A finely divided composition prepared by heating and extrusion of a mixture of a cereal flour or meal or starch on the one hand and a vegetable fibrous material on the other hand is included in the mixture from which bread dough for rye bread or coarse bread types based on rye or wheat meal combined with other cereal meals or flours is made. The composition exerts the same effect as the precooked starch used in the known art, but results in improved sliceability, improved taste and a more pleasant colour, together with a better gas retention and a better machinability. A preferred composition is made from about 40% of rye meal and about 60% of wheat bran. The extrusion is performed under conditions under which a certain degree of precooking of the starch or the cereal component of the composition will take place, preferably at such a temperature that a certain degree of roasting of the product will take place, such as a temperature of 150-180 DEG C. The extrusion results in expanded, relatively crisp granules, which are then comminuted in a hammer mill or disc mill into the final composition. |
