目的研究硅酸镁在油茶籽油简炼工艺中的应用。方法采集需精炼的原油为研究对象,添加其质量的1.5%和3.0%硅酸镁搅拌混合,再加入0.2‰的水,抽真空条件下升温到110~120℃, 10 min后冷却,过滤并测试试样色泽、酸价、过氧化值和苯并(a)芘等品质指标。结果经过硅酸镁处理的试样,其理化和食品安全指标均符合油茶籽油国家标准要求。结论利用硅酸镁强吸附特性在适宜条件下可简化油茶籽油精炼工艺,达到降本减耗、安全达标的炼油效果。

Study on the application effect of magnesium silicate in the refining process of Camellia oil

Objective To study the application of magnesium silicate in Camellia oil refining process. Methods The crude oil to be refined was collected as the research object, 1.5% and 3.0% of its mass magnesium silicate was added to stir and mix, and then 0.2‰ of water was added. The temperature was raised to 110-120 ℃ under the condition of vacuum pumping, and the temperature was cooled after 10 min. After filtered, the color, acid value, peroxide value, benzo(a) pyrene and other quality indexes of the sample were tested. Results The physicochemical and food safety indexes of the samples treated with magnesium silicate met the requirements of national standards for Camellia oil. Conclusion The refining process of Camellia oil can be simplified by using strong adsorption of magnesium silicate under suitable conditions, which can achieve the refining effect of reducing cost and consumption and reaching the safety standard.
