摘　　要：目的:传统的脱色方法很难使茶油达到化妆品和医药用油的色泽要求,采用生物酶脱胶、膜技术、碱脱酸、吸附脱色等方法综合处理,使茶油精炼后达到无色。方法:用中心组合设计优化吸附脱色的工艺条件。结果:最佳脱色工艺条件为:反应温度87℃,吸附剂用量2.7%,反应时间30min,茶油脱色率为90.22%。结论:经上述方法综合处理后所得茶油色泽为R0Y0(25.4mm比色槽),达到化妆品和医药用茶油的要求。The color of medical camellia oil and cosmetic camellia oil was prescribed with colorless, it was hard to receive for traditional method. Comprehensive method concluding biological enzyme degumming, membrane technology, alkali deacidification, adsorbent decolouring were carried on camellia oil. Technology condition of adsorbent decolouring was optimized by central combination design method, it＇s optimum condition was： reaction temperature 87 ℃, dosage of absorbent 2.7%, reaction time 30 min, decolouring rate was 90.22%. After comprehensive treatment by above method, the camellia oil was up to the standard of medical camellia oil and cosmetic camellia oil, with color value ROYO（25.4 nm slot）.
