Abstract

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.

Claims

exact text as granted — not AI-modified

What is claimed is:  
     
         1 . A corn fiber lipid fraction containing phytosterols and phytosterols esters obtained via solvent extraction of a proteolyzed corn fiber, wherein the concentration of phytosterols in the lipid fraction is at least about 1.4 times greater than the concentration of phytosterols in the lipid fraction of a nonproteolyzed corn fiber.  
     
     
         2 . The corn fiber lipid fraction of  claim 1 , wherein the corn fiber is destarched prior to solvent extraction.  
     
     
         3 . The corn fiber lipid fraction of  claim 1 , wherein the corn fiber is unground.  
     
     
         4 . A corn fiber lipid fraction containing phytosterols and phytosterol esters obtained via solvent extraction of a proteolyzed corn fiber, wherein the concentration of phytosterol esters in the lipid fraction is at least about 1.4 times less than the concentration of phytosterol esters in the lipid fraction of a nonproteolyzed corn fiber.  
     
     
         5 . The corn fiber lipid fraction of  claim 4 , wherein the corn fiber is destarched prior to solvent extraction.  
     
     
         6 . The corn fiber lipid fraction of  claim 4 , wherein the corn fiber is unground.
