    • Anhydrous methods of fractionating corn grain that do not require the use of water but rather depends on use of organic solvents are described. The methods include contacting whole grain corn flour with a at least one organic solvent selected from the group consisting of a C1-C6 alcohol, ketone, ester or furan to form an admixture having no more than 15% w/w water. The admixture is separated into i) a solids fraction enriched with corn fiber and protein and 2) a liquid organic slurry comprising suspended starch, dissolved corn oil and the organic solvent. The starch is separated from the first organic slurry to obtain a solvent extracted solid starch fraction and a clarified organic solution. The clarified organic solution which contains dissolved oils is retained and may be evaporated to obtain corn oil that can be further refined.
    • 描述了不需要使用水分离谷物的无水方法,而取决于有机溶剂的使用。 所述方法包括使全谷物玉米粉与至少一种选自C1-C6醇,酮,酯或呋喃的有机溶剂接触,形成不超过15%w / w水的混合物。 将混合物分离为i)富含玉米纤维和蛋白质的固体级分,以及2)包含悬浮淀粉,溶解的玉米油和有机溶剂的液体有机浆料。 将淀粉与第一有机浆料分离,得到溶剂萃取的固体淀粉部分和澄清的有机溶液。 含有溶解油的澄清有机溶液被保留并且可以被蒸发以获得可进一步精制的玉米油。
