摘　　要：[目的]优化从酒糟中提取菲汀的最佳工艺条件。[方法]通过正交试验及单因素试验考察酸浓度、酸浸时间、浸提温度、振荡条件、浸提酸种类、中和剂种类对酒槽中菲汀提取效果的影响。[结果]试验得出的最佳工艺条件:采用酸浓度0.8%,酸浸时间6 h,浸提温度60℃,盐酸间歇振荡,混合中和剂碱石灰(10%)、Na HCO3(10%)和Na OH(1 mol/L)中和,碱沉条件,p H为6.5。[结论]研究改善了现有的菲汀提取工艺条件,利用废弃的原料来增加燃料乙醇发酵副产物的附加值,使燃料乙醇企业能够良性运转,并可解决国内外对菲汀的需求问题。[ Objective ] The optimum condition of extracting phytin from distiller＇ s grains were studied. [ Method ] The effects of acid concentration, acid leaching time, extraction temperature, the oscillation condition, the leaching of acid type, neutralization agent type on extracting phytin from distiller＇ s grains were determined by single factor test and orthogonal test. [ Result ] The optimum process conditions ： using acid concentration 0.8% , acid leaching time 6 h, extraction temperature 60℃, hydrochloric acid intermittent oscillation, mixed alkali lime neutralization agent soda lime （ 10% ）, NaHCO3 （ 10% ） and NaOH （ 1 mol/L）, alkali precipitation conditions 6.5 pH. [ Conclusion] The study can improve current extraction conditions for phytin. Use the abandon raw materials increase attachment value of the fuel ethyl alcohol fermentation by-product, make sure the fuel ethyl alcohol enterprise can revolute in a benigning type, and resolve the demand of the enterprises all over the world.
