| 中文摘要: |
| 油脂氢化是油脂工业重要的反应过程,在此过程中油脂的结构和组成发生改变,在部分氢化过程中不可避免地产生反式脂肪酸.鉴于反式脂肪酸对人体健康有害,目前关于催化剂的研究大多集中在如何控制反式脂肪酸的生成量方面.就各种催化剂对食用油氢化反应的异构化影响进行讨论,重点介绍食品工业中使用的镍及其他诸如铜、金和铂族金属等非均相催化剂对反式脂肪酸生成量的影响,对非均相催化剂及与催化剂相关的载体、处理方法等诸种因素对顺式选择性的影响进行了简单阐述. |
| 英文摘要: |
| Hydrogenation of edible oil is an important reaction in oil and fat industry,in which the composition and structure of edible oil are changed,and trans fatty acid is formed inevitably in partial hydrogenation.Since trans fatty acid is noted for its harmfulness to human health,recent study on hydrogenation has been focused on how to control the amount of trans fatty acid.The effect of various kinds of hydrogenation catalysts on fatty acid isomerization in edible oil hydrogenation was discussed,and the effect... |
