摘要
用提纯、酸化、活化后的凹凸棒黏土吸附大麻籽油中的色素,采用正交实验确定脱色的最优工艺条件为:凹土用量6 g/100 mL油,吸附时间40 min,凹土活化温度300℃,吸附温度35℃时脱色效果最好,脱色率可达94.31%。
The attapulgite clay treated by purification,acidification and activation was used to remove the pigments in the hemp seed oil. By orthogonal experiment,the best parameters were obtained:the activated temperature of attapulgite clay 300 ℃,clay dosage 6 g activated attapulgite clay per 100 mL oil, adsorption time 40 min, adsorption temperature 35 ℃. Under these conditions,the bleaching rate was 94.31%.
