摘要
中国南方几省茶油有一定产量，而国外茶油产量极小，基本上没有市场。利用茶油的特殊结构进行酶促改性制类可可脂很少见有报道。选择１，３位定向脂肪酶，在茶油、硬脂酸、软脂酸混合非水溶剂（己烷）体系中进行一步酯交换反应，最终制出了类似可可脂结构和组成的代用品。本研究主要对茶油酶促改性的主要影响因素进行了探讨。
Teaseed oil possesses commercial values only in China and is mainly produced in the south part of Chian. Using teaseed oil to produce cocoa butter equivalent by lipasecatalyzed interesterification has rarely been reported. In this paper,the acidlysis reactions between teaseed oil and stearic acid with palmitic acid via 1,3-specific lipase in a nonaqueous solvent system are carried out,The results show that the fatty acid compostition and triglyceride structure of the products are very similar to natural cocoa butter. And key factors affecting the interesterification process are systematically researched
