Methods of separating a corn fiber lipid fraction from corn fiber

摘要

In one aspect, the invention provides a corn fiber lipid fraction containing phytosterols and phytosterol esters obtained via solvent extraction of a proteolyzed corn fiber, wherein the concentration of phytosterols and phytosterol esters in the lipid fraction is at least about 1.4 times greater than the concentration of phytosterols and phytosterol esters in the lipid fraction of a nonproteolyzed corn fiber.
