1. A method of producing sterilized packed pasta while preventing specks from appearing thereon, said method comprising the steps of:
filling a container with pasta and water;
boiling said pasta in said container inside a retort at Fo value of 0.1-1.5 while repeatedly increasing pressure inside said retort and releasing pressure inside said retort under conditions wherein said water is evaporated and a foamed portion of said water covers floating portion of said pasta, wherein the pressure inside said retort is increased to a higher level of 0.13±0.02 MPa and is released down to a lower level of 0.11±0.02 MPa, and wherein said higher level and said lower level are different by 0.01-0.05 MPa; and
thereafter sealing said container inside a clean booth;
wherein said steps of increasing and releasing pressure inside said retort are repeated at a rate of 1-4 cycles per minute; and
wherein said steps of increasing and releasing pressure inside said retort are carried out such that temperature inside said retort is 105±3° C. after said pressure is increased and 102±2° C. after said pressure is released and that temperatures in said retort after said pressure is repeatedly increased and released are different by 2-8° C.
