Abstract: A process for producing fresh three-layered noodles by: preparing an outer-layer dough by kneading grain flour with water; preparing an inner-layer dough by adding, to grain flour, (a) at least one alkaline agent and (b) an alginic acid compound selected from the group consisting of an alginic acid, an alginic acid salt, and mixtures thereof, and kneading with water; preparing dough sheets from each of the inner-layer and the outer-layer dough through rolling of said inner- and outer-layer dough, and rolling the obtained dough sheets to make a layered dough sheet of an outer-layer/inner-layer/outer-layer structure; preparing noodle strands by cutting the layered dough sheet having such three-layer structure, and gelatinizing the noodle strands; and treating the gelatinized noodle strands with a solution of one or more acids to acidify the noodle strands.
