| 摘 要： | 探讨了米糠油精炼过程中,运用双乙醇胺同步完成脱胶和脱酸的工艺。重点研究了双乙醇胺用量、反应时间、反应温度等操作条件对米糠油脱胶脱酸效果的影响,通过单因素和正交试验得出以下结论:双乙醇胺加量为油质量的3.0%,反应时间60min,反应温度30℃,所得米糠油酸值从18.4mg/g(KOH)降至1.5mg/g(KOH)以下,磷质量分数从681mg/kg降至7mg/kg以下。脱胶脱酸米糠油谷维素含量为毛油谷维素含量的75%以上,同时油的色泽明显得到改善。

| Abstract: | It is discussed in this paper the technology of synchronous degumming and deacidification of rice bran oil by diethanol amine.The experiment is focused on the effects of the content of diethanolamine,the reaction time and the reaction temperature to the process of degumming and deacidification of rice bran oil.Through single factor and orthogonal experiment,a conclution is obtained that diethanolamine dosage 3.0% weight of the oil,reaction time 60 min and reaction temperature 30℃.The acid value and phosphorus content of the oil are decreased to less than 1.5 mg/g (KOH) and 7 mg/kg respectively. More than 75% oryzanol of the crude oil is retained after reaction,and the colour of the oil is evidently improved. |
