    Abstract: A method of improving the utility of corn bran (i.e., hulls derived from milling) is provided. The corn bran is crosslinked with a polyvalent compound capable of forming a plurality of covalent bonds to one or more constituents of the corn bran. The crosslinked corn bran finds particular utility in papermaking. Paper furnishes and paper products derived therefrom are also provided.

    Abstract: Large diameter starch granules derived from yellow field pea, Pisum sativum (var) and faba bean, Vicia faba L. (Leguminosae) are used to replace scarce arrowroot starch granules as a protective stilt material in microencapsulated coatings, including carbonless copy paper. The "stilt" material is used to prevent premature rupture of the microcapsules and early release of the microencapsulated materials. It has been discovered that the natural granule size, and other granule properties of the yellow field pea and faba bean starches are ideally suited to replace arrowroot starch granules as a protective material. In certain coating processes in which the temperature at the coated surface exceeds the normal pasting temperature of these starch granules, the pasting temperature of the granules can be raised by a crosslinking reaction under temperature and pH conditions to preserve the granular structure of the starch particles. A polyfunctional crosslinking agent, such as epichlorohydrin, phosphorus oxychloride, acrolein, or urea-formaldehyde can be used. Under highly alkaline conditions, using phosphorus oxychloride in a stepwise reaction procedure, it is possible to increase the pasting temperature of the starch granules by more than 25.degree. F.These large diameter starch particles may also be used for other purposes, such as for anti-offset powders in lithography, either with or without crosslinking or other derivatization to further improve chemical and physical properties. These starches are also useful as absorbable dusting powders. The large granule starches derived from most varieties of peas and beans can be used in the same manner.
