摘　　要：食用油净化处理中,吸附法因其在脱除效果、生产成本和实际生产可操作性方面的独特优势,是目前消减多环芳烃最为有效的方法。对食用油脂中多环芳烃进行了概述,重点从吸附作用机理、吸附过程的影响因素及吸附剂的类型等方面,综述了吸附技术在食用油中的多环芳烃脱除领域的研究进展和发展趋势;比较了常见的几种吸附剂的优缺点;对吸附法脱除多环芳烃的发展方向进行了展望,为开发更高效的吸附剂提供了研究思路。吸附脱除多环芳烃的同时,会造成油脂中中性油、微量营养成分及风味的严重损失。未来可以结合吸附作用机制,开发新型专用吸附剂或者对现有吸附剂进行表面改性,以期得到更高品质的食用油。Among the edible oil purifying technologies,the adsorption process is the most effective method for reducing polycyclic aromatic hydrocarbons(PAHs)because of its high efficiency,low production cost and actual production operability.The paper provides an overview of PAHs in edible oil,focusing on the adsorption mechanism,effect factors and types of adsorbents,etc.The research progress and development trend of adsorption technology in the field of PAHs removal from edible oils were reviewed;the advantages and disadvantages of several common adsorbents were compared;meanwhile,the development of the adsorption method for PAHs removal was prospected,which gave some research ideas for the development of more efficient adsorbents.The adsorption to remove PAHs can cause severe loss of neutral oil,trace nutrients and oil flavor.In the future,new special adsorbents or surface modifications of existing adsorbents can be developed in conjunction with the adsorption mechanism to obtain higher-quality edible oils.
