、木材燃燒等過程的不完全燃燒。食品中殘留的多環(huán)芳烴是在食品加工過程中產(chǎn)生的污染及環(huán)境的污染造成的。本文的研究能夠有效強(qiáng)化在食品中提取多環(huán)芳烴的措施與手段,且對(duì)其后續(xù)的綜合性發(fā)展具備一定的指導(dǎo)性意義,對(duì)于該種污染物的含量檢測(cè)具備現(xiàn)實(shí)性意義[1]。
