Abstract: The present invention relates to a method for treating, and in particular for abrading surfaces, utilizing glass-like polysaccharide grits. The invention also extends to novel glass-like polysaccharide products, especially starches, and to processes for the production thereof. Additionally, there is disclosed cross-linked polysaccharide materials and glass-like starches having a substantially occluded water component. Combinations of these various polysaccharide grits and other abrasive grit materials are also disclosed.

Abstract: A sheet-like paper article is provided with a dry adhesive coating which can be rendered tacky by wetting with water at room temperature by preparing a starch-based adhesive preparation comprising an aqueous slurry of cold water swellable starch in water, the slurry also containing an alcohol selected from the group consisting of methanol, ethanol, propanol, butanol, hexanol, decanol, their isomers and mixtures thereof, and the alcohol having a concentration sufficient to substantially prevent the water from causing the starch to swell. The alcohol may be partly or completely replaced by a glycol, for example ethylene glycol or propylene glycol. The aqueous slurry is coated on a surface of the paper article, and the coated paper article is heated to remove the alcohol and/or glycol and water from the slurry coating and provide a dry starch-based adhesive coating which can be rendered tacky by wetting with water at room temperature.

Abstract: A process for manufacturing vital wheat gluten with substantially no objectionable flavor or aroma includes extracting gluten from wheat or wheat flour in an aqueous process to provide vital wet gum wheat gluten which is then mixed with an aqueous preparation containing an amount of antioxidant effective to prevent production of an objectionable flavor or aroma in a subsequent drying step. The aqueous antioxidant/gluten mixture is dried to produce dried vital wheat gluten with substantially no objectionable flavor or aroma.
