Abstract: In some variations, the present invention provides an oil-resistant paperboard material coated with hydrophobic nanocellulose. The paperboard material is free of a fluorocarbon coating. In other variations, an oil-resistant paper is coated with hydrophobic nanocellulose and is free of a fluorocarbon coating. The hydrophobic nanocellulose may include lignin-coated cellulose nanofibrils, lignin-coated cellulose nanocrystals, or a combination thereof. A process for producing these materials is also provided, comprising: fractionating a lignocellulosic biomass feedstock in the presence of an acid, a solvent for lignin, and water, to generate cellulose-rich solids and a liquid containing hemicellulose and lignin, wherein a portion of the lignin deposits onto a surface of the cellulose-rich solids, thereby rendering the cellulose-rich solids at least partially hydrophobic; mechanically treating the cellulose-rich solids to form hydrophobic nanocellulose; and coating a paper or paperboard material with the hydrophobic nanocellulose, to generate an oil-resistant paper or paperboard material.

Abstract: The technology disclosed in this specification pertains to pectin containing cellulosic materials. The cellulosic material is modified so that it can form strong gels when dispersed in aqueous solution. Also disclosed are methods for modifying the cellulosic materials, including, at least in some embodiments, methods to monitor changes in the infrared spectrum of the cellulosic material that happen during a modification reaction to control the reaction and obtain end products capable of making gels having the desired gel strength.
