PROBLEM TO BE SOLVED: To provide noodles which require a highly shortened boiling time compared with non-grooved noodles and are still comparable to non-grooved noodles in appearance, taste, and texture after cooking.SOLUTION: The cross-section of a noodle string has a rectangular shape, wherein the noodles have a plurality of grooves formed along the longitudinal direction of the noodle string, the plurality of grooves in the cross-section of the noodle string is alternately disposed from the two long opposing sides toward the inside of the noodle string, the grooves have depths perpendicular to the long side that are greater than one-half of the length of the short side. and the total area of the noodle string portion is 20 to 50% of the rectangular shape of the cross-section.COPYRIGHT: (C)2013,JPO&INPIT【課題】麺類の茹で時間を溝なしの麺よりも大幅に短くし、かつ、調理後の外観、食味および食感において溝なしの麺と遜色がない麺類を提供する。【解決手段】麺線の横断面の形状が長方形の麺類において、麺線の縦方向に沿った複数の溝を有し、複数の溝は、麺線の横断面において、長方形の2つの長辺からそれぞれ麺線の内部へ向けて互い違いに形成され、それぞれ長辺に垂直な方向の深さが短辺の長さの1/2よりも大きく、麺線の部分の面積の合計を、その横断面の長方形の面積の20~50%とすることにより、上記課題を解決する。【選択図】図1
