Abstract
Extruded elongate pasta is disclosed, each pasta strand having at least one groove formed longitudinally in the pasta strand in such a manner that the total cross sectional area of the groove is 2 to 25% of the cross sectional area of the pasta strand, and the groove in the pasta strand is substantially closed after the elongate pasta is boiled or dipped in hot water. A die structure for extruding the elongate pasta is also disclosed, the die structure being so arranged that a projection is projected toward the axis of a die hole from the inner surface of the die hole and that the coefficient of friction of the inner surface of the die hole is 0.4 or less. It is preferable that a tapered portion is formed on the upstream end of the projection. Further, an extruder for forming the elongate pastas which has a number of such die holes is also disclosed, in which projections of the die holes are projected perpendicularly to the aligning direction of the die holes.
