Method and system for production of zein and/or xanthophylls using chromatography

Fangyi Zhu (Inventor), Philip L Shane (Inventor), Munir Cheryan (Inventor), Aniket Kale (Inventor)

Research output: Patent

Abstract

Methods and systems for obtaining zein and/or xanthophylls in highly pure form. Zein is first extracted from corn using aqueous ethanol. Suspended corn solids are separated, and the resulting extract is purified in a single size-exclusion chromatography step to separate impurities and produce substantially purified zein. The chromatography step may simultaneously produce substantially purified xanthophylls.
