Abstract: A method for producing a starch-containing solid composition for heat-cooking utilizes an extruder that contains a screw that is turned by a motor; a barrel that surrounds the outer periphery of the screw; a feeder that is attached to the base side of the barrel and that is for loading a food material; and a die part that is attached to the tip side of the barrel and that is for discharging the food material after kneading while shaping the food material. The screw has, in order from the base side to the tip side, at least a flight section and a kneading section. The length of the flight section is not less than 50% of the entire length of the screw. The length of the kneading section is less than 50% of the entire length of the screw.

Abstract: A manufacturing method for a starch-containing composition that is not prone to collapsingshape in a liquid during heat cooking, is highly lusterless, and has excellent appearance which utilizes an extruder including a feeder for loading a food material and a die for discharging the food material after kneading and shaping. The screw has a first flight, a kneading, and a second flight section, and the barrel has a bend section at the first-half of the second flight section of the screw. A composition containing at least 3.0 mass % insoluble dietary fiber, at least 10.0 mass % starch, at least 3.0 mass % protein, and a dry-basis water content of at least 25 mass % is prepared.; The composition is then heated under pressure, kneaded, and depressurized until the degree of gelatinization is lowered by at least 6 mass %.

Abstract: A solid paste composition for cooking, which has elasticity, suppresses a rubber-like texture, and has a good chewy texture. The solid paste composition satisfies containing 2.0 mass % or more of an insoluble dietary fiber in terms of dry mass, 15 mass % or more of a starch in terms of dry mass, and 5.5 mass % or more of a protein in terms of dry mass. The solid paste composition further satisfies at least either of the ratio of the number of CBB-stained sites having an area of at least 200 ?m2 and a roundness coefficient of at least 0.3, to the number of CBB-stained sites being 3% or more, and the ratio of the total area of CBB-stained sites having an area of at least 200 ?m2 and a roundness coefficient of at least 0.3, to the image area of a cross-section of the composition being 0.3% or more.
