摘　　要：氢化过程中的高温、高压、催化条件将产生大量的反式脂肪酸(trans fatty acids,TFA),且不同氢化植物油中反式脂肪酸的含量因加工工艺的不同而有很大差异,国内外众多研究都致力于寻求在氢化过程中减少TFA生成量的方法。本文对目前国内外各类催化剂在油脂加氢反应中的脂肪酸选择性进行综述讨论,重点介绍食品工业中常使用的镍基催化剂,铜、金和铂族贵金属等非均相催化剂以及均相催化剂、非晶态催化剂的新型催化剂。The high temperature,high hydrogen pressure and catalytic conditions of hydrogenation process will favor the formation of trans fatty acid(TFA).The content of TFA in hydrogenated oils differs from the processing technology.Many researchers had sought for the methods to reduce the formation of TFA in the hydrogenation.The effect of various kinds of hydrogenation catalysts on fatty acid selective in edible oil hydrogenation was discussed in the paper.The catalysts used in hydrogenation industry including nickel,copper,gold,platinum group metals heterogeneous catalyst,the homogeneous catalyst,and amorphous catalyst are briefly introduced.
