A sustained release composition containing a chemical substance in a matrix. The matrix substantially comprises a hemicellulose extracted from wheat bran under alkaline conditions or a wheat bran extract containing the hemicellulose. The chemical substance is released at a controlled rate from the composition over a long period of time.

A new water-insoluble modified gluten product and a new water-soluble proteinaceous substance have now been found to be produced by kneading a mixture of wheat flour, one or more oxidizing agents such as L-ascorbic acid, potassium boromate, ammonium persulfate and potassium iodate, and water and then separating or fractionating the resulting dough-like or batter-like, hydrated flour mixture as kneaded, for instance, by repeated water-washing or centrifugation, so as to give individually a fraction comprising the water-insoluble modified gluten product, a fraction comprising an aqueous solution containing the water-soluble proteinaceous substance dissolved therein, and a fraction comprising the starchy substances and if necessary, subsequently dehydrating said aqueous solution. The water-insoluble modified gluten product and the water-soluble proteinaceous substance so obtained as well as a mixture of these are each useful as new bread improver for addition to farinaceous flours or bread-making doughs for the purpose of improving the properties of bread or other bakery products, such as the volume, crumb texture and crumb smoothness of bread.
