Disclosed is method for preparation of a starch phosphate using phytate. The method enables the preparation of a starch phosphate with improved physical properties such as high transparency, solubility, swelling power, and storage stability by the phosphorylation of a starch using naturally occurring phytate rather than using a synthetic chemical. Due to these advantages, the starch phosphate is expected to replace conventional chemically modified starches. In addition, the method enables the preparation of a starch phosphate based on a simple modification. The use of the starch phosphate greatly contributes to improvements in the quality and storage stability of various starchy foods. Therefore, the starch phosphate is expected to find application in the food industry, including starchy foods.

Disclosed are product (e.g., board), slurry, and methods relating to an uncooked starch that can be used to enhance strength in one or more gypsum layers in the board. The uncooked starch has a hot water viscosity of from about 20 BU to about 300 BU according to the HWVA method, and/or a mid-range peak viscosity of from about 120 Brabender Units to about 1000 Brabender Units.

A sulfonated nanocellulose or sulfonated cellulose may be synthesized. A polyaniline emeraldine may be doped with the sulfonated nanocellulose or sulfonated cellulose to form a sulfonated nanocellulose-doped polyaniline or a sulfonated cellulose-doped polyaniline.

Modified biopolymers, such as, charge-modified biopolymers, cross-linked biopolymers, and cross-linked, charge-modified biopolymers are provided along with methods of producing and using the same.

The present invention provides a starch with high dietary fiber content that does not deteriorate texture or flavor when added to a food. Provided is a phosphoric acid crosslinked starch obtained by subjecting a starting starch material to a phosphoric acid crosslinking treatment, wherein: when suspended in water to give a concentration of 7% by weight on the anhydrous basis, the starting starch material shows a gelatinization starting temperature of 80 C. or lower; in the phosphoric acid crosslinked starch, 70% by volume or more of particles have a particle diameter of 18-35 m; and the content of dietary fiber in the phosphoric acid crosslinked starch is 50% by weight or greater. The phosphoric acid crosslinked starch according to the present invention is useful in manufacturing compositions for dietary fiber enrichment, foods for restricting carbohydrate intake or low calorie foods.

Provided herein is a joint compound having a composition to allow tools to easily clean up, comprising water, at least one inert filler, and a binder comprising a sulfonated starch, and a method of preparing the joint compound.

A material system and method for bonding refractory powders in a three dimensional printer. A first particulate component including a refractory material is mixed with a first reactive component to form a particulate mixture. A flat layer of the particulate mixture is dispensed onto a build surface. A liquid binder, which may include a furan monomer and a surfactant, is dispensed by an ink-jet printhead onto the particulate mixture. The particulate mixture may contain a furan-soluble polymer that imposes a capillary attraction for the liquid binder, keeping it situated in the immediate vicinity of where the binder is dispensed. Additionally it provides a sufficient catalytic power to co-polymerize with the furan monomer and form a solid structure. This enables a 3D printer to build strong, accurate parts with high packing density, and to reuse the feed material many times in the printer.

The present invention relates to a novel process for manufacturing a sugar acid for the use in the agricultural market as an adjuvant wherein the process includes the following steps of providing a reactor and introducing a source of nitric acid, water and a source of starch into the reactor to form a mixture and further includes introducing an external heat source to the mixture to ascertain a mixture temperature of at least 70? C. and discontinuing the external heat source once the mixture reaches about 70? C.; and further enabling an internal heat source in the form of an exothermic reaction to occur between the reagents for at least two (2) hours. The invention also relates to the use of the product as obtained from the process.
