GROOVED NOODLE
Grooved noodles have one or a plurality of grooves formed along a noodle length direction, the traverse cross-section of the noodle length has a substantially circular main outer shape, and the grooves extend in a spiral shape in the noodle length direction.
1 . A grooved noodle having a single groove or a plurality of grooves formed along a longitudinal direction of the noodle and having a substantially circular configuration in cross section,
wherein the single groove or the plurality of grooves extend helically in the longitudinal direction of the noodle.
2 . The grooved noodle according to claim 1 , wherein the plurality of grooves comprise two to four grooves arranged at substantially equal intervals.
3 . The grooved noodle according to claim 2 , wherein the plurality of grooves are formed helically in a same direction.
4 . The grooved noodle according to claim 1 , wherein the single groove or each of the plurality of grooves has a helical shape formed at a rotational pitch of 20° to 200° per a noodle length in the longitudinal direction 125 times a noodle diameter.
5 . The grooved noodle according to claim 1 , wherein a cross sectional area of the single groove or the plurality of grooves accounts for 10 to 50% of a hypothetical cross sectional area of the noodle when it is assumed that no groove is provided.
