| 摘 要： | 采用活性白土、自制的脱胶白土及碱性白土对菜籽油进行干法同时脱色、脱胶、脱酸耦合精炼研究.结果表明:50.00 g毛油加热到70℃后,先加入2.0％活性白土脱色10 min,再加入2.0％脱胶白土,10 min后加入3.0％碱性白土,搅拌反应95 min后离心得到脱色率超过90％、磷含量小于5 mg/kg、酸值(KOH)小于0.2 mg/g的精炼菜籽油,达到传统精炼工艺的油品质量要求.该油脂精炼工艺过程及设备简单、生产效率高、无废水排放,具有良好的应用前景.

| Abstract: | The activated clay,self-made alkaline clay and degumming clay were used to study a dry-coupled refining process of rapeseed oil including deacidification,decolorization and degumming.The results showed when 50.00 g crude oil was heated to 70 ℃,first,2.0% activated clay was added to the oil to decolor 10 min;second,2.0% degumming clay was added to the oil to degum for 10 min;then 3.0% alkaline clay was added to the oil and stired for 95 min.After centrifuging,the refined oil was obtained,and the bleaching rate was more than 90%,the phosphorus content was less than 5 mg/kg,and acid value was less than 0.2 mgKOH/g,the parameters of refined oil reached the quality standard of traditional refining.The process was simple,high efficiency,and had no sewage discharge,so it would have a good application prospect. |
