1. A process of producing a solid paste composition for heat cooking, the process comprising the steps of:
(i) preparing a paste dough composition having an insoluble dietary fiber content of 1.5 mass % or more in terms of wet basis, a starch content of 5.0 mass % or more in terms of wet basis, a protein content of 3.0 mass % or more in terms of wet basis, and a dry mass basis moisture content of 25 mass % or more;
(ii) kneading the paste dough composition prepared in step (i) at a temperature of from 100° C. to 200° C. with a specific mechanical energy (SME) of 350 KJ/kg or more to form a kneaded paste dough composition; and
(iii) cooling the kneaded paste dough composition to a temperature of less than 90° C.,
thereby forming the solid paste composition, wherein
the kneading in step (ii) and the cooling in step (iii) are both carried out with an extruder, and
a temperature difference between a maximum heating temperature during the kneading in step (ii) and a lowering temperature in step (iii) is 30° C. or more.
