Coated articles are also provided.

Basecoat coating compositions comprising low molecular weight cellulose mixed esters

Cellulose mixed esters are disclosed having low molecular weights and low degrees of polymerization. These new cellulose mixed esters include cellulose acetate propionate and cellulose acetate butyrate. The esters exhibit solubility in a wide range of organic solvents with minimal viscosity increase, are compatible with a wide variety of resins, and are useful in coatings and inks compositions as binder resins and rheology modifiers.

Low molecular weight cellulose mixed esters and their use as low viscosity binders and modifiers in coating compositions

Carboxyalkylcellulose esters are disclosed having relatively low degrees of polymerization. These new carboxyalkylcellulose esters include carboxymethylcellulose acetate, carboxymethylcellulose acetate propionate, and carboxymethylcellulose acetate butyrate. The inventive esters exhibit solubility in a range of organic solvents, and are useful in coatings and ink compositions as binder resins and rheology modifiers.

Low molecular weight carboxyalkylcellulose esters and their use as low viscosity binders and modifiers in coating compositions

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.

Methods of separating a corn fiber lipid fraction from corn fiber

The invention provides a method of obtaining a cellulose material from corn fiber wherein the method comprises the steps of: (a) heating a mixture of corn fiber and a liquid; (b) contacting the mixture of step (a) with a protease enzyme, thereby providing a proteolyzed corn fiber and a liquid; (c) separating the liquid from the proteolyzed corn fiber; (d) contacting the proteolyzed corn fiber at least once with an alkaline extractant, thereby providing an insoluble cellulose material and a first liquid comprising arabinoxylan; (e) separating the insoluble cellulose material from the first liquid comprising arabinoxylan at a temperature of at or above about 60&deg; C.; and (f) rinsing the insoluble cellulose material to remove essentially all alkali, thereby providing a cellulose material having a cellulose content of at least about 50% and consisting essentially of cellulose I.
