GROOVED NOODLES

Grooved noodles formed with four grooves along a longitudinal direction of the noodles and having a substantially circular configuration in cross section.The four grooves are arranged at intervals of 90° along a circumferential direction of the noodles and extend in a same rotational direction with respect to a center point in a cross section of the noodles.Each of the grooves includes a pair of sides opposing to each other and extending from an opening part of the groove toward an innermost part of the groove, a first opening end part located on one side of the pair of sides closer to the center point, and a second opening end part located on another side of the pair of sides farther from the center point.An acute angle formed between a straight line passing through the first opening end part and the innermost part and another straight line passing through the first opening end part and the center point in each of the grooves is 12° to 33°.A center region defined in a quadrilateral formed by four straight lines each passing through the innermost part and a middle point between the first opening end part and the second opening end part of a relevant groove has an area of 4% to 35% of a hypothetical area of the configuration when it is assumed that the four grooves are not provided.The noodles accounts for at least 85% of the center region.
