摘要
本文探讨了用70%和80%乙醇的已烷液(v/v)作为萃取剂,对酸值为28.60%的米糠混合油进行多级错流和逆流液—液萃取脱酸研究.分析讨论了脂肪酸萃取因子与脂肪酸含量、萃取溶剂比(即:萃取剂/混合油)的关系以及理论级数与脂肪酸萃余率、萃取剂的乙醇体积浓度与萃取效果等之间的关系,为工业化生产提供参考.
Deacidification of rice bran miscella with 70% and 80% ethanol-hexane(v/v) by multi-stage cross-and counter-current liquid-liquid extraction was studied. Particular analyses were made into the relationships not only between the extraction factor and the percentage of fattty acid,between the factor and the ratio of solvent to miscella,but also between the the oretical base and the percentage of non-extracted fatty acid, between the volume concentration of ethanol in solvent and the refined result.
