Abstract: A process for preparing instant macaronis which comprises adding an egg white, a yam and an aqueous soution of a carbonate as a first kneading water to a wheat flour, half-kneading and aging the obtained mixture, further adding an aqueous solution of an organic acid as a second kneading water and kneading the mixture, molding it into a desired shape, boiling the molded alimentary paste in an aqueous solution of common salt, surface-treating the boiled alimentary paste with a solution of glucose in an alcohol-water mixed solvent, and freeze-drying the treated alimentary paste. The instant macaronis can be rehydrated to macaronis having excellent taste, texture and color tone in a short period of time by merely pouring a boiling water on the macaronis.
