摘要
在国内茶油的脱色工艺一般为传统的白土脱色,所得油色泽一般为黄色,仅符合一般食用油的要求而难以满足化妆品用油的要求,而且白土脱色工艺中产生的废弃物、废水对环境污染大。本文针对这一情况,采用了一种新型的方法即硅胶柱层析法脱除茶油中的色素,得到了清亮透明无色的茶油并将茶油中油酸的含量提高到了83.63%。
The traditional bleaching method, namely using active clay, was used in the bleaching technique at home. But the product was yellow, high acid value and only used as a kind of edible oil not as a kind of cosmetic oil. In addition, using traditional bleaching technique there were so many wastes and environmental pollutants. According to this situation, a new method namely used silica gem columniation was researched, the clear and colorless tea seed oil was attained and the content of oleic acid was up to 83.36%.
