    摘要： The invention provides a method of separating from corn fiber a lipid fraction having phytosterol esters and phytosterols where the method has the steps of: (a) heating an aqueous mixture of unground corn fiber; (b) contacting the mixture of step (a) with at least one enzyme suitable for digesting starch for a time and at a temperature suitable to provide a mixture of an essentially destarched corn fiber and a liquid comprising soluble carbohydrates; (c) contacting the mixture of step (a) or (b) with a protease enzyme to provide a proteolyzed corn fiber and a liquid; (d) separating the liquid of step (c) from the corn fiber to provide a destarched, proteolyzed corn fiber; and (e) extracting the destarched, proteolyzed corn fiber with at least one organic solvent. A corn fiber lipid fraction/organic solvent solution having phytosterol esters and phytosterols is provided. The invention also provides a corn fiber lipid fraction containing phytosterols and phytosterol esters obtained via solvent extraction of a proteolyzed corn fiber. 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.

    摘要： This invention relates to a new composition of matter which comprises hydroxybutenyl derivatives of cyclodextrins (HBenCD) or mixed ethers of cyclodextrins where at least one of the ether substituents is hydroxybutenyl (HBenRCD where R is an ether substituent other than hydroxybutenyl). This invention also relates to novel processes for the preparation of cyclodextrin ethers. This invention further relates to inclusion complexes formed between HBenCD or HBenRCD and guest molecules. Such inclusion complexes are useful in pharmaceutical, cosmetic, and food applications. Furthermore, this invention relates to the incorporation of HBenCD or HBenRCD or their inclusion complexes in thermoplastic materials, textiles or membranes.
