Abstract: The present invention provides a process for producing ready-to-eat chow mein, which browns a mass of fried noodles so as to be able to always constantly and reliably afford elastic feeling and fragrant flavor as if it were baked on a hot iron plate. Floor, starch, salt, water and the like are mixed to make a material. The material is kneaded. The thus kneaded material is extended and rolled to a predetermined thickness to form a noodle blank. This noodle blank is cut to a predetermined width and waved to form lines of noodles. These lines of noodle are converted to ?-state and then molded to a predetermined shape. Thereafter, they are oil fried to make a mass of noodles. The oil fried mass of noodles is baked to brown its surface until the surface of the mass of noodles has a temperature increased up to 150 degrees C. to 240 degrees C.

Abstract: The present invention provides a process for producing ready-to-eat chow mein which can afford such a feeling and fragrant flavor as experienced when we eat the chow mein baked on a hot iron plate. It mixes floor, starch, table salt, water and the like to form a material and kneads the material. The thus kneaded material is extended and rolled to a predetermined thickness to form a noodle blank. This noodle blank is cut to a predetermined width and waved to form lines of noodle. These lines of noodle are converted to ?-state with a steamer. A seasoning liquid of a predetermined concentration is sprayed to these lines of noodle and then are molded into a predetermined shape. Thereafter, they are oil fried to produce a mass of seasoned and fried noodles. This seasoned and oil fried mass of noodles is baked until it has its surface heated up to 150 degrees C. to 240 degrees C. so as to brown it.
